Thus far the 787 flight test fleet has accumulated over 406 test flight hours (through March 31st) spread over 134 flight. ZA001 has conducted most of the test flight as expected with ZA002 conducting the second most flights.
There is some concern amongst many followers of this program (including articles in the Wall Street Journal) that the 787 hasn't been flown enough to achieve the needed flight test hours for certification. Boeing has said that the test flight program will entail 3,100 flight hours spread across the 6 test airplanes. In order for Boeing to have the necessary hours by mid November which is 32 weeks from now (I picked mid-November as it will allow Boeing enough time to get the production 787 ready for customer delivery by Dec. 31, 2010...another 6 weeks) they would need to fly the test fleet at a clip of 82 hours per week starting now.
James Albaugh has stated that the 787 test fleet would be flying around 90 hours per week starting around the middle of this year. However, if Boeing is to meet it's 787 delivery target that it has set for itself, then it would need to start flying longer 787 sorties starting now. Currently, Boeing is averaging a little over 3 hours per flight through the 134 flights that have been conducted thus far. Boeing does plan on flying longer flights but that probably won't occur until the FAA has issued the Type Inspection Authorization that is needed to formally kick off the certification process. That was supposed to have happened by today as of the time I'm writing this post it has not occurred.
Flight Test Look Ahead
In the meanwhile, ZA001 continues to fly test flights. ZA002 is in the midst of upgrading it flight software to the Wedge 5.5 version that ZA004 had recently tested on the ground and in the air. This is the service-ready version of the 787 flight software. It is anticipated that ZA002 should be back in the air by the end of next week (around April 9th). Both ZA003 and ZA004 should both be flying again by Saturday, April 3rd. ZA005 is on the Boeing flightline, preparing for it's first flight and should be flying around May 8th. This will be the first flight of the GEnx-1B on the 787. The last flight test aircraft (also equipped with the GEnx-1B), ZA006, should be in the air by June 4th and is currently in building 40-24.
787 production continues apace with an important milestone taking place yesterday. LN 20 (ZA175), a 787 for Japan Airlines, started final assembly. This is the first weight optimized 787 to enter into final assembly and is introducing a major block point change with weight savings incorporated into the aircraft.
Boeing is slowly ramping up 787 production and the next aircraft LN 21 (ZA176) will enter final assembly around April 12th thus ZA 175 would be in position 1 for about 2 weeks before pulsing to the next assembly position. The dramatic reduction of traveled work (two words that hasn't been mentioned in some time) certainly has helped as well as the learning curve when it comes to assembling the 787s. Now the concern is managing the change incorporation process of the existing production 787s though Boeing does have a plan for that.

Hours after conducting the ultimate load test, Boeing announced that the test has been completed successfully based on preliminary examination of the data. It will be a few more weeks of detailed analysis by Boeing structural engineers. The wings were deflected to 25 ft high during the test. Once the data is analyzed by Boeing it will be sent to the FAA as part of the certification program. This is a huge hurdle that Boeing overcame especially in light of the side of body issue that was revealed over 6 months ago. Here's Boeing's press release:
Boeing Completes Ultimate-Load Wing TestThe next major milestone is the issuance of the Type Inspection Authorization (TIA) that will kick off the formal certification of the 787 by the FAA with their inspectors and engineers flying on board the 787 during the certification test flights. That is expected any day now, perhaps as early as tomorrow.
EVERETT, Wash., March 28, 2010 – Boeing today completed the ultimate load wing up-bending test on the 787 Dreamliner static test unit. During the testing, loads were applied to the airframe to replicate 150 percent of the most extreme forces the airplane is ever expected to experience while in service. The wings were flexed upward by approximately 25 feet (7.6 meters) during the test.
Initial results of the ultimate load test are positive. More extensive analysis and review are required before the test can be deemed a success.
“The test program has been more robust than any conducted on a Boeing commercial jetliner,” said Scott Fancher, vice president and general manager of the 787 program, Boeing Commercial Airplanes. “It has taken countless hours of hard work by the Boeing team and our partners to work through the static test program. Everyone who has been involved in this effort over the past several years should be very proud of their contributions to ensuring the safety of the 787 Dreamliner.
“We are looking forward to the technical team’s report on the details of the test results,” said Fancher. It will take them several weeks to work through all of the data.
During each second of the more than two-hour test, thousands of data points were collected to monitor the performance of the wing. Key data points are monitored real-time during the test, but all of the data will be evaluated in the weeks ahead.

