NTSB summary
HISTORY OF FLIGHT On August 18, 2011, about 1640 mountain daylight time, a Briegleb BG-12B, N559Y, collided with terrain during approach to King Mountain Glider Park Airport, Moore, Idaho. The pilot was operating the experimental amateur-built glider under the provisions of Title 14 Code of Federal Regulations Part 91. The commercial pilot sustained fatal injuries; the glider was substantially damaged during the accident sequence. The local flight departed King Mountain at 1436. Visual meteorological conditions prevailed, and no flight plan had been filed. At the time of the accident, an annual Fly-In was underway at the airport. The pilot had arrived earlier in the week, and airfield records indicated that he flew the glider two times during the period prior to the accident. A witness, who was located midfield under an awning on the east verge of the runway was seated and facing northwest, when he heard the pilot report on the common traffic advisory frequency that he was inbound for landing. A few minutes later, his attention was drawn to a glider flying past the awning in level flight, heading north along runway 34 at an altitude of about 75 feet above ground level (agl). He did not see the glider prior to that moment, and while he could not accurately judge its airspeed, he surmised that it was traveling at a speed higher than appropriate for the glider type. He was startled, and expressed considerable alarm at the glider's position relative to the airfield. The glider continued to the end of the runway, and then began a smooth pitch-up maneuver. During the initial clim
Probable cause
The pilot’s decision to perform a low pass over the runway in the opposite direction of his intended landing, and his subsequent failure to maintain airspeed and glider control during the reverse-course maneuver. Contributing to the accident was the effect of the pilot's failure to take his prescribed medications.
