Ka 6CR student spins while thermalling; only theoretical spin training

A student pilot was fatally injured when a Ka 6CR spun from a thermal turn at ~250 m AGL and was not recovered before vertical impact; destroyed. The student — 40 h total, 6 launches on the Ka 6CR — had aerotow-launched solo at Kempten-Durach in light VFR. After ~20 min thermalling near the field he undershot the minimum airspeed in a turn, stalled and spun. After one to two turns with no observable recovery action the glider hit a meadow ~1 km southeast almost vertically. Almost all his dual training had been on the ASK 21, which cannot spin without added CG weights; he had seen only pre-spin signs. No technical faults; mass/CG in limits.

1. Solo Ka 6CR aerotow + thermalling: Student launched at 12:49 from Kempten-Durach by aerotow in a Ka 6CR for a solo thermalling flight near the field; about 40 h total / 6 launches on type.
2. Spin training only on ASK 21: All dual training had been on the ASK 21 except the first two launches; it cannot spin without added CG weights, so the student had only seen pre-spin signs, never the spin or recovery.
3. Low altitude in pattern (~250 m AGL): After ~20 min the glider was observed thermalling near the airfield at ~250 m AGL — adequate for spin recovery only if entry was recognised early.
4. Airspeed undershot in turn: In a thermalling turn the student allowed the airspeed to fall below the minimum for the bank; the Ka 6CR exceeded the critical angle of attack.
5. One to two-turn spin, no recovery: The over-stalled glider departed into a spin; witnesses observed one to two turns with no observable recovery input.
6. Near-vertical impact 1 km SE of field: The Ka 6CR impacted a meadow about 1 km southeast of Kempten-Durach almost vertically; the student was fatally injured and the airframe destroyed, with no technical faults found.
