Probable cause

The pilot's loss of control in flight as the result of a strong downdraft and wind shift.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The glider pilot was competing in a soaring competition and was descending along a ridge during a cross-country flight. He 'encountered a strong downdraft and wind shift to the tail component which caused a loss of airspeed and altitude and a subsequent descent into the trees.'
