FAA Grounds 787 Dreamliners

The US Federal Aviation Administration (FAA) has grounded the Boeing 787 Dreamliner due to the mounting evidence of problems with the aircraft's lithium battery sub-system. The move follows an earlier announcement by the agency of a review of the Dreamliner's safety, design and the certification process that lead to its approval for air carrier operations.

The FAA said, "As a result of an in-flight, [sic] Boeing 787 battery incident earlier today in Japan, the FAA will issue an emergency airworthiness directive (AD) to address a potential battery fire risk in the 787 and require operators to temporarily cease operations. Before further flight, operators of U.S.-registered, Boeing 787 aircraft must demonstrate to the Federal Aviation Administration (FAA) that the batteries are safe."

The FAA will work with the manufacturer and carriers to develop a corrective action plan to allow the U.S. 787 fleet to resume operations as quickly and safely as possible, says the FAA.

Boeing issued the following statement in response to the FAA's emergency AD:

"The safety of passengers and crew members who fly aboard Boeing airplanes is our highest priority.

Boeing is committed to supporting the FAA and finding answers as quickly as possible. The company is working around the clock with its customers and the various regulatory and investigative authorities. We will make available the entire resources of The Boeing Company to assist.

We are confident the 787 is safe and we stand behind its overall integrity. We will be taking every necessary step in the coming days to assure our customers and the traveling public of the 787's safety and to return the airplanes to service.

Boeing deeply regrets the impact that recent events have had on the operating schedules of our customers and the inconvenience to them and their passengers."

According to the FAA statement, the in-flight Japanese battery incident followed an earlier 787 battery incident that occurred on the ground in Boston on January 7, 2013. The AD is prompted by this second incident involving a lithium ion battery. The battery failures resulted in release of flammable electrolytes, heat damage, and smoke on two Model 787 airplanes. The root cause of these failures is currently under investigation. These conditions, if not corrected, could result in damage to critical systems and structures, and the potential for fire in the electrical compartment.

Last Friday, the FAA announced a comprehensive review of the 787.