The aircraft, ZA175, is destined for Japan Airlines with GEnx engines. The line will move on March 28 with LN 16 coming out and going to the paint hangar. Also on that day Boeing will hopefully be conducting the extremely important ultimate load test on ZY 997. Currently, Boeing is conducting tests on the static air frame in a build up to the ultimate load tests this Sunday. Mike Mecham of Aviation Week has a great blog post describing the ultimate load test.

The TIA will allow FAA inspectors and engineers on board the 787 for certification testing which starts after the issuance of the TIA. There is no word on when Boeing will receive the 787 TIA but it is expected before the end of this month.
Boeing had expected to complete this phase of the flight test program by mid February. Thus they are about a month and a half behind but still have some margin left in the flight test program schedule.
Certification testing is the longest part of the test flight program and will probably last until October or November depending on progress.

Autopia: Boeing 787 Completes Critical Flutter Testing
Randy's Journal : Flutter and ground effects
Monday, March 15, 2010
Three months into 787 flight testing Boeing is slowly ramping up the number of airplanes to the test flight fleet with the recent addition of ZA003 to the test flight program yesterday. However, through three months since ZA001 took flight, the program has accumulated just shy of 307 flight hours spread across 101 flights and 4 test airplanes.
Boeing has indicated that the program will need 3,100 flight hours (3,700 ground test hours) for full testing and certification. Additionally, Boeing Commercial Airplane Group chief, James Albaugh, said that by mid year the test flight fleet will be flying about 90 hours per week on average.
Given the 307 hours already flown (not even 10% of the total needed) three months in, Boeing would need to fly another 2,793 hours. Assuming another 8 months for those flight test (taking us to mid November, 2010), then Boeing would need to fly about 350 hours per month on average or over about 88 hours per week across the test flight fleet.
Mind you that right now there are 4 test airplanes in the fleet with some planes flying less hours than others given the flight test assignments for each airplane. For example, ZA003 will log significantly fewer hours in the air due to the cabin testing it will be doing versus ZA001. Thus much of the flight testing would fall on ZA001, ZA002, ZA004 and the unflown ZA005. ZA005 won't be flying until early May and ZA006 won't be flying until early June according to sources. Thus if Boeing plans to deliver by the end of the 4th quarter (they would need time to flight test the production airplanes as well as incorporate any changes that are needed), they would need to get more aggressive with flight testing as they are flying, on average, about 96 hours per month granted that flight testing has ramped over of the months. Boeing has achieved 100 test flights in the 3 months since ZA001's first test flight.
In December, the 787 flight test program logged 18 hours and 57 minutes across 5 flights. That averages about 3 hours and 47 minutes per flight.
In January, the flight test team logged 47 hours and 23 minutes across 13 flights. That is an average of 3 hours and 38 minutes, slightly lower than December.
In February, the 787 was flying 136 hours and 40 minutes across 46 test flights. That is an average of 2 hours and 58 minutes of flying time which is dramatically lower than January.
Through the first 15 days of March, the test flight fleet has flown 103 hours and 50 minutes over 37 flights. This equates to an average of 2 hours and 49 minutes per flight....even lower than February.
Thus utilization of the test flight fleet has been decreasing since first flight. If Boeing hopes to certify and deliver the 787 then the aircraft test flight utilization has to dramatically increase.

