Circumstances:
The pilot had received winch launch training eighteen months earlier but had not carried out any further launches until the day of the accident. His flying experience on the Libelle was restricted to two flights, some four months earlier. On the day of the accident, he underwent three winch launch check flights with a club instructor in a K7 glider, resulting in a satisfactory standard being assessed. It was reported that the pilot then prepared for a winch launch in the Libelle, which included selecting full nose down elevator trim to counter an expected nose up pitch tendency during launch. Shortly after the glider became airborne, the nose pitched up very steeply, the right wing dropped and struck the ground, resulting in the glider cartwheeling into a fence.
