What happened
During the takeoff phase from a 4,200-foot runway, the aircraft's engine lost power at approximately 250 feet above ground level. At this moment, the aircraft was positioned roughly halfway down the runway strip. The pilot immediately applied carburetor heat and deployed full flaps, intending to land on the remaining runway surface. Upon touchdown on the packed, snow-covered pavement, the engine regained power momentarily. However, the pilot determined there was insufficient runway distance to stop before striking a hard-packed, 10-foot-high snowbank. Consequently, the decision was made to execute a go-around.
During the climb-out phase, the engine lost power once more. The pilot was unable to return to the runway for a successful landing. The aircraft subsequently crash-landed in a snow-covered clearing located near a dump site on wooded, hilly terrain.
The investigation
A post-accident examination revealed no pre-crash mechanical discrepancies with the airframe or systems, except that the annual inspection was overdue. An operational check confirmed the engine ran satisfactorily. The carburetor was disassembled and inspected for contamination. Investigators found a very small piece of ice within the component. It was noted that water may have entered the system due to melting snow in the impact area.
Findings
The primary contributing factor was ice accumulation in the carburetor, which caused intermittent power loss. The pilot's decision to attempt a go-around after touchdown on a snow-covered runway with limited remaining distance contributed to the severity of the outcome. The overdue annual inspection status was noted but did not explain the immediate mechanical failure.
Safety message
Pilots operating in snowy conditions should be vigilant for carburetor ice, even during takeoff. Regular maintenance adherence is critical to ensure all systems are functioning correctly prior to flight.
