The U.S. Federal Aviation Administration plans to add Boeing Co.’s widely used 747 to the list of airplanes that must have their cockpit windows inspected or replaced because of the danger of an electrical fire, the Associated Press reported Thursday.
The FAA, set to publish its proposed order Friday, issued a similar directive for other Boeing planes in July. The window heaters on some planes have had electrical arcing or open flames. Boeing has acknowledged at least 29 incidents since 2002. Some of them led to forced landings.
The proposed order would cover 251 U.S.-registered 747s. The FAA estimates that each inspection cycle would cost airlines that operate 747 planes $5.4 million.
