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 was cleared to land on runway 26. The recorded surface wind at the airport around the time of the accident was from 330 to 340 degrees at 14 to 18 knots, gusting to 25 knots; a peak wind gust from 350 degrees at 26 knots was recorded about 7 minutes after the accident. The pilot said that he landed on the left main gear with the right main intermittently touching the ground and tried to lower the right wing to improve wheel-to-runway contact but was unsuccessful because of a wind gust. The airplane swerved off the left side of the runway onto the soft grass area, where the airplane’s main landing gear collapsed, and both wings were substantially damaged. The pilot reported no preaccident mechanical malfunctions or failures that would have precluded normal operations.

Factual narrative

The pilot stated he was cleared to land on runway 26. He estimated the winds were “varying from the west to the north at 10 to 14 knots”. The surface winds at the airport were 330 degrees at 18 knots gusting to 23 knots near the time of the accident. He landed on the left main gear with the right main intermittently touching the ground. He attempted to lower the right wing to improve wheel to runway contact. Due to a wind gust, he was unsuccessful. He felt the left main gear became “mushy” and he was braking to avoid an overrun, when the airplane swerved off the left of the runway onto the soft grass area. The airplane’s main landing gear collapsed and both wing’s outer structure incurred substantial damage before coming to a complete stop. The pilot reported no pre-accident mechanical malfunctions or failures that would have precluded normal operations.
