Aircraft Accident/Incident Report

Milwaukee, Wisconsin 53201
Thursday, August 9, 2001 21:15 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane experienced a partial loss of engine power, which was followed by a total loss of engine power while climbing through 200-300 feet agl from the departure airport. The pilot reported pushing the airplane down so as to land on a field with houses located in the direction of the landing path. The touchdown speed was reported by the pilot as being 90 mph. Five postaccident engine runs did not duplicate a similar loss of engine power. The top engine spark plugs were removed following the engine runs and were black and sooty in appearance. The engine driven fuel pump was removed and reported by the engine manufacturer to have a discharge pressure exceeding its maximum specified pressure.

NTSB Probable Cause Narrative

the rich fuel mixture and the unsuitable landing area encountered by the pilot. Contributing factors were the high output of the fuel pump and the low altitude.
