Boeing announced that the first 787 built in North Charleston will roll out of final assembly on April 27th. This aircraft, ZA237 (L/N46), is destined for Air India and should be delivered this summer. Even though it is rolling out it will probably go through a more extensive battery of ground and gauntlet testing as this is the first 787 built outside of Everett where most of the assembly technicians are new to building this aircraft. After gauntlet testing Boeing will conduct a B-1 test flight and then fly the aircraft to Texas where it will be painted. It will return to North Charleston to finish pre-delivery Boeing and customer test flights. I don't know if it already has the customer interior installed but that could happen just before painting but after flying the initial test flight. In case the test flight has uncovered any issues that need to be corrected, Boeing techs will probably want unrestricted access to any areas. Interior fittings like seats, galleys, and restrooms can get in the way.
Lastly, I updated the 787 production firing order with LN71-LN75. One slight change is that LN 63 which was going to be for Hainan Airlines is now going to ANA with Hainan now getting LN 73. I was able to get some information on where these particular airplanes will be built as well. These 5 frames are, for now, scheduled to go to Ethiopian (2 frames), Air India, Hainan, and LAN. Interesting no new first delivery frames in this lot.
