Incident Overview
A single-engine aircraft operating a ferry flight from Budapest-Ferihegy to Warsaw crashed on the slope of a hill near Pilisszentlélek. Both occupants sustained fatal injuries.
Flight Details
The flight departed Budapest-Ferihegy as a ferry movement destined for Warsaw. En route, the crew encountered icing conditions and poor weather. Air traffic control cleared the aircraft to return to Budapest and instructed the pilot to maintain a minimum altitude of 4,000 feet.
Accident Sequence
Shortly after receiving the return clearance, the aircraft lost altitude and impacted the terrain on a hillside near Pilisszentlélek. The impact and subsequent damage were catastrophic, resulting in fatalities for both individuals on board.
Investigation Findings
Official investigation determined that the accident was caused by a loss of control. The loss of control occurred following an excessive accumulation of ice on the fuselage, wings, and tail surfaces. The icing conditions encountered during the flight led to ice buildup that degraded the aerodynamic performance of the aircraft.
Probable Cause
The probable cause of the accident is that the crew lost control of the airplane following an excessive accumulation of ice on fuselage, wings and tail.
