Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The glider pilot reported he was returning to land when he noticed another glider waiting for departure on the runway. He elected to land instead on another runway that required that he fly further. The pilot said that he turned on the base leg of the traffic pattern too far away from the intended runway and that he did not anticipate the substantial downdraft and very strong headwind that he encountered on final approach. The glider landed approximately 500 feet short of the intended runway and impacted terrain and a railroad embankment, causing substantial damage to the glider's fuselage and right wing.
