787 Certification Flight can start as early as January 3rd
ZA004 made a successful return to test flight yesterday by flying a 1 hour and 35 minutes test flight around the Seattle/ Puget Sound region.
Here's the current flight test statistics that I've been keeping:
On Dec. 20th there was a line move and the 31st 787 (ZA117/LN31 for ANA) entered final assembly in Boeing's 40-26 final assembly building. LN 27 (ZA178 for Japan Airlines) went to the paint hangar. I have a fully updated spreadsheet below of the current status of the 787s around Everett:

Boeing announces the resumption of flight tests
Boeing Resumes 787 Flight Testing
- Interim solution verified through extensive testing
- Schedule assessment expected to conclude in January
EVERETT, Wash., Dec. 23, 2010 /PRNewswire/ -- Boeing (NYSE: BA) will resume flight test activities on the 787 Dreamliner later today. The company has installed an interim version of updated power distribution system software and conducted a rigorous set of reviews to confirm the flight readiness of ZA004, the first of the six flight test airplanes that will return to flight.
"Initially, we will resume a series of Boeing tests that remain to be completed in the flight test program. That testing will be followed later by a resumption of certification testing," said Scott Fancher, vice president and general manager of the 787 program. Today's testing will include an intentional deployment of the Ram Air Turbine (RAT), which is a small turbine that is deployed when back-up power is required.
Boeing and Hamilton Sundstrand completed testing of the interim software updates earlier this week. Verification of the system included laboratory testing of standalone components, integration testing with other systems, flight simulator testing and ground-based testing on a flight test airplane.
In the last several weeks, the company continued ground testing as part of the certification program. Additional ground testing will be done by the company on the production version of the airplane to further verify performance of the changes being made.
"As we return to flight test and determine the pace of that activity, we remain focused on developing a new program schedule," Fancher added. "We expect to complete our assessment of the program schedule in January."
Flight testing of the 787 was suspended last month following an in-flight electrical incident on a test flight in Laredo, Texas.
A couple of key points:
1) Testing is being done on an interim software fix. This is not the final version that will be required on all production planes
2) Boeing tests - Boeing is conducting these test not the FAA
3) The first test involves the deployment and testing of the RAT - Did the RAT not work as expected on ZA002?
4) One 787 will return to flight test, the others?
Ok my take....Boeing is going to be testing an interim software fix; hardware fix, it seems, is done. The FAA is more concerned with the way the power distribution systems handled during the in flight emergency on ZA002. Now this software fix is going to run through different scenarios and test conditions to see how it reacts. Boeing is going to have to demonstrate to the FAA the power distribution software will react in way intended in the case of an in flight fire. Because this is an interim fix I expect that there will be changes made that will have to be tested in the systems integration and engineering lab before being flown on ZA004 which I assume will be the test bed for this software fix.
Until the FAA is 100% satisfied that this fix does not allow the recurrence of the problems that the crew experienced on the flight deck, Boeing will have to continue to make changes to the software and test it in the ground labs and in flight test before the FAA will allow certification testing to restart. Boeing tells me that they are having continued discussions with the FAA over the resumptions of certification test flights which I presume will include a discussion of the results of the Boeing flight tests and the software fixes that are being tested.
Boeing has told me a couple of tid bits.
1) All the flights that occurred on November 7th including the ferry flights will be logged as official 787 flights. This includes ZA002's flight. It should appear on the 787 flight test scorecard. It is already on my flight test tracker and I will update it for all flight that are carried out for today onwards.
2) The other 787s will be rejoining the flight test program in the days and weeks ahead. ZA004 will not be the only 787 flying in these Boeing tests.
3) An industry source has told me that Boeing plans to have the new delivery schedule ready around the week of January 17th though it is not a certain time frame. A lot will depend on how these test flights go as well as complete review of the work that the program has to complete on all the built 787s that are scattered all over Everett.
Lastly, Guy Norris has a post up on the Aviation Week site. In it he reveals that Boeing is getting the systems labs operational again to fully support the flight testing of the oftware fix. Guy also says that Boeing expects to see certification flight testing to resume sometime in January.

