Airworthiness Directive · Amendment 39-12407 · Agusta S.p.A. Model A109E Helicopters
Agusta S.p.A. Model A109E Helicopters
Model A109E helicopters, with tail rotor blade (blade), part number (P/N) 109-8132-01-107 or -109, installed, certificated in any category.
This amendment supersedes an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E helicopters that currently requires visually checking and inspecting each tail rotor blade (blade) for a crack at specified intervals. That AD also requires replacing any cracked blade with an airworthy blade. This amendment contains the same requirements but adds another blade to the applicability. This amendment is necessary because the added blade is manufactured using the same process as the blade that failed. The actions specified by this AD are intended to prevent failure of a blade 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.
