Aircraft lost power during initial climb after a normal runup. The pilot attempted to maintain RPM by pumping the throttle but could not sustain altitude, resulting in a ditching approximately half a mile from the runway.

What happened

The pilot completed a normal engine runup before initiating takeoff. During the initial climb phase, the aircraft began losing power. The pilot attempted to compensate for the loss by pumping the throttle to maintain power output; however, it was not possible to sustain the required climb RPM. Consequently, the aircraft was ditched in approximately 8 feet of water, located roughly half a mile from the runway.

The investigation

An examination of the wreckage disclosed that the fuel strainer gasket was defective. This defect caused the engine to run lean, leading to the loss of power during the critical climb phase.

Probable cause

A defective fuel strainer gasket that caused the engine to run lean, resulting in a loss of power during initial climb.
