Aircraft Accident/Incident Report

Hailey, Idaho 83313
Saturday, July 23, 2011 8:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that shortly after takeoff, he retracted the landing gear, and the engine lost power. The pilot lowered the landing gear and landed on the remaining runway. During the landing roll, the airplane collided with a taxiway sign. The Garmin G1000 integrated flight instrument system data was extracted for analysis. The unit recorded flight and engine data for the time between engine start and the accident. The data revealed that during takeoff and initial climb the engine’s fuel flow supply increased from about 35 gallons per hour (gph) to about 45 gph. Shortly thereafter, the engine's exhaust gas temperatures (egt) and rotations per minute (rpm) decreased to sub idle parameters. The airplane is equipped with a dual-speed, dual-pressure, electric vane-type auxiliary fuel pump. The pump is controlled by a single, three-position switch located on the pilot’s subpanel to the left of the landing gear handle. The flight manual for the airplane includes a statement that reads “use of the auxiliary fuel pump in the HI position may cause an excessively rich mixture and severely reduce available engine power or even cause the engine to cease combustion completely. The HI position should not be used for takeoff unless there is a failure of the engine driven fuel pump.” The pilot reported that during the takeoff roll he may have inadvertently switched the auxiliary fuel pump to the HI position. Because the auxiliary fuel pump toggle switch is located adjacent to the landing gear handle, it is likely that the pilot mistakenly toggled the fuel switch instead of the landing gear handle. Postaccident examination revealed no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's inadvertent activation of the auxiliary fuel pump, which resulted in a loss of engine power during takeoff.
