Agusta S.p.A. Model A109E Helicopters
Model A109E helicopters, certificated in any category.
This amendment adopts a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) helicopters that requires establishing or reducing the life limits of various parts listed in the airworthiness limitations section (ALS) of the maintenance manual. This amendment is prompted by the results of fatigue tests and analysis to determine life limits for various parts. The actions specified by this AD are intended to establish or reduce the life limits to prevent failure of specified parts 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.
