A pilot flew for approximately 30 minutes earlier in the day but failed to refuel because the hose could not reach the aircraft. He did not visually verify fuel levels before departure and relied solely on gauges, leading to engine failure after three passes.

What happened

The pilot reported that he had operated an aircraft earlier on the same day for approximately 30 minutes. Although he intended to refuel prior to his subsequent flight, the fuel hose available at the location was too short to reach the aircraft's tank, so no fuel was added. Before departing, the pilot did not perform a visual inspection of the fuel quantity and instead relied entirely on the fuel gauges for assessment.

After takeoff, the pilot executed three passes, each measuring approximately 1/2 mile in length. During this phase of flight, the engine quit unexpectedly. A post-crash examination of the aircraft revealed no evidence of fuel remaining in the system.

Probable cause

The pilot's failure to ensure adequate fuel supply by relying on fuel gauges without a visual check and failing to refuel due to equipment limitations, resulting in fuel exhaustion.
