Analysis

The acft went off the rwy and collapsed the landing gear after power loss during takeoff. Three of the passengers furnished statements and 2 seemed to think that the left engine quit. The acft turned to the right but the pilot did notknow which engine quit. After the accident the left propeller blades were in feather but all the stops were broken. The right prop blades were bent but in high pitch. During a later test run the right engine produced 48 inches of manifold pressure but the left produced only 40 inches. The right engine had an oil leak dripping onto the turbo-charger. The push rod covers were covered with a silicone sealant.
