Accident Sequence
After takeoff from runway 25 at Zell am See Airport, the aircraft began to roll left and right. It then banked right to an angle of 40 degrees, stalled, and crashed in an open field near the airport.
Occupant Status
All 21 occupants were rescued from the accident. Among them, eight sustained injuries.
Aircraft Damage
The aircraft was damaged beyond repair. Upon impact, the undercarriage and both wings were torn off.
Probable Cause
The official investigation found that the takeoff was initiated at an insufficient speed of 65 knots. It was determined that the friction locks of the throttles were not, or not properly, set prior to takeoff. Due to the vibration of the airplane, the throttles slowly retarded during the takeoff roll.
