During the winch launch at Innsbruck Airport (LOWI), the tow rope released at a height of approx. 10 metres above the ground during the initial climb. The aircraft then touched down hard. The pilot was seriously injured. The aircraft was severely damaged.

Probable causes
- Release of the towrope at low altitude over ground as a result of the reduction in towrope speed immediately after the aircraft has taken off.
- Delayed reaction of the pilot.
Probable factors
- No recent, practical experience of the pilot in winch launch interruptions.
- Almost no experience of the winch operator to be instructed with the design of the aircraft involved in the accident on the launch winch in question.
- Inadequate preparation of the winch operator.
- Light tailwind during the launch process.
- The launch winch operator was unable to interpret the wind situation accurately enough.
- Lower power output of the winch due to the still relatively cold motor.
