WASHINGTON (Reuters) – U.S. aviation regulators have issued an updated directive regarding a cracking issue with all of Boeing’s 777 model airplanes, according to a notice posted online on Tuesday.
The Federal Aviation Administration’s superseding airworthiness directive “was prompted by a report of a crack found in a front spar lower chord,” it said in the Federal Register notice. Errors in the earlier directive also “introduced a new unsafe condition related to the application of certain fastener cap seals,” it said.
Representatives for Boeing and the FAA could not be immediately reached for comment.
