## Abstract

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.
