Event Location
Probable Cause
The pilot's failure to maintain directional control during the landing roll in gusty crosswind conditions, which resulted in a runway excursion and a collision with a concrete barrier wall.
Full Narrative
The pilot of a tailwheel-equipped airplane reported that during the landing roll, a "strong gust" of wind lifted the left wing and the airplane veered off the runway to the right. During the runway excursion, the airplane impacted a concrete barrier wall in the ramp area. The firewall sustained substantial damage.
The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation.
The nearest automated weather observing station 15 nautical miles away from accident airport, about the time of the accident, reported the wind at 210 degrees true at 4 knots. The airplane landed on a 270 degrees magnetic heading.
