F.A.A. to Begin a Review of Boeing 787s
Jan 11th 2013, 12:54

Federal authorities said Friday they would order a review of electrical systems in Boeing's new 787 Dreamliner following a spate of incidents, including a battery fire earlier this week in Boston, 15 months after the technologically advanced aircraft came into service.

The Federal Aviation Administration said it would examine critical systems on the Boeing 787, including the design, manufacture and assembly of the aircraft. More details were to be announced at a news conference Friday in Washington with Transportation Secretary Ray LaHood; the administrator of the F.A.A., Michael Huerta; and Ray Conner, the head of Boeing's commercial airplane division.

The review comes amid an investigation by the National Transportation Safety Board into why a battery pack caught fire in a parked 787 at Logan International Airport in Boston on Monday. The fire occurred in a Japan Airlines plane from Tokyo after the passengers and crew had left the plane.

The battery, which powered the auxiliary power unit used when the plane is on the ground, sustained "severe fire damage," according to the N.T.S.B.

Earlier on Friday, All Nippon Airlines of Japan reported cracks in the cockpit window of a 787 Dreamliner heading from Tokyo to Matsuyama. A spokeswoman said it was the third time that cracks had appeared in the windshield of one of the 17 787s operated by A.N.A.; the other two incidents happened last year.

Boeing has delivered 50 of the 787 airplanes so far and has received orders for more than 800 of the planes. But since their first commercial flight in November 2011, some 787s have had electrical fires, fuel leaks or other problems.

The 787, which makes extensive use of lightweight carbon composites, also relies on electric systems more than previous generations of airplanes. Electrical systems, not mechanical ones, operate hydraulic pumps, de-ice the wings, pressurize the cabin and handle other tasks. The plane also has electric brakes instead of hydraulic ones.
