Analysis

The glider pilot entered a thermal with three other sailplanes and began to climb. Two of the sailplanes were about 1000 ft below him and the other plane was about 500 ft above. As the pilot was climbing to about 4000 ft MSL, he lost sight to the sailplane above him and elected to leave the thermal. As he was preparing to leave, he saw the other plane on a collision course. He took evasive action, but was too late. The right wing of his plane struck the left wing of N6KS. About 10 ft of the right wing separated and the plane went out of control. The pilot bailed out successfully and the glider came to rest upright in an open field. The pilot of the other glider managed to bail out, but his parachute did not open.

After releasing from the tow aircraft, the glider pilot proceeded to gain altitude in a thermal along with other sailplanes. At an altitude of about 4000 ft MSL, a collision occurred with one of the other sailplanes. About 9 ft of the left wing separated and the plane went out of control. The pilot failed to release the canopy, but was able to free himself from the plane. Reportedly, he had sufficient time and altitude to open his parachute, but the chute did not open. An examination of the parachute revealed that the rip chord was extended with pins free of the back pack retainers. The pilot chute was deployed along with a small portion of the main chute. The pilot of the other glider bailed out successfully.
