Incident Overview
A commercial pilot reported that during preflight preparations, he initially requested 100 pounds of fuel be added to both fuel tanks. Later, he decided more fuel was needed and requested the tanks be topped off. However, he did not verify the fuel levels or check the fuel gauges before takeoff.
In-Flight Fuel Situation
Approximately one hour after departure, the pilot checked the fuel gauges for the first time. They indicated about 900–1,000 pounds of fuel per side, leading him to realize the tanks had not been topped off as requested. He reduced engine power to conserve fuel and extend flight endurance while continuing toward his destination.
Low Fuel Warning and Diversion
When the gauges showed roughly 400–500 pounds per side, the low fuel lights for both wing tanks illuminated. The pilot informed air traffic control of the low fuel situation and diverted to the nearest airport.
Approach and Landing
The pilot reported that the airplane was high and fast on the visual approach. He misjudged the height above the ground and later stated the airplane "landed very hard." The left main landing gear and nose gear collapsed, causing the airplane to veer off the runway. The left wing sustained substantial damage.
Mechanical Status
The pilot reported no preaccident mechanical malfunctions or failures that would have precluded normal operation.
Probable Cause
The official finding stated the probable cause was the pilot's failure to fly a stabilized approach and his inadequate landing flare, resulting in a hard landing. Contributing to the accident was the pilot's failure to ensure the airplane was properly serviced with fuel before departure.
