Probable cause

The pilot’s failure to maintain an adequate approach in gusting tailwind conditions, which resulted in a runway overshoot.

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 reported that, during approach to a backcountry, private dirt airstrip, the wind was swirling, and he decided to go around. During the second landing attempt, the airplane descended below the treetops surrounding the airstrip, which prevented the pilot's ability to safely perform a go around, and a wind gust from behind the airplane pushed it past the end of the runway into trees. The airplane sustained substantial damage to both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was variable at 15 knots, gusting to 15 to 20 knots.
