Analysis

At 11,000 ft MSL during cruise a prop separated from the left eng. The eng was feathered & the plt observed the eng displaced inboard & downward. An emergency landing was made & upon landing the left main gear was found to be retracted. The acft slid to a stop coming to rest on the adjacent taxiway. Metallurgical examination revealed that the blade failed from fatigue initiating at corrosion pits on the interior of the failed blade balance hole. The paint in the balance hole was discontinuous & non-uniform. There was no evidence of the hole having been shotpeened. Overhaul instructions require shotpeening of the balance hole. TSO was calculated as 1565.8 hrs.
