Airworthiness Directive · Amendment 39-10619 · Agusta S.p.A. Model A109C and A109K2 Helicopters
Agusta S.p.A. Model A109C and A109K2 Helicopters
Model A109C and A109K2 helicopters, with tail rotor blades (blades), part number (P/N) 109-8132-01-107, serial number A5-all dash numbers, installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to Agusta S.p.A. (Agusta) Model A109C and A109K2 helicopters. This action requires a one-time inspection of each tail rotor blade (blade) for debonding, and if debonding exists which exceeds certain limits, replacement of the blade with an airworthy blade. This amendment is prompted by two incidents in which helicopters lost a blade tip fairing during ground run-up. The actions specified in this AD are intended to prevent loss of the tip fairing on a blade, which could result in increased vibrations, loss of the tail rotor assembly, and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
