Abstract

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model A109C, A109K2, A109E, A109S, and AW109SP helicopters. This AD was prompted by a report of a crack on the tail rotor (TR) mast. This AD requires an inspection of certain TR sleeve assemblies for discrepancies, an inspection of certain TR shaft assemblies for discrepancies, a repetitive measurement of the position of the bushing of the TR sleeve assembly in relation to the pitch change slider assembly, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
