Accident Overview
During the initial takeoff climb, the aircraft experienced a rough-running engine and a partial loss of power at approximately 600 feet above ground level, with a climb rate of 350 feet per minute. The aircraft was about 0.5 nautical mile from the departure airport when the power loss occurred. The available power was insufficient to maintain altitude.
Forced Landing and Ground Impact
The pilot conducted a forced landing to a field. During the landing, the aircraft touched down short of a fence that extended across the field. The aircraft struck metal fence posts, causing the nose gear to collapse. After impact, the aircraft skidded approximately 90 feet before coming to a stop.
Post-Accident Fire
After the aircraft stopped, a rear-seat passenger observed smoke emanating from the right side of the aircraft. The pilot and passengers evacuated through the left passenger door. Subsequently, the aircraft was consumed by fire.
Examination and Findings
Examination of the aircraft revealed that the fire was concentrated around the carburetor and the aft portion of the engine. However, the extent of fire damage precluded a determination of the cause of the partial loss of engine power.
Probable Cause
No probable cause was determined by the investigation.
