Event Summary
The pilot reported that after takeoff, the landing gear was retracted and the aircraft climbed to approximately 100 feet above ground level. At that point, the engine suddenly lost power. The pilot extended the landing gear to perform a forced landing on the airport. Upon touchdown, the nose landing gear had extended and locked, but the main landing gear were only partially extended. The pilot was unable to maintain directional control, and the airplane skidded off the runway.
Post-Accident Examination
Following the accident, an examination of the aircraft revealed two discrepancies. The engine-driven fuel pump could not produce its rated pressure at high power settings. Additionally, a hole was found in the upper deck reference line, which had been caused by chafing against the generator mounting bracket.
