Airworthiness Directive · Amendment 39-13352 · Hartzell Propeller Inc. Model HC-A6A-3 Series Propellers.
Hartzell Propeller Inc. Model HC-A6A-3 Series Propellers.
This AD applies to Hartzell Propeller Inc. model HC-A6A-3 series propellers with A10460 series composite blades installed. These propellers are installed on, but not limited to, Short Brothers Ltd. SD3-60 Series airplanes.
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. model HC-A6A-3 series propellers with A10460 series composite blades. This AD requires initial and repetitive visual inspections of A10460 series composite blades for cracks. This AD is prompted by reports of cracks in propeller blades, including an in- flight separation of a blade that caused damage to the airplane. We are issuing this AD to prevent separation of the propeller blade due to possible fatigue failure, which could result in damage to the airplane and possible loss of control of the airplane.
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.
