Accident Overview
A pilot experienced a ground loop while landing on runway 33. The incident occurred when a gust of wind affected directional control as the tail wheel was about to touch down.
Sequence of Events
The pilot reported that as the airplane reached approximately midfield on the landing roll, a gust of wind overcame the ability to keep the airplane centered on the runway. This wind gust caused the airplane to yaw to the right. The gust was encountered just as the tail wheel was about to touch down, a phase the pilot described as "when rudder is least effective."
Damage
The ensuing ground loop sheared the attach bolts on the left main landing gear, causing it to collapse. The right wing also sustained damage.
Reported Wind Conditions
The reported wind at the time was from 010 degrees at 5 knots.
Conclusion
The aircraft ground looped due to a wind gust during the landing roll, resulting in structural damage to the landing gear and wing.
