Aircraft involved

Probable cause & findings

IMPROPER USE (MISMANAGEMENT) OF THE FUEL SYSTEM BY THE PILOT, WHICH RESULTED IN FUEL STARVATION. RELATED FACTORS WERE: THE LACK OF FUEL QUANTITY INDICATORS (NOT INSTALLED) IN THE AIRCRAFT, FLIGHT BY THE PILOT WITH THIS KNOWN DEFICIENCY, AND TREES IN THE EMERGENCY LANDING AREA.

Factual narrative

AS THE AIRPLANE WAS ON FINAL APPROACH TO LAND, BOTH ENGINES LOST POWER. THE PILOT IMMEDIATELY MOVED THE BOOST PUMP SWITCHES TO THE HIGH POSITION AND SWITCHED THE FUEL SELECTOR VALVES TO THE AUXILIARY TANKS, BUT TO NO AVAIL. REALIZING THERE WAS INSUFFICIENT ALTITUDE TO REACH THE RUNWAY, HE MANEUVERED THE AIRPLANE TO MISS SOME STRUCTURES, BUT IT COLLIDED WITH TREES. AN INVESTIGATION REVEALED NO FUEL QUANTITY INDICATORS WERE INSTALLED IN THE AIRPLANE AND THAT THE MAIN FUEL TANKS WERE EMPTY; HOWEVER, BOTH AUXILIARY FUEL TANKS WERE FULL. THE OWNER'S MANUAL STATED THAT THE AUXILIARY FUEL SUPPLY WAS TO BE USED IN CRUISE FLIGHT ONLY AND THAT FAILURE OF AN ENGINE OR ENGINE DRIVEN FUEL PUMP WOULD RESULT IN FUEL NOT BEING AVAILABLE FROM THE RESPECTIVE AUXILIARY TANK.
