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 of the tailwheel equipped airplane reported that during the landing roll in cross wind conditions, he was unable to maintain control of the airplane. The pilot further reported that the airplane veered to the left and exited the runway. The airplane sustained substantial damage to the right aileron and right elevator. The pilot reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The pilot landed runway 17, and reported the wind as 110 degrees true, 10 nautical miles per hour (knots), with gusts 15-20 knots. A review of local weather from an automated weather observation station located on the airfield, showed that at the time of the accident the wind was reported as 080 degrees true at 6 knots.
