WPR12LA182

The pilot, who did not hold a repairman or mechanic certification, reported that he had been replacing the fuel lines. About 1 hour into the flight, the engine lost power, and the pilot initiated a forced landing in a field. During the landing roll, the airplane nosed over. Postaccident examination of the airplane revealed that the fuel lines were secured with tie wraps. The tie wraps secured the lines in an oval shape, which could introduce air into the fuel system and result in a loss of engine power. No additional mechanical malfunctions or failures were found that would have precluded normal operation.
