Incident Summary
A pilot reported that during a flight, the engine lost power while descending through 2,300 feet approximately 7 miles from the destination airport. The pilot executed a forced landing on a highway. During the landing rollout, the aircraft's right wing struck a guard rail post, resulting in the wing separating from the aircraft.
Pre-Flight Inspection
According to the pilot, the pre-flight inspection included checking the fuel tanks by dipping fingers into the tanks to estimate the remaining fuel quantity. Neither tank was full, but the pilot estimated that sufficient fuel remained for the planned flight. The aircraft's fuel gauges had a label taped to the instrument panel indicating that they were unreliable.
Power Loss and Pilot Statement
When the power loss occurred, the pilot remarked to the rated passenger, "We're out of gas." This statement was reported by the passenger.

Investigation Findings
The investigation did not specify a probable cause. The pilot's method of fuel estimation and the known unreliability of the fuel gauges are noted in the report.
