The agricultural airplane was on final approach to a planned fuel stop during the cross-country flight when the accident occurred. About 3-4 miles from the airport, the engine temperature surged then decreased. The engine stopped running and the pilot decided to land in a field, resulting in substantial damage to the right wing. Examination of the airplane revealed a kinked rubber fuel vent line in the right wing. The line was creased across a structural beam, which restricted the air flow to the fuel tank. Just before the accident flight, the airplane was at a maintenance facility for repairs. During the repairs, the wings had been removed and replaced. The right wing’s fuel vent line was not installed properly. This most likely resulted in an air blockage and drop in fuel pressure as the fuel quantity was reduced during the 2.5-hour flight, resulting in the loss of engine power.
