THE PILOT SAID THAT HE WAS IN CRUISE FLIGHT WHEN THE ENGINE SPUTTERED AND QUIT. HE LANDED ON A GOLF COURSE AND THE AIRCRAFT COLLIDED WITH TREES DURING THE LANDING ROLL OUT. RESPONDING FAA INSPECTORS REPORTED THAT THEY EXAMINED THE AIRCRAFT ON THE ACCIDENT SITE AND FOUND NO FUEL IN THE AIRCRAFT FUEL TANKS. HOWEVER, A FUEL LINE WAS RUPTURED NEAR THE BOTTOM OF THE FUSELAGE. AIRWORTHINESS INSPECTORS EXAMINED THE ENGINE AND FOUND NO MECHANICAL MALFUNCTIONS OR FAILURES. THE PILOT STATED THAT THE LOSS OF POWER WAS DUE TO A PARTIALLY BLOCKED FUEL VENT LINE, WHICH PREVENTED THE FUEL TANK FROM PROPERLY VENTING TO THE ATMOSPHERE.

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

FUEL STARVATION DUE TO A RESTRICTED FUEL TANK VENT LINE. CONTRIBUTING TO THE ACCIDENT WAS INADEQUATE MAINTENANCE.
