Aircraft Accident/Incident Report

Coopersville, Michigan 49404
Saturday, August 23, 1997 10:45 EDT

NTSB Narrative Summary Released at Completion of Accident

Following an agricultural flight, the pilot noticed that the right fuel tank was reading under 1/8 full and the left fuel tank was 1/4 full. The pilot opened the overflow valve and slipped the airplane to balance the fuel levels. The pilot did this maneuver twice and the fuel gauge indicated 1/8 full in both tanks. The pilot said that the fuel pressure was then lost and a total power loss occurred. He tried the regain fuel pressure by using the wobble pump but could not restart the engine. The airplane was moved and disassembled by the owner before the fuel tanks could be inspected. The owner said that the airplane manufacturer said fuel feed problems are caused by an air leak in the cover plates on the fuel tanks. The pilot did not dump his chemical load following the loss of engine power.

NTSB Probable Cause Narrative

the pilot inadequate fuel system management which led to a fuel starvation.
