THE CERTIFICATED PRIVATE PILOT AND A PASSENGER DEPARTED IN A TWIN ENGINE AIRPLANE ON A LOCAL FLIGHT AND WERE REPORTED OVERDUE. WITNESSES INDICATED THAT THE LEFT ENGINE WAS NOT PRODUCING FULL POWER. THE AIRPLANE WAS LOCATED THE FOLLOWING DAY ABOUT 22 MILES FROM THE DEPARTURE AIRPORT. BOTH OCCUPANTS WERE FATALLY INJURED. THE INVESTIGATION REVEALED THAT THE AIRPLANE WAS UNAIRWORTHY. THE LEFT ENGINE PRIMER WAS NOT LOCKED AND AUTOMOTIVE GASOLINE WAS UTILIZED IN THE AIRPLANE. THE PILOT INTENTIONALLY SECURED THE ENGINES AND FEATHERED THE PROPELLERS. THE AIRPLANE STRUCK THE GROUND WITH LITTLE FORWARD SPEED, AT A HIGH VERTICAL DESCENT RATE, IN A NOSE DOWN AND NEAR WINGS LEVEL ATTITUDE. THE PILOT DID NOT POSSESS A CURRENT MEDICAL CERTIFICATE OR A MULTIENGINE RATING. THE PILOT'S RECENCY OF EXPERIENCE COULD NOT BE DETERMINED. TOXICOLOGICAL TESTING REVEALED THAT THE PILOT AND PASSENGER HAD ALCOHOL PRESENT IN THEIR BLOOD.
Probable Cause: THE PILOT'S POOR JUDGEMENT IN THE OPERATION OF THE AIRPLANE WITH KNOWN DEFICIENCIES AND THE INADVERTENT STALL DURING A FORCED LANDING. THE PILOT/OWNERS LACK OF MAINTENANCE ON THE AIRPLANE AND THE PILOT'S IMPAIRMENT BY ALCOHOL WERE FACTORS IN THE ACCIDENT.
