Event Summary
An incident occurred during the landing roll when the tailwheel of an airplane began to shimmy. The left tailwheel spring subsequently became disconnected. The aircraft spun approximately 270 degrees, and the left wing contacted the runway surface. The airplane then departed the right side of the runway before coming to rest.
Sequence of Events
According to the pilot, the tailwheel shimmy initiated the chain of events. The left side tailwheel spring disconnected during the landing roll. The airplane then rotated around 270 degrees, causing the left wing to make contact with the runway. The airplane traveled off the right side of the runway and came to a stop.
Pilot Report
The pilot stated that the groundspeed was very slow at the time of the spring disconnection. This condition resulted in a lack of rudder authority, which prevented the pilot from maintaining directional control of the airplane.
