Incident Overview
The pilot of a single-engine aircraft reported refueling at Mobile but did not visually inspect the fuel tanks. At the time of the engine power loss, the pilot believed approximately 15 gallons of fuel remained.
Actions Taken
After the engine lost power, the pilot switched the fuel tank selector from left to right and engaged the auxiliary boost pump on the "HI" setting for a few moments. The engine did not restart. The aircraft subsequently settled into trees and came to rest on the ground below.
Emergency Checklist Procedure
The emergency checklist for engine failures in this aircraft specifies that the auxiliary fuel pump should be placed in the "ON" position for 3 to 5 seconds and then turned "OFF." The "HI" position is intended for use only in the event of an engine-driven fuel pump failure during takeoff or high power operations.
Summary
The pilot's failure to visually verify fuel quantity after refueling, combined with incorrect use of the auxiliary boost pump setting during an engine failure, preceded the forced landing into trees. No further details on the aircraft or injuries were provided.