Guy Norris: 787 Return to Flight
Resumption of 787 test flights...my take
Boeing, in my opinion got FAA approval, to resume test flights with Boeing personnel in order to collect data on the fixes that needed to be made in light of the November 9th fire on ZA002. Boeing has to prove out the hardware and software changes in order to give the FAA satisfaction that there won't be a recurrence of the problems that lead to the fire and the resulting loss of power which necessitated the deployment of the RAT (Ram Air Turbine) to provide power to critical systems while the aircraft was landing in Laredo. Once Boeing has collected the data analyzed it and presented it, then the resumption of Certification test flights will hinge on if the FAA has comfort in Boeing's analysis.
Boeing expected to announce resumption of test flights.
UPDATE: Bloomberg is also reporting that Boeing will resume 787 test flights but they will only be company test flights only and not counted towards FAA certification purposes.
Various sources have confirmed that Boeing is finalizing plans to announce a resumption of test flights with this announcement possibly coming after the market close today, Dec. 23rd. Boeing is not expected to announce a new delivery schedule however and various industry sources have told me that this announcement could come sometime around the release of Boeing's 2010 earning release in late January. The return to test flights can resume as early as today.
While the resumption of test flights is a major step forward for the 787 it is still disconcerting that Boeing doesn't have a delivery schedule ready. This points to the other issues that have plagued the program, namely the amount of unfinished work that has to be completed on the assembled jets and the ones that have yet to be assembled. According to Dominic Gates this amounts to about 140,000 individual jobs spread across the aircraft that have been produced (24 airplanes). Some would take a few hours while others would take a few weeks. Boeing, I believe, is trying to get its arms around the scope of work that has to be completed, what it will take, how long it will take and the investment needed to finish these airplanes.
Looks like I only got half a present I wanted for Xmas...

All I want for Xmas....is a 787 schedule
There is a report that Boeing may have solved some of the electrical issues to the satisfaction of the FAA which may allow Boeing to resume test flights as early as this weekend, I believe this is doubtful as Boeing is basically shutdown from Dec. 24th through January 2nd for the Holidays. A source has told me that they were looking to resume test flights around Dec. 23-24th but now this is looking doubtful. Boeing has been in very frequent (daily) meeting with the FAA over the resumption of test flights and certification though. However it may not be too much of a stretch that Boeing has resolved issues to the FAA satisfaction. Boeing Japan President, Michael Denton, has said that Boeing is expected to announce a return to test flights soon though he didn't have an update for the delivery schedule.
The fact that Boeing maybe returning to test flights soon is good news the fact that they may still be weeks away from announcing when deliveries would start is troubling. It may indicate that the real issues are the unfinished work, supplier problems and on going engineering changes which won't be improved upon to support a near term delivery schedule.
The FAA is coming down hard on Boeing to such an extent that ETOPS certification out of the box may be in serious jeopardy according to Dominic Gates of the Seattle Times.
In an article that was published 5 days ago, Dominic described the amount of work that has to be done on the Dreamliners that are already assembled. His sources have told him that there about 140,000 incomplete items on all these airplanes that have yet to be done, either in Everett or in San Antonio where crews will put the 787s through the change incorporation program and prepare these airplanes for delivery. One 787 (one for Air India) has been on the Boeing flightline without the horizontal stabilizer indicating that Boeing is still dealing with the poor workmanship from Alenia.
Dominic Gates: Dreamliner's woes pile up
Boeing to boost 777 output 66 percent by 2013 amid 787 delays
Lastly, Flightblogger has published an extensive article on the 787 business case. In it he describes how the deep discounts that Boeing gave on the 787 has put Boeing under fiscal pressure to make a profit on this program. The discounts were on the order of around $65mm that was given to one large airline who placed a very large order. Boeing had calculated that the program would cost about $5bn and now estimates are for around $12bn - $18bn additional after factoring in cost overruns, compensation to customers, and additional resources needed to finish all the outstanding work.

