Following Nippon Airways decision to ground its fleet of 787’s earlier in the week, the Federal Aviation Administration has announced that all 787s in the United States are to be grounded also pending investigations into lithium-ion battery failures causing fires in both Japan and Boston. Air India have also temporarily halted flights of the 787 Aircraft whilst investigations are underway.
Todays announcement follows the news last week that the FAA have launched a full-scale investigation in the Dreamliner’s design, manufacture and assembly. In its short existence the Dreamliner has been fraught with problems including reported issues with the light-weight composite wings, oil leaks in the engines, various computer related issues, and of course now the battery fires.
The is the full FAA’s statement on the issue:
As a result of an in-flight, Boeing 787 battery incident earlier today in Japan, the FAA will issue an emergency air worthiness 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.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’s critical systems with the possibility of further action pending new data and information.
In addition to the continuing review of the aircraft’s design, manufacture and assembly, the agency also will validate that 787 batteries and the battery system on the aircraft are in compliance with the special condition the agency issued as part of the aircraft’s certification.
United Airlines is currently the only U.S. airline operating the 787, with six airplanes in service. When the FAA issues an air worthiness directive, it also alerts the international aviation community to the action so other civil aviation authorities can take parallel action to cover the fleets operating in their own countries.
Boeing Chairman, President and CEO Jim McNerney issued the following statement today after the U.S. Federal Aviation Administration (FAA) issued an emergency air worthiness directive;
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.
