We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This proposed AD was prompted by reports of latently failed fuel shutoff valves discovered during fuel filter replacement. This proposed AD would require doing an inspection to identify the part number of the engine fuel spar motor- operated valve (MOV) actuators; replacing certain MOV actuators with new MOV actuators on both airline information management system (AIMS) V1 and V2 equipped airplanes, or installing a newer software version on AIMS V2 equipped airplanes. We are proposing this AD to prevent latent failure of the fuel shutoff valve to the engine. This valve failure, if not prevented, could result in the inability to terminate fuel flow to the engine, which in case of an engine fire, could lead to wing failure.
