Incident Details
The airplane experienced a ground loop while conducting routine pattern work. The pilot had completed one successful touch-and-go landing.
Sequence of Events
Approximately 300 feet from touchdown, the pilot noticed a quartering left tailwind. He considered performing a wheel landing with partial flaps but decided instead to execute a full stall landing with full flaps. The touchdown was smooth, but during the landing roll, the airplane began to veer to the right. The pilot applied left rudder but received no response. He then applied additional left rudder and some left brake. In response, the airplane immediately veered left at a 45-degree angle to the runway centerline. The pilot reacted with right rudder and brake, causing the airplane to turn right until it was pointed 30 degrees to the right of the centerline. As the airplane reached the centerline, it ground looped.
Damage
The left axle broke, and the left spar sustained substantial damage.
