DG-1000T stalls in shallow skidding turn to final at low airspeed

The pilot of a DG-1000T and a glider-student passenger were seriously injured when the glider stalled in a shallow, skidding turn to final at low airspeed; destroyed. After a winch launch to 440 m at Boberg in 8–10 kt NW wind, the pilot circled in the SW pattern area, using the auxiliary engine twice. By 11 min, height was down to 200 m ~1 km SW; two further circles left it at ~125 m, forcing a short circuit. From ~100 m AGL the pilot turned left for final at low airspeed; witnesses reported a shallow, skidding turn; the glider stalled, dropped out and hit a fallow field ~150 m east of the field at high nose-down pitch. No technical faults.

1. Winch launch + local pattern circles: Winch launch to 440 m at Boberg with two on board; the pilot circled in the southwest pattern area as height steadily decreased, using the auxiliary engine twice to extend the flight.
2. Height drop to 200 m at 1 km SW: After about 11 min the glider was at 200 m AGL about 1 km southwest of the launch point.
3. Two more circles → ~125 m: Two further circles brought height down to ~125 m, requiring a shortened landing pattern; the student-passenger noted she had never been so low at that position before.
4. Low airspeed in turn to final: From about 100 m AGL the pilot turned left for final at noticeably low airspeed.
5. Shallow, skidding stall in turn: Witnesses observed a shallow, skidding (schiebend) turn at very slow speed; the glider exceeded the critical angle of attack and dropped out of the turn.
6. High-pitch impact 150 m east of field: The glider impacted a fallow field about 150 m east of the airfield with a steep nose-down attitude; both occupants seriously injured, airframe destroyed. No technical faults.
