This AD results from reports of in-flight engine shutdown caused by uncommanded operation of the feather pump of the propeller. We are issuing this AD to prevent uncommanded feathering of the propeller, which could result in the shutdown of an engine during flight and consequent reduced controllability of the airplane.
