Airworthiness Directive · Amendment 39-10289 · Hartzell Propeller Inc. Model HC-E4A- 3(A,I) Propellers
Hartzell Propeller Inc. Model HC-E4A- 3(A,I) Propellers
Hartzell Propeller Inc. Model HC-E4A-3(A,I) propellers with serial numbers HJ1 to HJ654, installed on but not limited to Raytheon Beech 1900D series aircraft.
This amendment adopts a new airworthiness directive (AD) that is applicable to Hartzell Propeller Inc. Model HC-E4A-3(A,I) propellers. This action requires replacing propeller blade counterweight clamp bolts with improved bolts. This amendment is prompted by reports of a manufacturing defect in the counterweight clamp bolts that resulted in the blade counterweight separating and causing damage to the propeller. The actions specified in this AD are intended to prevent counterweight clamp bolt failure, which can result in propeller blade counterweight separation and damage to the propeller and aircraft.
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.
