Incident Overview
During a flight, the pilot reported that the engine progressively lost power. An emergency landing was initiated in a small clearing. However, the pilot was unable to bring the aircraft to a stop before it collided with trees at the end of the clearing. As a result, the pilot sustained a broken leg.
Investigation Findings
Following the incident, an investigation was conducted. No preimpact mechanical problem was found with the aircraft or engine. According to icing probability charts, meteorological conditions at the time were conducive for carburetor icing at cruise power. The charts indicated that the temperature and humidity levels were within the range where carburetor icing could occur under the given power settings.
Conclusion
The incident highlights the potential for engine power loss due to carburetor icing in conducive meteorological conditions. No other mechanical issues were identified.
