Boeing and the FAA continues on the certification flight test path with the test flight fleet accumulating just under 575 flight hours. Interestingly, flights that occurred yesterday were not posted on Flightaware for some reason and flight notifications are not being sent from Flightaware for any 787 flight.
Next week one 787 is going to fly to Colorado Springs Airport for more flight testing around May 11th. I surmise that this trip to Colorado might be for high altitude flight testing. ZA001 should return to flight test today or tomorrow and ZA002 will be flying towards the end of this week. ZA005 is still scheduled to make its first flight towards the end of May while ZA006 will follow by mid June.
Lastly, I have been keeping track of the 787 production and I found out that 4 of 5 787s for LN 26 to LN 30 will be going to Air India. LN 25 (ZA230), LN 26 (ZA231), and LN 28 (ZA232) to LN 30 (ZA234) will be for Air India. LN 27 (ZA178) will be a Japan Airlines bird. I expect that these airplanes will be in final assembly this fall.