Boeing Flight Test Group is getting areal workout today by sending the 4th 787 (ZA003) and the 2nd 747-8F (third 747-8 built) into the air today. First up was ZA003. This aircraft, which will test the aircraft's cabin systems and is equiped with a representative cabin layout, took off from Everett Field at 10:52AM PT and flew over eastern Washington State. ZA003 landed at Boeing Field about 1:52PM PT. It had been airborne for a little over 3 hours.
Boeing has released a press release about ZA003's first flight. Here's the press release:
News Release Issued: March 14, 2010 7:22 PM EDT
Fourth 787 Joins Boeing Flight-Test Fleet
EVERETT, Wash., March 14 /PRNewswire-FirstCall/ -- Boeing (NYSE: BA) has added the fourth 787 Dreamliner to its flight-test fleet with the completion of the first flight of ZA003. The airplane departed Paine Field in Everett, Wash., at 10:55 a.m. (Pacific time) and landed at 2:01 p.m. at Boeing Field in Seattle.
Captains Ray Craig and Mike Bryan piloted the airplane on its three-hour-and-six-minute flight. ZA003 is the final 787 with Rolls-Royce Trent 1000 engines to enter the flight-test program.
"We've done a significant amount of ground testing on the new systems on ZA003 in preparation for first flight. Engineering, manufacturing and flight operations have really pulled together as a team to enable first flight," said Craig. "It has been very rewarding to watch the Boeing team pull together in support of this milestone."
ZA003 is the only 787 in the flight test fleet that will include elements of the passenger interior features including cabin and crew support systems. The 787 is introducing new passenger amenities and provisions for a more comfortable flying experience. Among the new features are improved lighting, bigger stowage bins, larger windows with electrochromatic shades and redesigned lavatories with easier access.
In addition to demonstrating that the interior meets certification requirements, ZA003 will be used to conduct tests on systems, noise performance, flight-deck operations, avionics, electromagnetic effects, high-intensity radio frequency response and extended operations (ETOPS).
"The Boeing team is doing great work. We've established a good pace of accomplishment on the program," said Scott Fancher, vice president and general manager of the 787 program, Boeing Commercial Airplanes. "The priorities are clear and the entire team is focused."
In the meantime, while ZA001 and ZA002 have been flying test flight, ZA004 has been used as a ground test article, for the time being, for the "service-ready"version of the 787 software, according to Flightblogger. The software includes tweaks to correct issues found during test flights of the 787. The testing that ZA004 is required by the FAA prior to the issuance of the Type Authorization Inspection certficate that will allow FAA inspectors and engineers on the 787 for certification test. According to Flightblogger, ZA004 should return to the air by tomorrow and will do some more ground testings followed by more flight testing at Victorville. Additionally, Flightblogger revealed that ZA005 and ZA006 should be flying by the end of April.

Second Boeing 747-8 Freighter Completes First Flight
EVERETT, Wash., March 15 /PRNewswire-FirstCall/ -- A second Boeing (NYSE: BA) 747-8 Freighter, RC 522, successfully completed its first flight Sunday evening. The airplane took off from Paine Field in Everett, Wash., for a two-and-a-half-hour flight and landed at Boeing Field in Seattle.
Captain Kirk Vining was at the controls for the flight, with Rick Braun operating as co-pilot and Joel Conard serving as systems operator. The airplane reached an altitude of 27,000 feet (8,230 m) and an airspeed of 240 knots, or about 276 miles (444 km) per hour. It took off at 3:57 p.m. PDT and landed at 6:25 p.m.
"The airplane performed well on its first flight," said Andy Hammer, test program manager for 747-8. "It was a good start to a demanding flight-test program for this airplane."
This is the second of three 747-8 Freighters being used in the flight-test program. Each
airplane will be used for a specific set of tests, with this airplane focusing on community noise, environmental control systems and extended operation performance standards.
The airplane will begin its flight-test program at Boeing Field before transitioning to Palmdale, Calif.

ZA003 first flight window opens at 10AM PST on Sunday March 14th (I'll be away skiing so I won't be able to cover it).
ZA004 was expected to return to flight tests this week but now it's been pushed back due to more ground tests at Boeing Field. Still no word on when it'll return to the air. As you may recall, after first flight ZA004 is spending some time on the ground for flight test equipment installation and calibration as well as for further ground tests. Boeing really needs to get this airplane back in the air soon given the testing that has been assigned to it.
Lastly, Randy Tinseth got up two nice posts on it, one on ZA002 and the testing at Victorville as well as one one the747-8 flight testing. The last two 747-8F will both be in the air in the next five days.

