Incident Details
While the airplane was on final approach for landing, both engines experienced a loss of power. The pilot immediately moved the boost pump switches to the high position and switched the fuel selector valves to the auxiliary tanks, but these actions did not restore power. Recognizing that there was insufficient altitude to reach the runway, the pilot maneuvered the airplane to avoid some structures, but the aircraft subsequently collided with trees.
Investigation Findings
An investigation into the incident revealed that no fuel quantity indicators were installed in the airplane. Additionally, the main fuel tanks were found to be empty, while both auxiliary fuel tanks were full.
Aircraft Manual Specifications
According to the owner's manual, the auxiliary fuel supply was designated for use only during cruise flight. The manual further stated that if an engine or an engine-driven fuel pump failed, fuel would not be available from the respective auxiliary tank.
