What happened
During a dual instruction flight, the aircraft experienced a complete loss of power due to fuel exhaustion before reaching the intended destination airport. The flight instructor noted that the fuel tanks were physically low, yet both fuel quantity indicator gauges displayed ample fuel for the planned duration of the flight, which included approximately one and a half hours of flight time plus a half-hour reserve.
The aircraft remained airborne for roughly one hour and twenty minutes before the engine lost power. Following the loss of propulsion, the pilot executed a forced landing on a road, resulting in damage to the airplane.
The investigation
Examination of the event focused on the discrepancy between the fuel quantity indicators and the actual fuel state. The flight instructor reported that while the tanks were low, the gauges indicated sufficient fuel for the remaining flight time with reserve.
