A pilot experienced power loss from fuel starvation while en route. Insufficient altitude prevented engine restart or wind-aligned landing. The landing gear collapsed during a crosswind landing.

Incident Summary

The pilot experienced a power loss due to fuel starvation while en route. The altitude was insufficient to allow the pilot to restart the engine or select a landing area into the wind. The landing gear collapsed during the subsequent landing, which occurred in a strong crosswind.

Post-Accident Examination

A post-accident examination by the Federal Aviation Administration (FAA) revealed that the fuselage tank was empty, while usable fuel remained in both wing tanks. The spark plugs showed evidence of exposure to heat and a lean mixture. Additionally, the fuel selector valve was found to have an external leak.

Pilot Statement

The pilot did not recall which fuel tank was selected when the power loss occurred.

FAA Assessment

The FAA stated that, based on the leaky valve, the capacity of the fuselage tank, and the length of the flight, it was possible the pilot was selected to the fuselage tank and experienced fuel starvation.
