(Reuters) - The U.S. Federal Aviation Administration has issued an airworthiness directive on a series of CFM International Inc turbofan engines made with a certain high-pressure turbine stator case installed.
FAA said the order follows the discovery of a quality escape at a manufacturing facility involving unapproved welds on high-pressure turbine cases and requires affected cases to be removed from service and replaced with an eligible part within 30 days.
CFM was not immediately available to comment.
