Boeing Offers 787 Plan

Aircraft manufacturer Boeing has offered the US Federal Aviation Administration (FAA) a suggested solution to fix the 787 Dreamliner aircraft’s battery problems.

The worldwide fleet of 50 Dreamliners was grounded in January, following an emergency landing by All Nippon Airways (ANA) after a lithium-ion battery overheated on the aircraft.  Another battery fire had also occurred days earlier on a parked Japan Airlines 787 at Boston airport in the US.

Boeing’s plan of action includes use of a battery box aimed at insulating lithium-ion cells from one another to prevent their overheating, as well as a venting mechanism for fumes, the BBC has reported.

However, the measures are in response to inconclusive evidence, as no faults with the battery have been found by US National Transportation Safety Board inspectors, amid suggestions that the problems may have come from defects in the systems connected to the battery.  A separate Japan Transport Safety Board investigation has found that the overheated ANA battery was caused by an auxiliary power unit, which had been incorrectly connected.

Other issues to have dogged the Dreamliner include fuel leaks, faulty taping leading to cracks in the cockpit glass and braking difficulties.

United Airlines has removed the 787 from its flight schedule until June 5, while LOT Polish Airlines plans to keep the aircraft grounded until October.  ANA has also announced that its Dreamliners will not fly again until May.

As Airports International went to press, Boeing had not provided an official comment regarding its latest collaboration with the FAA.
