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 landing with a right crosswind, the airplane drifted left of runway centerline. The pilot applied right bank and left rudder control input, but the airplane continued to drift left. The pilot then increased engine power for a go-around, but the left wing dropped, and the left bank increased. The pilot continued to attempt recovery, but the airplane was too low. The airplane subsequently collided with the terrain next to the runway. The left wing and rudder sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
