A helicopter experienced an engine power loss during autorotation after low fuel warnings. The pilot had proceeded without refueling despite a low fuel indication, leading to a forced landing on a hillside.

Incident Overview

A helicopter pilot reported that the fuel gauge indicated 150 pounds of fuel remaining at the start of a flight to a drop point. Believing the drop point to be within 2 to 3 minutes of the departure point, the pilot chose to proceed without refueling. While hovering and being guided into the drop point, the low fuel warning light flickered. The pilot completed the drop, and during the return to the refueling area, the warning light flickered three more times.

Fuel Indications and Power Loss

Upon arrival at the refueling area, the pilot noted that the fuel gauge showed approximately 50 to 60 pounds of fuel remaining. Shortly thereafter, while the helicopter was still about 50 to 60 feet above ground level (AGL), the engine lost power. The pilot initiated an autorotation and landed the helicopter on a hillside in a logging area, maneuvering to avoid a truck.

Outcome

The helicopter came to a stop on the hillside without further incident. No injuries were reported, and the aircraft sustained damage consistent with a forced landing.
