Accident Sequence
Shortly after takeoff from Mindelheim-Mattsies Airport, while in initial climb, the pilot informed air traffic control about problems and elected to return. While completing a sharp turn to the right at a relatively low altitude, the aircraft stalled and crashed in a field located less than 2 km from the airfield. The aircraft was destroyed and the pilot, sole on board, was killed.
Probable Cause
The official investigation determined that the fuel filler cap on the right fuel tank was missing and fuel was leaking, necessitating an emergency return. While completing a last turn to the right, the aircraft stalled because its speed was insufficient and the distance from the ground was too low to expect recovery.
Aircraft and Operator
The aircraft was operated by Burkhart Grob Luft-und-Raumfahrt, later renamed Grob Aerospace.
