Aircraft Accident/Incident Report

Lone Rock, Wisconsin 53556
Saturday, November 4, 1995 13:08 CST

NTSB Narrative Summary Released at Completion of Accident

THE PILOT REPORTED THAT HE HAD DEPARTED RUNWAY 27, AND AT 400 FEET ABOVE GROUND LEVEL, JUST AFTER HE HAD RETRACTED THE LANDING GEAR, THE ENGINE HAD A LOSS OF POWER. HE REPORTED THAT HE MADE A 180 DEGREE LEFT TURN TO DOWNWIND TO RETURN TO THE RUNWAY. WHEN HE REALIZED THAT HE WAS NOT GOING TO REGAIN POWER, HE MADE ANOTHER LEFT TURN TO TRY TO LAND ON THE RUNWAY. THE AIRCRAFT IMPACTED A FIELD LEFT WING FIRST AND CAME TO REST ABOUT 20 FEET BEYOND THE INITIAL ENGINE IMPACT. THE PILOT STATED THAT THE STALL WARNING WAS SOUNDING DURING MUCH OF HIS ATTEMPT TO RETURN TO THE RUNWAY. THE RUNWAY WAS SURROUNDED BY FLAT PLOWED FARM FIELDS. AN INSPECTION OF THE AIRCRAFT AND ENGINE SYSTEMS, EXCEPT FOR THE FUEL INJECTION UNIT WHICH WAS DESTROYED, REVEALED NO DEFECTS.

NTSB Probable Cause Narrative

a partial loss of engine power for an undetermined reason, and the pilot's failure to maintain airspeed during his attempt to land the airplane back on the runway. A factor in the accident was the pilot's decision not to land in the suitable fields surrounding the airport.
