After departure from an asphalt runway, an airplane lost partial power during climb at about 400 feet. The pilot applied carburetor heat, but the airplane descended and impacted ground, coming to rest a quarter-mile from the runway. Post-accident engine test showed no abnormalities.

Overview

The accident occurred during the initial climb after takeoff from a 5,711-foot-long, 100-foot-wide asphalt runway. At approximately 400 feet above ground level, the airplane's engine experienced a partial loss of power, resulting in a descent and subsequent impact with the ground.

Sequence of Events

After completing warm-up and ground checks, the airplane departed. During the initial climb, at about 400 feet above the ground, the engine lost partial power. The airplane began to descend. Suspecting carburetor icing, the pilot applied carburetor heat. A few seconds later, the airplane struck the ground and came to rest approximately one-quarter mile from the end of the runway.

Pilot's Remarks

The pilot stated that a similar partial power loss had occurred several flights prior to the accident. He characterized that earlier event as isolated and attributed it to possible carburetor icing.
