Collision with terrain involving a PZL - Bielsko SZD-42-2 Jantar 2B, VH-IUG, 10km NE Narrogin, (ALA), WA on 7 December 1996

The pilot reported that it was the first time he had flown the type of glider and it had been over 3 years since he had flown a glider with water ballast. Prior to the flight he had forgotten to drain the water and he had departed with the ballast tank about half full. As he made his approach to land, during an out-landing, the water shifted causing one wind to drop suddenly. The wing tip hit the top of a fence, yawing the aircraft to the right. The landing gear was torn off on touchdown and the left wing tip then dug in causing the aircraft to ground loop to the left.
