Sunday, October 15, 1989 11:15 EDT

NTSB Narrative Summary Released at Completion of Accident

THE PLT WAS FERRYING THE ACFT TO HIS HOME BASE AFTER PURCHASING IT FROM A POLICE AUCTION. HE SAID THAT DURING A REFUELING STOP, HE NOTICED THE LEFT ENG USED MORE FUEL THAN THE RIGHT ENG. LATER, WHILE ON FINAL APCH TO RWY 24 AT POTOMAC AIRPARK, HE NOTICED HIS ALTITUDE WAS TOO HIGH, SO HE INITIATED A GO-AROUND. DURING THE GO-AROUND, THE LEFT ENG LOST POWER. THE PLT MADE A PRECAUTIONARY LANDING IN A FIELD ABOUT 180 FT PAST THE DEP END OF THE RWY & THE ACFT WAS DAMAGED. AN EXAM REVEALED THE LEFT MAIN & LEFT AUX TANKS WERE EMPTY. THE RIGHT MAIN TANK WAS 1/2 TO 3/4 FULL & THE RIGHT AUX TANK HAD A MINIMAL AMOUNT OF FUEL REMAINING. THE PLT STATED HE DID NOT CROSSFEED FUEL TO EITHER ENG DURING THE FLT.

NTSB Probable Cause Narrative

THE PILOT'S IMPROPER USE OF HIS FUEL SUPPLY, WHICH RESULTED IN FUEL STARVATION AND LOSS OF POWER IN THE LEFT ENGINE. A FACTOR RELATED TO THE ACCIDENT WAS THE PILOT'S LACK OF FAMILIARITY WITH THE AIRCRAFT.
