Airworthiness Directives; Eurocopter France Model AS332C, L, L1, and L2 Helicopters

摘要

This document proposes adopting a new airworthiness directive (AD) for Eurocopter France Model AS332C, L, L1, and L2 helicopters. This proposal would require inspecting the cockpit pedal unit adjustment lever (lever) for a crack at specified time intervals by either a borescope or by a dye-penetrant inspection and replacing any cracked lever with an airworthy lever before further flight. This proposal is prompted by reports of cracks detected in the lever. The actions specified by the proposed AD are intended to prevent failure of the lever, loss of access to the brake pedals on the ground or loss of yaw control in flight, and subsequent loss of control of the helicopter.