One Year In....The 787 year in review.
787 - December 15, 2009 to December 14, 2010
December 15, 2009 was a day that Boeing hoped that see the start of putting the troubles of the 787 program in the rear view mirror. It was a day that cloudy and rainy (typical Pacific Northwest weather). The first 787, ZA001, made an on time takeoff and flew for a little over 3 hours. ZA002 flew one week later in a flight that was shortened by issues with the main landing gear door and the nose gear. Nevertheless these initial flights started Boeing on the path of initial airworthiness flight trials. The 787 achieved IAT in mid January 2010 which allowed Boeing to conduct test with the other test flight airplanes as well as with engineers on board. This allowed for the expansion of the787 flight test envelope which would include stability and control testings, flutter testing and functionality and reliability testing of the airplane.
Boeing added airplanes to the test flight fleet with ZA004 flying in late February, 2010 and ZA003 flying in mid March 2010. The near term goal of the program was to achieve Type Inspection Authorization for the 787. This is the point that would formally kick off the certification program for the 787. This point of the program was expected to be achieved by mid to late February, 2010 but was not granted until April 20, 2010. This was a major indicator that the program may suffer delays to the delivery schedule yet again. During this period Boeing had successfully test the 787 wing to the ultimate load limit test on ZY997, the static test airframe. This was a major certification test point that Boeing needed to accomplish given the issues that Boeing had found almost a year earlier with the side of body join and the weakness that was discovered.
Boeing continued testing throughout the spring and summer of 2010. They seemingly hit a very good flight test pace during late May/early June only to see the number of flight and flight hours flown to drop off a month later and then recover later in the summer. Progress was made in September through the early part of November with significant flight hours being posted especially with the GEnx powered 787s that had finally joined the flight test program. However there were set back to flight testing (and production) due to the time needed to inspect the horizontal stabilizers on all 787s due to Alenia's workmanship issues. Boeing needed to spend precious time and resources to inspect and conduct any repairs on the aircraft that were built and/or flying. Still despite the Alenia debacle, Boeing was still on track to deliver the 787 by end of 2010 until an early August Trent 1000 engine test in Derby, UK took a bad turn and the engine had an uncontained failure of it intermediate pressure turbine.
This was a major setback for Rolls and Boeing as it threw the entire schedule into doubt. Indeed, the engine that failed was due to be installed on ZA102 (LN 9) which was to be used for flight tests of production standard aircraft. Boeing had to delay delivery to mid February because of the unavailability of an engine for ZA102 within the needed time frame to start flight tests on this aircraft.
Still Boeing said they were confident in Rolls Royce's hardware and software fixes to prevent a recurrence of the failure and Boeing continued with flight and ground testing of the 787 through early fall until Nov. 9th.
ZA002 was flying a long duration test flight with FAA personnel aboard testing the nitrogen generating system (part of the fuel inerting system) and was on final approach to an airport in Laredo Texas when a fire erupted in the lower electronics bay near the left wing. The fire was out after about 30 seconds but the power panel where the fire originated was destroyed and the aircraft had experienced power distribution problems while in the process of landing. An emergency was declared (apparently after landing) and the crew and test personnel evacuated the aircraft using the emergency slides.
The problems that lead to the fire in the P100 power distribution panel are now well known but now at this point, one year after the first 787 flew the 787 schedule is in shambles. The aviation world is waiting for Boeing's revised schedule. The 787 has had more than its fair share of problems and delays since it was launched in 2004 and there's nothing to say that there won't be any more issues when Boeing and the FAA resumes flight testing.
Boeing is still encountering supplier and production issues and probably will continue to see sporadic halts to part deliveries into Everett. Clearly there is still plenty of issues that need to be cleaned up so that Boeing can start deliveries of the 787 and ramp up production. However, the aviation world is now waking up to the fact in light of problems in various aircraft programs (A380, 787, A400M, F-35, and the A350) that the old model that aircraft manufacturers used to develop, design, test and produce high technology aircraft is out the door. Robert Wall of Aviation Week summed it nicely in a blog post a week ago: "Skeptics quip that Airbus is effectively fighting the last war, and that the only thing it is assuring is that it will invent a whole new series of missteps. If that turns out to be true, then perhaps it is time to put to bed the idea of accelerating development cycles on major products and just learn to live with the fact that the gestation period for a major civil aircraft program is eight years or longer."

Guy Norris: Electrical contactors in P100 is possible source where fire started
Another bit of news is that the insulation between the fuselage and the P100 power panel was charred and had been effective in protecting the composite skin of the fuselage. This has been a point of debate in some circles and now apparently the insulation did protect the fuselage as it was meant to do. This should give Boeing and the FAA some comfort.

