Engine Power Loss During Takeoff Leads to Stall and Impact (N3714R)

Summary of Events

The pilot reported that during takeoff, the engine lost power as the aircraft was climbing through approximately 100 to 125 feet above ground level (AGL). He executed a right turn to return to the airport for landing. However, the aircraft stalled and subsequently impacted in a parking lot near the departure end of the runway. The aircraft caught fire and was consumed by flames.

Investigation Findings

The investigation found no evidence of preimpact part failure. Torsional damage to the propeller was noted, and propeller strike marks were identified at the initial impact point. The carburetor separated from the engine during the impact and was recovered outside the fire area, but it was close enough to the fire to sustain burn damage to the air filter. Examination of the carburetor revealed evidence of fire in the carburetor throat, which could indicate possible preimpact damage. However, the float chamber contained vent holes through which residual fuel could have escaped and fed the post-crash fire.
