What happened
During the takeoff and climb phase, while at an altitude of approximately 300 feet above ground level, the aircraft experienced an abrupt loss of engine power. The pilot reported that there was no preceding backfiring from the engine. In response to the power loss, the pilot attempted several emergency procedures, including switching fuel tanks, verifying that the electric fuel pump switch was in the on position, and confirming that the magnetos switch was set to both.
Following the loss of power, the aircraft impacted a down-sloping wooded area. The impact resulted in substantial damage to the airframe, specifically severing both wings and the stabilizer surfaces from the aircraft.
The investigation
An examination of the cockpit revealed that the flap handle was set to the 0-degree position, the ignition switch was in the both position, and the fuel selector was positioned on the left fuel tank.
Mechanical inspection of the wreckage confirmed the presence of fuel within the lines leading to the engine-driven pump. Investigators also verified cylinder compression, engine continuity, and electrical continuity within the ignition system. No anomalies were identified regarding the engine-driven fuel pump or the servo. However, the pilot noted that he did not recall performing the preflight checklist item regarding draining the fuel sumps prior to departure.
