Probable cause
The pilot’s failure to use carburetor heat, which resulted in fuel starvation during the initial climb, a loss of engine power, and impact with terrain.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot was practicing touch-and-go landings on a private grass airstrip when he experienced a loss of engine power during initial climb. The airplane then descended and impacted terrain near the departure end of the runway. The airplane sustained substantial damage to the left wings. Postaccident examination of the airplane revealed no mechanical anomalies that would have precluded normal airplane operation. Serious carburetor icing conditions at glide power were present at the time of the accident. The pilot stated that he did not use carburetor heat during the flight. Carburetor icing most likely formed during the preceding descent for landing and remained for the accident takeoff.
