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 he was flying an approach in a 90-degree, 20 knot crosswind, when during the landing on the grass runway, the wind pushed the airplane sideways and it subsequently impacted the terrain. The airplane sustained substantial damage to the lower fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the wind was 080o at 8 knots with gusts to 17 knots. The pilot reported he was attempting to make a short field landing and was “flying below stall speed”.
