This AD results from several reports on the affected airplanes of chafing damage on the left propeller accumulator oil tube assembly. This includes an in-flight oil leak from the left engine on a Raytheon Aircraft Company Model G58 airplane. We are issuing this AD to detect, correct, and prevent any chafing damage of the left propeller accumulator oil tube assembly, which could result in loss of engine oil. Loss of engine oil may lead to fire or smoke in the engine compartment, inability to unfeather the propeller, engine damage, or loss of engine power.
