DG-202 wheel brake fails on landing rollout; collision with hangar

After cutting short a local familiarization flight from Münster/VS (LSPU) due to deteriorating weather, the pilot landed a DG-202 on rwy 23 at ~100 km/h. The glider touched down past the midpoint, leaving ~350 m for rollout. Near the end the pilot turned right off centerline onto the grass strip and tried to brake — the drum brake produced no effect despite full handle travel. The glider rolled across the grass, crossed a public road, and struck a hangar corner, a sign, and two barrier posts. The drum brake's Bowden cable was loose (sole cause). Substantial damage to leading edges, left wing root, and nose. Pilot uninjured.

1. Local landing after early return: After a local familiarization flight from Münster/VS (LSPU) in the Obergoms region, the pilot returned early due to worsening weather and landed on downhill runway 23.
2. Loose brake Bowden cable: The Bowden cable for the drum wheel brake was loose and not correctly tensioned, so the brake could not be operated; brake tension is checkable pre-flight under the wheel cover.
3. Late touchdown: Final approach was flown at 100 km/h, 10 km/h over best-glide approach speed, for expected headwind. Touchdown came past midpoint, leaving ~350 m for rollout.
4. Brake fails on rollout: Near the runway end, the pilot turned right onto the grass strip toward the apron and tried to brake; the drum brake produced no effect despite full handle travel.
5. Crosses road, hits objects: Without effective braking, the glider rolled across the grass strip, crossed a public side road, and struck the corner of a hangar, a signal board, and two barrier posts before stopping.
6. Collision damage; no injury: Pilot uninjured. Severe damage to both wing leading edges, left wing root, and fuselage tip. Investigation closed by summary report under VSZV Art. 46; no systemic factor.
