What happened
On May 2, 2005, a Cessna 177-RG, registration EC-GAX, departed from the Casarrubios del Monte airfield in Toledo for a planned local flight. The aircraft was operated privately and carried a pilot and one passenger. Approximately 20 minutes into the flight, while cruising at an altitude of roughly 500 feet, the pilot experienced a loss of engine power accompanied by audible engine explosions.
In response to the power loss, the pilot performed an emergency landing in a recently plowed field near Alcaudete de la Jara. To prevent the aircraft from flipping, the pilot landed with the landing gear retracted. The aircraft traveled approximately 50 meters along the ground before coming to a complete stop. Both occupants were uninjured and were able to evacuate the aircraft safely. The aircraft sustained minor damage, specifically to one propeller blade and the lower fuselage.
The investigation
The investigation focused on the engine failure and the state of the aircraft's fuel system. Upon inspection of the aircraft at the site, investigators found that the fuel tanks were empty. There were no visible signs of leaks within the fuel system, nor were there any fuel spills found on the ground. Additionally, no fire occurred during the incident.
Findings
- The pilot had departed with an estimated 50 to 60 liters of fuel, which was believed to be sufficient for an additional 90 minutes of flight.
- The engine failure was characterized by a loss of power and engine explosions.
- Fuel exhaustion was the primary cause of the engine failure, as the tanks were found empty with no evidence of leaks or external fuel loss.
