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 student pilot reported that, during the flare for landing, the airplane experienced ground effect and was settling down to the runway when it was hit by “a very intense wind shear with a gust…” The pilot stated that the airplane yawed to the left and that he could not recover as the airplane exited the runway onto the grass. The airplane’s right wing was substantially damaged when it collided with a Precision Approach Path Indicator (PAPI). The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