Guy Norris: Mid-2011 delivery for delayed 787?
French Newspaper: 787 to be delivered late June to early July
If true this would be a four and a half month delay. The newspaper reports that fixes should be done by the end of December with test flights resuming in January. This all, of course, is dependent on FAA approval of the required fixes. Click here for the Les Echos article. The translation is below (by Google Translate):
If no date is yet officially adopted, the first deliveries of Boeing 787 could ultimately involve next summer - perhaps late June or early July. Or with a little over three months late on the last date. This was suggested yesterday some Boeing executives to their counterparts in Air France, alongside the delivery of a B777 to the French company.
For now, the six copies of the 787 tests are still grounded, a month after a fire in a cabinet during a test flight, which resulted in the interruption certification program. But Boeing engineers believe they have identified the source of the problem and possible solutions to them.
The fire was caused by the presence of particles in the closet - and not a forgotten tool as has been mentioned. The short circuit would result in a blackout then the electricity network, despite the security software. Boeing and its partners to the electrical system, Hamilton Sunstrand and Zodiac, have therefore set about rewriting the computer program key.
The aim would be to complete corrections by the end of the year, to resume test flights in January, and lead to certification in June. However, the manufacturer must obtain clearance from the FAA, U.S. Civil Aviation, before resuming its flight tests. If all goes as planned, the consequences of this seventh postponement since the launch of the program would thus without serious consequences on the delivery schedule.
Boeing has 26 Dreamliners on hold on its site in Everett, the colors of All Nippon, Air India and Japan Airlines, which it only needs the engine still installed at the last moment, and the buffer FAA to be delivered. In addition, a second assembly line 787 should start in the summer of 2011 in Charleston, to help make up for lost time.
There is also an article in the Economic Times referencing the same Les Echos article:
Economic Times: Boeing Dreamliner delivery delay to July: Report
Monday, December 6, 2010
Boeing initiates 3 week 787 production halt; production to resume on Dec. 23rd.
This news comes on top of Spirit Aerosystems announcing that they were temporarily halting production of the 787 forward fuselage sections and reassigning those workers to help with 737 overtime production. Spirit currently has 50 forward fuselage sections either delivered or in the production process in Wichita. It is probably unrelated to the current production halt as Boeing is telling it's suppliers to continue their production and delivery schedules. Flightblogger reported that the main fuselage section for ZA117 has not arrived into Everett leading me to believe that Boeing Charleston might be the source of the current production delay.
This is the 4th production halt this year as Boeing is still attempting to ramp up production of the 787. This only adds to the problems the program is facing in the midst of the power panel fire on ZA002 and the subsequent need to initiate re-design of hardware and software in the 787. It is still unknown when the 787 will return to test flight though I think it'll happen between the first and second week of January.

ZA002 to fly back to Boeing Field, Boeing still expects to issues new schedules in the next several weeks
Flightaware ZA002 track
Here's Boeing's press release:
ZA002 Returning to Seattle
In related news Boeing Commercial Airplane chief, James Albaugh said that Boeing still has more work to do in order to finalize plans for the necessary modifications and fix to the power distribution system and then develop a schedule based on that and probably other considerations in the program. Albaugh is saying that there will be a schedule slip which is expected but has not yet said how long that slip would be. His comments were to Reuters. You can read the article by clicking HERE.Boeing has readied ZA002, the 787 flight test airplane that experienced an electrical fire on Nov. 9, to be flown from Laredo, Texas, to Seattle. Maintenance technicians replaced the damaged P100 power distribution panel, repaired damage to interior composite structure and installed new insulation material.
The team in Laredo, Texas, has completed a series of ground test operations and
inspections to validate the repairs. The flight, which is expected to occur soon, will not include test operations.
Still all this is not sitting well with customers for the 787. ANA is demanding a new schedule as well as details about the problem that caused the fire and subsequent power problems. Qatar Airways has called the 787 a "failed" program though it seems that they're still holding on to their order for 30 787s. China Eastern Airlines is saying that they will cancel their order for 15 787s though Shanghai Airlines, which is owned by China Eastern, has not said if they too will cancel.
It is too early to tell if customers will stick with Boeing and the 787 until the revised schedule is out.
Still Boeing is still continuing with production with the 31st 787 to be loaded into position 1 today or tomorrow. This airplane, ZA117, is destined for ANA. ZA178 which is for Japan Airlines will be rolled out to the paint hangar.
Ground test continue to be performed on the 787 test flight fleet in lieu of flight tests as well. Boeing is also making progress in terms of getting the other 787s ready for flight tests and delivery. As had been reported earlier, a 787 destined for Japan Airlines received it's GEnx-1B engines this past weekend and one of the production 787 that will undertake flight/ground testing was rolled out to the flightline. I had reported that this airplane was ZA102 but it might be ZA101 which is to take part in ground tests though I'm working to try and confirm which aircraft is actually out on the flightline.
Flightblogger reported today that production airplanes will be flown to San Antonio, Texas where they will go through the change incorporation program prior to being delivered. Flightblogger is reporting that the Japan Airlines 787 (ZA177) will be the 3rd or 4th 787 to be delivered. It seems that now production airplanes are starting to get their powerplants in preparation for the flights to San Antonio though when these airplanes will be flown will be determined by the new schedule that Boeing should put out in the next several weeks.
Flightblogger: Repairs complete in Laredo, ZA002 to return home to Seattle
Lastly, I am still standing by my earlier prediction of a three month delay for 787 deliveries.

