Accident Summary
A pilot encountered a loss of engine power shortly after takeoff at an estimated altitude of 300 feet above ground level. The pilot, who had just taken off, reported that the engine began to lose power. He then selected the right fuel tank, which resulted in a partial restoration of power. However, believing he was too low to execute a safe return, the pilot focused on executing a forced landing.
Preflight and Ground Operations
Before the flight, a new fuel valve had been installed. As part of the installation and testing, a mechanic added 10 gallons of fuel to each wing tank. Prior to departure, the pilot filled the right fuel tank but did not visually inspect the fuel quantity in the left tank. The pilot reported that the taxi and engine runup lasted approximately 15 minutes, and during this time the fuel selector was positioned on the left tank.
Post-Accident Examination
An examination following the incident revealed that the left fuel tank still contained 15 gallons of fuel. However, the left wing tip was resting on the ground, and it was noted that the fuel tanks interconnect through the fuel valve even when the valve is in the off position. The engine was examined and no mechanical failures were found.
Relevant Procedures
The aircraft owner's operating manual includes a pre-takeoff checklist that instructs the pilot to place the fuel selector on the tank containing the greatest amount of fuel. In this case, the pilot did not follow that instruction, as he had not verified the left tank quantity and had consumed fuel from it during ground operations.