Boeing 747-8 Freighter Achieves Initial Airworthiness Milestone
MOSES LAKE, Wash., March 11 /PRNewswire-FirstCall/ -- Boeing (NYSE: BA) has completed initial airworthiness testing on the 747-8 Freighter. This milestone enables test engineers to be on board during future flights and allows the remaining two 747-8 Freighter test airplanes to begin flight test.
"The airplane is performing as expected in the initial stages of flight test," said Mo Yahyavi, vice president and general manager of the 747 program, Boeing Commercial Airplanes. "That's a tribute to the men and women who helped design and build this airplane."
Since the first flight in early February, the program has conducted 13 flights, achieving several key accomplishments. Pilots have taken the airplane to an altitude of 30,000 feet (9,144 m) and a speed of Mach .65. The program has completed approximately 33 hours of flying. Initial stall tests and other dynamic maneuvers have been run, as well as an extensive checkout of the airplane's systems. Five different pilots have flown the newest Boeing freighter.
"This is a critical milestone in our test and certification plan," said Andy Hammer, test program manager for the 747-8, Boeing Commercial Airplanes. "With the addition of the other two airplanes in the near future, the test program will ramp up significantly. We will expand the flight envelope and demonstrate the airplane's capabilities."
In the weeks ahead, the 747-8 Freighter will reach an altitude of more than 43,000 feet(13,106 m) and a speed of Mach .97. Subsequent testing will push the airplane beyond expected operational conditions.
Flight testing will continue in the months ahead. All told, the 747-8 Freighter test program calls for approximately 3,700 hours of testing using three test airplanes. First delivery is planned for the fourth quarter of this year.
Boeing has secured 108 orders for the 747-8, 76 of which are orders for the new freighter. Cargolux, Nippon Cargo Airlines, AirBridgeCargo Airlines, Atlas Air, Cathay Pacific, Dubai Aerospace Enterprise, Emirates SkyCargo, Guggenheim and Korean Air all have placed orders for 747-8 Freighters.

ZA001 will be taking to the air today for another flutter test flight today.
Matt Cawby reported in a post that ZA102 (LN 9) has finished its side of body modifications that were done in the Everett flightline tent.
Matt Cawby's 787 Update - March 9
This aircraft will be moved in the next couple of days to building 40-24 to one of the 767 slant positions on the 767 final assembly line to finish reassembly activities. The aircraft that is there now, ZA005 (LN 5) will be moved out to the flightline. Speaking of which, Dreamliner 5 and Dreamliner 6 won't be making their first flights until the 2nd quarter so that mean we won't see the GEnx-1B airplanes up until April at the earliest. ZA530 (LN 10) will be moved into the flightline tent to begin its side of body modifications.
ZA002 has landed in Victorville for a few weeks of flight testing then it'll be back to Boeing Field.
Here's Boeing's press release:
News Release Issued: March 9, 2010 3:59 PM EST
Boeing 787 Begins First Flight-Test Operations Outside of Washington
VICTORVILLE, Calif., March 9 /PRNewswire-FirstCall/ -- The second Boeing (NYSE: BA) 787 Dreamliner, ZA002, landed at 10:53 a.m. local time today in Victorville, Calif. This marks the beginning of the first flight-test operations outside of Washington state for the program.
The airplane will be stationed at Victorville for approximately three weeks. The crew will conduct ground effects testing among other activities.
During ground effects testing, the pilots fly the airplane very close to the runway to gather data regarding the aerodynamic effects and performance of the airplane during the takeoff and landing phases of flight. Quantifying this performance is part of the certification requirements for all new airplanes.
"Victorville's airfield is the former George Air Force Base," said Randy Neville, chief pilot for ZA002. "There is ample ramp space for parking and plenty of on-site facilities. There is a long runway and plenty of level, clear land along the approach to the runway. We can operate there without disrupting air traffic control or other commercial aircraft."
A crew of more than 150 employees will be stationed at Victorville while the airplane is there.These include the flight test engineers and support personnel required to prepare the airplane for each day's flights and to monitor performance and test equipment.
"Our confidence in the reliability of this airplane grows day by day," said Scott Fancher, vice president and general manager of the 787 program. "Taking the airplane out of state for the first time is a big step, but one we're ready for."
- 787 should receive the TIA (Type Inspection Authorization) by the end of this month (March).
- Boeing right now putting out 2 787s per month will be up to 2.5 airplanes per month by August, 2010 and up to 10/month by end of 2013.
- ZA003 should fly this Sunday (confirms what I had reported earlier here)
- ZA001 reached speeds of around M0.97 (in a dive) during testing.
- Expects first 787 delivery from Charleston in 1st quarter 2012
- Boeing has used up some of the 787 flight testing contingency and had about one to one and a half months of contingency left in the test flight program.
- New 747-8 coming "on line" on March 15, 17 (this means that Initial Airworthiness Testing is complete by then so that the two remaining 747-8 test airplanes will be in the air next week).
In other news, ZA003 ran its engines yesterday on the Boeing flight line and should be conducting its gauntlet testing towards the end of this week followed by first flight on March 14th. ZA002 has departed this morning for Victorville where it will continue flight testing.
A bit of surprising news is Boeing's award of 747 LCF Dreamlifter operations from Evergreen International to Atlas Air.
Unsurprisingly, Evergreen International is upset but their contract was for 35 years but is renewable every 5 years and it was due for renewal this year. Here's an article focusing on Evergreen's reaction.
Also, unsurprisingly, Flightblogger is reporting that the LCF contract was given to Atlas as part compensation for the delays to the 747-8F, 12 of which Atlas has ordered. Atlas is due to take over LCF operations from Evergreen this September. Boeing will retain ownership of the 4 LCFs.