Boeing: Changes to Power Panel Design; revised schedule still weeks away
As a consequence Boeing will undertake a minor redesign of the power panel to reduce the chance of FOD creating and electrical arc or short circuit. Boeing will also implement software changes to make sure that power distribution is improved. This appears to be an acknowledgement that the electrical power redundancies failed as well.
Boeing did not present a revised schedule as they have yet to work that out but they are saying it should be ready in a few weeks. They are developing a plan to present to the FAA for the resumption of flight tests as well asto ferry ZA002 back from Laredo.
Also Flightblogger reports that the foreign object was small and not something the size of a tool as had been earlier reported. KING 5, a Seattle TV station says that it was a washer that caused the short circuit.
Again there is no word on how long it will take the implement the redesign or the software changes. Additionally, the FAA will have to approve all these changes so the schedule will remain in flux.
Boeing will be closed tomorrow and Friday for the Thanksgiving holidays.
Here is Boeing's press release:
Boeing Initiates Changes to 787 Power Panel, Updates to Software
EVERETT, Wash., Nov. 24, 2010 /PRNewswire/ -- Boeing (NYSE: BA) is developing minor design changes to power distribution panels on the 787 and updates to the systems software that manages and protects power distribution on the airplane. These changes come as the result of what has been learned from the investigation of an onboard electrical fire on a test airplane, ZA002, earlier this month in Laredo, Texas.
"We have successfully simulated key aspects of the onboard event in our laboratory and are moving forward with developing design fixes," said Scott Fancher, vice president and general manager of the 787 program. "Boeing is developing a plan to enable a return to 787 flight test activities and will present it to the U.S. Federal Aviation Administration (FAA) as soon as it is complete."
Engineers have determined that the fault began as either a short circuit or an electrical arc in the P100 power distribution panel, most likely caused by the presence of foreign debris. The design changes will improve the protection within the panel. Software changes also will be implemented to further improve fault protection.
The P100 panel is one of five major power distribution panels on the 787. It receives power from the left engine and distributes it to an array of systems.
The 787 team is now assessing the time required to complete the design changes and software updates that are being developed. A revised 787 program schedule is expected to be finalized in the next few weeks.
"Our team is focused on developing these changes and moving forward with the flight test program," said Fancher. "The team in Laredo is also well along in preparing to return ZA002 to Seattle.

Scott Hamilton: 78 fire caused by FOD, design changes coming, no word on delay
Randy Tinseth: Likely cause of ZA002 incident determined
Aubrey Cohen: Boeing: 787 will need minor changes; schedule impact unknown
At the end of the day everyone wants to know what is the schedule impact of the fire and the resulting redesign of software and hardware. A source told me that he believes that it would set back the 787 no more than three months. Given the information that has come out thus far and my discussions with sources, I do feel that mid to late May delivery time frame is probably about right given the redesign efforts as well as the rework that has to be done on the production aircraft.

KING 5 also says that Boeing is expected to make a statement today. The stock market is closed so it should be out soon. Stay tuned....

