Hartzell Propeller Inc. Models HC-B5MP-3C/M10876K Propellers
This AD applies to Hartzell Propeller Inc. Model HC-B5MP-3C/ M10876K propellers. These propellers are installed on, but not limited to, Short Brothers Model SD3-60 airplanes.
The FAA is superseding an existing airworthiness directive (AD) for Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers, installed on Short Brothers Model SD3-60 airplanes. That AD currently requires initial and repetitive removal, disassembly, inspection, and rework if necessary of Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers until blades are replaced with new design blades, no later than March 31, 1988. This ad requires installation of new design blades before further flight, on Hartzell Propeller Inc. Models HC-B5MP-3C/ M10876K propellers. This AD supersedure is prompted by a review of all currently effective ADs, which found that AD 87-16-02 was not published in the Federal Register to make it effective to all operators, as opposed to just the operators who received actual notice of the original AD. We are issuing this AD to prevent propeller blade separation near the hub, which could result in engine separation from 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.
