During climb-out from a lake, an airplane experienced total engine power loss. The pilot made an emergency landing on another lake. Investigation found rubber-like material in the fuel header tank blocking the fuel port.

Incident Overview

While climbing out from a lake, approximately 300 to 400 feet above terrain covered with tall trees, the airplane's engine lost all power. The pilot maneuvered the aircraft to a nearby lake and executed an emergency landing.

Investigation Findings

Post-accident examination of the engine and fuel system revealed the presence of a piece of rubber-like material inside the fuel header tank. The origin of this material could not be determined during the investigation.

During the inspection process, the material was manipulated within the fuel header tank. It was found that the material could be positioned to cover the fuel port that leads to the fuel pump. When the material covered this port, it blocked the flow of fuel to the fuel pump, thereby causing the engine power loss.
