N48029 – LET Blanik L-13 – 2008-07-21 NTSB Accident Report

On July 21, 2008, a Let Blanik L-13 (N48029) was involved in an accident near Arlington, WA. The accident resulted in 1 minor injury. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this accident to be: The pilot's failure to maintain clearance from a tree while making an off-field landing in a glider. Contributing to the accident was the pilot's inadequate compensation for the gusting winds.

After a fifteen minute glider flight, the pilot entered the traffic pattern for a planned full-stop landing on a grass airstrip that ran adjacent to the active paved runway. He then extended his downwind leg in order to create a greater clearance between himself and a powered airplane that was landing on the paved runway. After rolling out on base leg, the pilot realized that he had extended his downwind leg too far to reach the grass strip under the current gusting wind conditions. He therefore decided to land in a field short of the grass runway. While maneuvering to land in that field, he failed to maintain clearance from a nearby tree. After the wing of the glider hit the tree, it cart wheeled into the field, and sustained wrinkling and crushing damage to both its wings and fuselage.

This accident is documented in NTSB report SEA08CA163. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N48029.
