Boeing sets up for 787 battery flight test


Boeing is on the verge of flight testing the modified 787 battery system changes on Line Number 86, an aircraft destined for LOT Polish Airlines. The aircraft is set to undergo a final pre-flight ground test in the afternoon (Pacific time), at Paine Field, Everett on 24th, and if all goes to plan could be cleared for a standard ‘B2’ profile, customer acceptance type flight test on March 25.

Flight tests will take place using SP-LRC, a sistership to this LOT 787 seen at Everett (Joe Walker)

Boeing originally hoped to conduct this flight test on either the 23rd or today, but evidently is working its way through last minute issues before conducting the flight test. Ground tests of the electric and electronic equipment (E/E) bay are also underway on a Japan Airlines 787 at Paine Field, though it is not known if these are directly associated with the on-going certification efforts for the battery modification, or simply part of the regular pre-delivery tests as Boeing gets set to resume production flight testing.

At Boeing Field, close to Seattle, the company is also preparing 787 development test aircraft ZA005 for ground tests of the revised battery – particularly the new stainless steel enclosure and its associated venting system. No date yet on when this might occur, though recent activity indicates the test may be scheduled for early in the week.
