Reports of Latently Failed Fuel Shutoff Valves Discovered During Fuel Filter

Replacement

This AD was prompted by reports of latently failed fuel shutoff valves discovered during fuel filter replacement. We are issuing this AD to detect and correct latent failures of the fuel shutoff valve to the engine and auxiliary power unit (APU), which could result in the inability to shut off fuel to the engine and APU and, in case of certain fires, an uncontrollable fire that could lead to structural failure. Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to add airworthiness limitation numbers 28-AWL-ENG, 28-AWL-MOV, and 28-AWLAPU, by incorporating the information specified in the AD. The initial compliance time for accomplishing the actions specified is within 10 days after accomplishing the maintenance or inspection program revision as detailed above.
