Airworthiness Directives; Eurocopter France Model AS 332C, L, L1, and L2 Helicopters

摘要

This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter France Model AS 332C, L, L1, and L2 helicopters. That AD requires conducting a filter clogging warning test, and, if necessary, replacing a jammed valve with an airworthy valve. This amendment requires the same actions as the existing AD but references a revision to the previously referenced service information; adds fuel filter part numbers to the applicability; and clarifies other provisions throughout the AD. This amendment is prompted by jammed fuel filter by-pass valves. The actions specified by this AD are intended to prevent power loss due to fuel starvation, engine flameouts, and a subsequent forced landing.
