Incident Overview
During a flight, at an altitude of 200 feet above ground level, following a touch-and-go landing, the aircraft suffered a total loss of engine power. The pilot conducted a forced landing, which resulted in the aircraft coming to rest on rough and uneven terrain.
Examination Findings
Subsequent examination of the aircraft provided evidence that the left fuel tank, which had been selected, had a totally blocked fuel vent. The blockage was caused by a mud-based insect nest located internally within the vent. The nest could not be seen during normal inspection due to its internal position.
Additional Context
The aircraft had not been flown in the 20 days prior to the accident flight. No other factors were identified in the examination.
