Boeing operated a 787 test flight Monday, though it was unrelated to the battery issue that has grounded the worldwide Dreamliner fleet.
Boeing last week conducted a test flight as part of its effort to gain FAA certification for its revamp of the 787’s battery system, and will conduct a second such flight “in the coming days,” the manufacturer said in a statement. Monday’s flight to/from Paine Field in Everett, Wash., was conducted with a production aircraft designated for LOT Polish Airlines and was “a routine test flight designed to address ongoing system upgrades to the airplane,” Boeing said.
The Seattle Times reported that Monday’s test flight was related to new power panels for the aircraft. Boeing late last year was contending with power distribution panel issues on several 787s, but those problems were overshadowed by the lithium ion battery failures on two in-service 787s in January.