It is not known when or how long ZA002 will beat Victorville or if other 787s will be joining it but the certification test program has the 787 test fleet making trips away from Boeing Field at times.
Flightblogger : Roadtrip! 787 heading for Victorville this week.
Through today's test flights, the 787 fleet has racked up slightly over 250 test flight hours across the three plane test fleet. ZA00 s expected to return to the air very soon (possibly by the end of this coming week) and ZA003 is expected to take to the air for the first time around March 14th. ZA005 should follow soon after that.
Continuing the roadtrip theme, Guy Norris at Aviation Week is reporting on his blog that Boeing is seriously considering sending the 787 AND the 747-8 to the Farnborough Air Show this summer. It would the first time since 1982 that two new Being Commercial Air products would be featured at the air show. Of course, all this hinges on how well the test program goes for both these airplanes.
Guy Norris: Show Time!
Guy also reports on the upcoming trip for ZA002 to California as well as updates on the rest of the 787 flight test fleet. Of note is that ZA003 will have it's two day gauntlet test this week. This would corroborate a flight test date of March 14 for this airplane.
Guy Norris : 787 Heads South
Thursday, March 4, 2010
Seattle Times reporter Dominic Gates had a revealing interview with Boeing Commercial Airplane group head Jim Albaugh.
Here's the extended interview:
In it he says Boeing prefers to build its commercial airplanes in the Puget Sound region of Washington State but only if they can get labor peace from IAM and SPEEA. The prospects of labor unrest is what motivated Boeing to locate the second line to Charleston, SC. Also very revealing is that Boeing will now dial down the 787 business model for future aircraft programs and not outsource as much work as they did for the 787. This will include the design, testing and production of the wings. Boeing will return more of the engineering in house for parts of the aircraft such as flight controls, composite fuselage and the wings. The outsourcing was driven more by business decision making rather than engineers making those decisions.

Dominic Gates' Interview with James Albaugh
Monday, March 1, 2010
Dreamliner 1 continues to rack up the most flight hours and mos flights with 39 flights that has accumulated almost 138 flight hours through March1, 2010. The 787 test fleet has accumulated almost 210 flight hours.
Boeing also started assembly of Dreamliner 18 after line move yesterday. Look for Boeing to start assembly on LN 19 and LN 20 (I don't have the ZA numbers yet). The later aircraft is an important milestone as it is a new block point that incorporates weight saving measures in an effort to lower the weight of the airplane. The 787-8 is still overweight but Boeing still hopes to find further areas where they can take out weight as the flight testing progress.
Because of the addition of ZA004 to the test program, Boeing will have valuable data to finalize the design of the 787-9 which is the stretched version of the 787-8. The -9's wing will be the same as that of the 787-8 but Boeing is hoping that test flight information from ZA004 flight tests will yield important information when designing the 787-9. Flightblogger has a blog post up tonight describing the 787-9 progress to date. In the article he says that the first 787-9 will be designated ZB001 but will be LN 139.
Flightblogger: Driving Forward on the 787-9 design
Guy Norris also put up an update on the 787 flight testing as well as the 747-8 flight testing. Guy sasy that ZA001 has flown 11 flutter tests (now 12) while ZA002 continues with stability and control flight testing. ZA003 should also start the run up to gauntlet testing next week.
