Airworthiness Directive · Amendment 39-18179 · Main rotor blades
Agusta S.p.A. (Agusta) Helicopters
This AD applies to Model A109A helicopters, serial numbers (S/N) 7154 through 7255, and all Model A109A II helicopters, with a main rotor blade (blade) part number (P/N) 109-0103-01-7 installed, certificated in any category.
We are publishing a new airworthiness directive (AD) for Agusta Model A109A and A109A II helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires replacing a certain part-numbered blade with an approved part- numbered blade. This AD is prompted by an error in the Illustrated Parts Catalog (IPC) that incorrectly allows installation of a certain part-numbered blade on the affected helicopters. These actions are intended to prevent blade failure and subsequent loss of control of the helicopter.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Before further flight, replace each blade with blade P/N 109-0103-01-9 or 109-0103-01-115.
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.
