Airworthiness Directives; Agusta S.p.A. (Agusta) Model A109E Helicopters

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to Agusta Model A109E helicopters, that currently requires inspections of the exhaust ejector locking system, clamp, and dampers for each engine. The existing AD also requires verifying the torque of the metallic clamps and installing safety wire on the metallic clamps; inspecting and modifying the ejector saddles and the locking metallic clamps; and inspecting the metallic clamps, locking mechanisms, and dampers. This action would require modifying the engine exhaust ejectors. This proposal is prompted by the development of a kit to modify the engine exhaust ejectors to provide terminating action from the requirements of the current AD. The actions specified by the proposed AD are intended to prevent loss of the metallic clamp or the engine exhaust ejector, damage to the main or tail rotor system and subsequent loss of control of the helicopter.