Flightblogger: 787 fire investigation coming to an end
Indications are pointing towards FOD as the culprit but there is still open questions as to what the FOD was and where was it located. Additionally, a more important flag was raised about the 787s power redundancies in case of a loss of a unit like P100.
Fligthblogger also revealed that Boeing was able to recreate the effects in the systems integration lab.
Boeing needs to understand why the 787 had assumed that all power was loss and the RAT was deployed (it only deploys in the event of a total power loss). This might necessitate a software and/or hardware fix though it is not known at this time.
On a related note, Susanna Ray of Bloomberg News put out an article where Wall Street analysts say that a 7th delay is a foregone conclusion. Dominic Gates also has an article detailing the investigation and the possibility that FOD played a role in the fire.
The fire may have revealed a potential problem with how power is distributed in the event one of the power distribution panels failed like the P100 did. It is better to find these issues now instead of an revenue flight with 200 passengers on board.

French Newspaper: Forgtten tool in P100 sparked fire
A foreign body may have triggered the fire that broke out Nov. 9 on a test flight of a Boeing 787, forcing since the American manufacturer to suspend his campaign test flight within 3 months delivery date official said Monday The Tribune.
"A tool, forgotten in a cabinet (which is software components, ie), has caused a short circuit," according to comments from industry sources reported by the daily La Tribune.
However, this would not have such consequences, notes the newspaper, noting that the entire power distribution system is at stake.
The Tribune added that several manufacturers are involved, including French Zodiac, one of the subcontractors of the American Hamilton, supervisor of the electricity distribution and Boeing aircraft, Specifications and controls.
And translation of the La Tribune article:
Incredible as it may seem, it is a forgotten tool in a cabinet that is at the origin of the fire on 9 November that forced Boeing to halt flight testing of the B787. Although detected, the anomaly still poses problems for engineers who need to understand how to prevent it from reproducing. Among the subcontractors in the crosshairs: French Zodiac.ZA004 did make the ferry flight to Everett yesterday though ZA003 has not returned to Boeing Field as of yet but Guy Norris is reporting that ZA002 being prepped for a return flight back to Boeing Field though no date has been set. Additionally, ZA001 is now entering a lay up period for maintenance with ZA004.
FOD for "foreign object damage" or damage caused by foreign body. That, according to several industry sources, the triggering element of the fire that broke out Nov. 9 on a test flight of a Boeing 787, forcing since the manufacturer to suspend its test campaign flight three months after the first delivery to All Nippon Airways. "A tool, forgotten in a cabinet (which is software, components ..., ed) caused a short circuit," says Will we at The Tribune.
However, this should not have such consequences. Because the whole system of power distribution, a crucial point in the plane, which is involved. "For security, everything is redundant in a plane. But the blackout that occurred in the first cabinet spread to the second, and the aircraft had to use emergency power management to ask, "say the sources. This is a small wind turbine (called the rate) that is located on the fuselage and a small generator supplying emergency power for the aircraft to land.
Several manufacturers are involved in this can of worms. Including French Zodiac one of the subcontractors of the American Hamilton (subsidiary of United Technologies), supervisor of distribution of electricity in the air, and of course Boeing, Specifications and controls. The French equipment provides such components in the cabinet. Hamilton provides other. "However, you can not blame anyone for now, says one industry, as more than a problem of quality of play is a problem in the logic of management of the electrical system since the breakdown spread. "
Nevertheless, the results of races may be final. The Boeing 787 was headed straight for seventh behind. It is even a certainty for the highly respected Steven Udvar-Hazy, head of aircraft lessor Air Lease Corporation. "If changes are needed on some software, it will take time and aircraft deliveries will be postponed," said a French industrialist. Morgan Stanley, such a scenario could shift the first deliveries of the aircraft at 2012. They were laid in 2008, when launching the program in 2004.

