Incident Overview
A Piper PA-46-310P experienced a loss of engine power and was forced to land in a residential area. Examination of the aircraft's fuel system revealed about one pint of fuel in each wing tank. No evidence of fuel spillage or aircraft fuel leaks was found at the accident scene, and there was no indication of an inflight fuel leak on the fuselage.
Fuel Consumption Discrepancy
The pilot reported that planned fuel consumption should have averaged 17 gallons per hour (GPH). However, the actual average fuel consumption for the trip was 19.9 GPH. The Piper PA-46-310P Pilot Operating Handbook (POH) predicts a fuel consumption of 17.5 GPH for the trip flight conditions.
Weight Calculation
The pilot calculated the maximum gross weight (GWT) of the aircraft at the start of the accident flight to be 4,116.7 pounds, which is 1.3 pounds below the maximum ramp weight of 4,118 pounds. However, a recalculation based on actual passenger and baggage weights determined that the aircraft was 260 pounds over maximum GWT before takeoff. The POH does not list any performance data for an aircraft operated over maximum GWT.
Conclusion
No probable cause was stated in the investigation source.
