NTSB Investigating Japan Airlines Dreamliner Fire

The National Transportation Safety Board (NTSB) is investigating the cause of a fire in the underbelly of a Japan Airlines Boeing 787 Dreamliner at Boston's Logan International Airport on Monday.



According to airport officials, airline mechanics reported seeing smoke shortly after passengers exited the plane. Firefighters used a thermal imaging device to determine the fire was caused by battery in the auxiliary power unit in the underbelly of the plane that is only used when the plane is on the ground and engines are off.

The fire is the latest problem in a string of incidents involving mechanical and electrical issues with Boeing’s 787.

Back in July, NTSB investigated an engine failure on a 787 that occurred during preflight runway testing in South Carolina, and found the failure was the result of a fractured fan on the engine mid-shaft. In December, FAA issued an airworthiness directive requiring Boeing to inspect all in-service 787s for fuel leaks. Also in December, a United Airlines 787 made an emergency landing due a failed generator.

During an interview with CNBC in mid-December, Boeing CEO and Chairman Jim McNerney referred to the issues as “the normal number of squawks on a new airplane.” More