Guy Norris: Another brief 787 flight
ZA004 will be going to Everett to get some routine maintenance accomplished. This maintenance work was preplanned. ZA003 is expected to resume ground tests at Boeing Field. ZA001, ZA005 and ZA006 are also conducting ground tests until they all can have clearance to resume test flights.
Lastly, ZA102 which is the first production 787 to fly will be rolled out of 40-24 around the end of the month according to Guy. It would be fitted with the package "A" Trent 1000 engines and is schedule to fly in December depending on what happens with the fire investigation. Even if it doesn't fly it could still conduct ground test as well as taxi tests.
Guy Norris: 787 to fly again (briefly) on Saturday
Another 787 delay prediction, Scott Hamilton says 4 to 6 months
Still the panel and the electrical system would need to be redesigned but Boeing has a good handle on the scope of the work to be done. Additionally, Boeing is working with the FAA in order to resume flight testing while using a work around the panel issue and at the same time undertake the redesign of the the panel.
Scott Hamilton: Our 787 forecast: 4 - 6 month delay
FOD does seem (at this point) logical for the following reason: during the two plus years that the 787 first flight was delayed, Boeing and Hamilton Sundstrand had thoroughly tested the electrical system including the P100 panel in the Boeing systems lab in Seattle. There was no known occurrence of fire during those tests. As such because of the delays, many of the 787 systems have been thoroughly tested and are considered mature systems. Any issues that were uncovered during that time would have been corrected by now.
ATW: Boeing to announce 7th 787 delay
As I mentioned, the FAA is really the determinant of when the 787 will return to flight and be certified. At the time of the fire, I estimate that Boeing had about two and half to three months of flight testing to be completed. If this still holds then it's possible that the 787s could return to flight testing in about 6 months with delivery about 3 months later. This puts a projected first delivery date to about mid to late third quarter of 2011. I'm going to go out on a limb and say that Boeing will announce a new first delivery date of mid fourth quarter 2011. They will need some time to digest the data from the flight testing that has been done; produce the required engineering changes and incorporate the changes into the 787s that have been built.
Geoffrey Thomas: Boeing reportedly set to announce another 787 delay
Despite another delay, I expect that Boeing will continue to produce 787s and get them ready for delivery. As had been mentioned in the past postings, Boeing has significant rework to do on the 787s that have been built. Another delay will give them some breathing room to get that rework done. They will have more rework to do after the test flight fleet returns to the air and other issues are revealed that would require changes to be made on the production 787s. The continued production of 787 that are undelivered presents Boeing with another problem: where to put park all those 787s. Already Boeing is squeezing them into spots near the Future of Flight Museum as well as the the apron in front of the Boeing assembly building and has set aside spots near the Everett ATC Tower to park even more 787s. But if there is another delay where can Boeing park all those new built 787s especially as they attempt to ramp up production next year? Mind you that the Boeing Everett ramp will be full of 777, 747-8, and 787s. There is the potential of additional stalls to the south of the Boeing plant, as well as the ATS Hangar which Boeing is renting currently. Boeing can possibly rent the ramp space in front of the ATS hangar. Boeing can also use building 40-23 which was used for the static testing of the 787 fuselage. That fuselage is due to be removed as is the test equipment that was installed for the static testing.
According to sources, Boeing is looking into increasing the 777 production rate to 8 to 10 per month from the current 5.5 per month. Boeing would utilize 40-23 for additional 777 assembly space. However, with the current issues in the 787 program, that space might be better served, in the short run, to store production 787 as well as an enclosed space to do rework on the 787s. Hopefully many of the questions will be answered in the next few days.

What will drive another 787 delivery delay?
In my opinion, trying to read into something that is or isn't in a press release does smack of grasping at anything for information.
Is there a possibility of a delay?
Yes, a very real one. The fire was serious and had exposed some shortcomings in some of the systems that distribute electrical power through out the aircraft. No one knows what the problem is...yet. How long to fix it will be determined by the root cause of the fire, the fixes that needed to be implemented, and how to make sure that the insulation does not catch fire under any circumstance.
All that can be rectified but the driver of any delays won't be how long it'll take to fix any issues but the driver will be the FAA and any demands they place on Boeing to demonstrate that the power panels are safe and that there is very limited chance of fire in the aft bay and if there is a fire, that it is contained and doesn't damage any other vital systems. The other factor that Boeing will need to demonstrate (or re-demonstrate) is that the redundancies work as advertised. Boeing seemed to have been saying this yesterday though Heidi Woods was casting doubt about that in her research note.
When will the 787 return to flight? Only god and the FAA knows but we have to wait to hear the final results of the investigation before any educated judgement is rendered by those outside of the 787 program and the FAA.
