Information just received indicates that while Boeing will be preparing 787s for delivery including the first deliveries of the GEnx-1B powered 787s. However, none of these airplanes will be delivered this month. It looks like these airplanes are being delayed about three and a half weeks.
According to information just received, ZA117 (JA806A, L/N 40) will be delivered to ANA around March 14th. This aircraft just had its first flight on Feb. 7. Both JA177 (JA822J, L/N 23) and ZA179 (JA825J, L/N 33) are scheduled to be delivered to Japan Airlines around March 24 with ZA179 tentatively scheduled to make its first flight around Feb. 13th (ZA177 had its first flight last year).
Lastly, ZA105 (JA808A, L/N 42) is scheduled to make its first flight around Feb. 29th but no delivery date has been set.
Undoubtedly this schedule shift has been caused by the need to check the aft fuselage for improper shimming installation and to take corrective measures if any are needed. Flightblogger has revealed that the inspections would take about three days but any work to correct any problems would take about two weeks per aircraft. This new schedule would corroborate this time estimate.
Meanwhile, Boeing contiues F&R/ETOPs testing on ZA236. On Wednesday/Thursday this aircraft flew a long 19 hour flight essentially Etch-A-Sketching "787" and the Boeing Corporate logo in the skies over the Western and Mid-Western sections of the country. Thus far this aircraft has flown 48.5 hours. It is expected that this airplane needs to fly about 150 hours to finish the certification program for the GEnx powered 787s.
