Boeing’s troubles with the battery system on its latest 787 Dreamliner aircraft have been well documented. Back in January the global fleet of 50 Dreamliner aircraft was grounded due to incidents caused by the batteries overheating. The manufacturer had been testing a new lithium-ion battery system and it is finally done with the certification testing process. The certification demonstration flight was completed on a line number 86 Dreamliner, a production airplane owned by Boeing and built for LOT Polish Airlines. The test flight had a crew of 11 on board which included two representatives of the Federal Aviation Authority.
The duration of this test flight was 1 hour and 49 minutes, it took off and landed after an “uneventful” flight at Paine Field in Everett, Washington. The manufacturer will now gather and analyze the data collected during the test flight. The required materials will be submitted to FAA. Boeing states that it is ready to reply to additional requests and continue in dialog with FAA so as to ensure that all of the Authority’s expectations have been met. A previous 787 functional test flight was conducted on the 25th of March.
