NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE AIRPLANE HAD BEEN IN STORAGE FOR 10 YRS. IN MAY 1993, IT WAS REMOVED FROM STORAGE AND A CONDITION INSPECTION PERFORMED. THE ACCIDENT FLIGHT WAS THE SECOND SINCE REMOVAL FROM STORAGE. AFTER THE AIRPLANE WAS SEQUENCED FOR LANDING, THE LOCAL CONTROLLER HEARD A GARBLED TRANSMISSION FROM THE AIRPLANE CONCERNING THE ENGINE. NO FURTHER TRANSMISSIONS WERE HEARD. GROUND WITNESSES REPORTED THAT THE AIRPLANE APPEARED TO BE ATTEMPTING TO LAND ON A RESIDENTIAL CITY STREET WITH THE PROPELLER STOPPED. IT THEN COLLIDED WITH 3 TREES, A PARKED PICKUP TRUCK, AND THE STREET. FIRE CONSUMED THE AIRPLANE. THE FIRE DEPARTMENT DRAINED ABOUT 10 GALS OF FUEL FROM THE FUSELAGE TANK AFTER THE FIRE WAS EXTINGUISHED. THE DRAINED FUEL HAD AN ODOR AND COLOR SIMILAR TO AUTOMOTIVE GASOLINE. THE ENGINE WAS SUBSEQUENTLY INSTALLED ON A TEST STAND AND RUN FOR 4 MIN 40 SECS. MAGNETO CHECKS WERE SATISFACTORY, AND THE ENGINE RESPONDED WELL TO RAPID THROTTLE MOVEMENTS.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON(S). A FACTOR IN THE ACCIDENT WAS THE UNSUITABLE NATURE OF THE TERRAIN ENCOUNTERED DURING THE FORCED LANDING.
