During a flight to equalize fuel weight, the pilot switched tanks, causing engine power loss. Despite switching back and using a hand pump, the engine did not respond. The airplane landed in a swampy field and flipped over, sustaining substantial damage. Postaccident inspection found fuel in only one tank.

Accident Overview

The airplane was substantially damaged during a forced landing following a loss of engine power. According to a police report, the pilot stated that the engine quit while he was switching fuel tanks to equalize weight. He attempted to switch back to a different fuel tank, but the engine still did not respond. He also tried using the manual fuel hand-pump, with no response from the engine.

Landing and Damage

The pilot landed the airplane in a swampy field adjacent to a road. During the landing, the aircraft contacted the ground and flipped over. The airplane sustained substantial damage as a result of the forced landing and the subsequent rollover.

Postaccident Examination

A postaccident examination of the aircraft revealed no fuel remained in the left fuel tank or the auxiliary fuel tank. Approximately 2 inches of fuel remained in the right fuel tank when measured with a dipstick. No anomalies were found with respect to the aircraft or its systems, indicating that the engine failure was not due to a mechanical malfunction.
