Aircraft Accident/Incident Report

Sparks, Nevada 89510
Thursday, June 7, 2012 14:46 PDT

NTSB Narrative Summary Released at Completion of Accident

Both pilots reported that they were aware that other gliders were operating in the same area and that they were maneuvering over hilly terrain looking for convective lift when the collision occurred. The pilot of the Schempp-Hirth reported that he did not see the Centrair approaching head-on until it passed directly overhead. The pilot of the Centrair reported that he was in wings-level flight, descending through 7,000 feet above mean sea level, when he suddenly saw the Schempp-Hirth appear beneath the nose of his glider, slightly to his right, heading in the opposite direction. Neither pilot had time to react, and the left wingtip of the Schempp-Hirth collided with the right wingtip of the Centrair. Both pilots were able to return to the launch gliderport and land safely.

NTSB Probable Cause Narrative

The failure of both pilots to see and avoid each other, which resulted in a midair collision.
