Probable cause

The pilot's inattentiveness during the aircraft preflight and his failure to maintain clearance above the trees.

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 pilot reported that he normally sets the altimeter to zero prior to takeoff. The pilot reported that he was distracted during the preflight and he forgot to reset the altimeter which was set to field elevation, approximately 1,000 feet. This resulted in the pilot releasing from the tow 1,000 feet lower than what he thought he was. The pilot stated the glider hit the tops of trees while on final approach.
