What happened
Thirty-four minutes after departure, the pilot experienced a total loss of power. The cause was identified as a blocked fuel vent system. During the subsequent forced landing attempt to an open field, the airplane collided with a barbed-wire fence before coming to rest.
The investigation revealed that the pilot did not possess a current medical certificate and had not received a current biennial flight review. Additionally, records indicated that the airplane had flown a total of only five hours in the last eight months prior to the incident.
The investigation
Examination of the event confirmed that the blocked fuel vent system was the primary mechanical factor contributing to the power loss. No other mechanical failures were cited in the factual narrative provided.
Findings
Contributing factors included the pilot's lack of current medical certification and failure to complete a required biennial flight review. The limited recent flight time for the aircraft may also be relevant context, though the direct cause was the fuel system blockage.
