BOEING STATEMENT ON FIRST ROUND OF BATTERY MONITORING TESTS
(The following is a reformatted version of a statement issued by Boeing and received via electronic mail. The statement was confirmed by the sender.)
Capt. Mike Bryan, Capt. Randy Neville and a crew of 11 flight test personnel completed the first round of battery monitoring tests today on board ZA005, the fifth 787 flight test airplane, with a one hour and 29 minute flight. The flight departed from Boeing Field at 10:17 am Pacific time and returned to Boeing Field at 11:46 am Pacific time. The pilots report that today’s flight was uneventful.
This round of testing also included a flight on Saturday, which lasted 2 hours and 19 minutes. Analysis of the test results will continue in the days ahead.
During the flight, the crew monitored the performance of the main and APU batteries. Special equipment onboard ZA005, which is currently the only member of the Boeing 787 flight test fleet in service, allowed the crew to observe and record detailed battery performance in normal flight conditions.
Data gathered during the flight is considered part of the investigations into the 787 battery events that occurred in January. For that reason, we cannot share any additional details.
There are no additional flight tests planned for ZA005 at this time.
