Probable cause

The pilot’s failure to attain a proper glidepath on approach for landing in gusting wind conditions, which resulted in an off-airport landing and impact with soccer goal posts.

Findings · 5

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 pilot of a glider reported that he encountered turbulence and heavy sink on the downwind leg of the traffic pattern. He added that, on final approach, the glider encountered additional "heavy sink" and a "gusting headwind." He further added that the glider was approaching soccer fields short of the runway and that he cleared an initial goal post but that the glider impacted another goal post and impacted the ground. The glider sustained substantial damage to the fuselage and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation. A review of recorded data from the automated weather observation station located about 12 miles east of the airport reported that, about 14 minutes after the accident, the wind was variable at 6 knots, gusting to 15 knots. The airplane was landing on runway 25.
