Probable cause

The pilot's misjudgment of distance and altitude which resulted in the collision with trees short of the runway.

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

According to the pilot, while on final to runway 27, he allowed the glider to develop a high sink rate, and he was unable to arrest the sink rate before the glider collided with the tree line. No mechanical problems were reported with the glider.
