Probable cause

The failure of the lower right side longeron tail-spring support area during landing due to excessive corrosion.

NTSB narrative

The pilot reported he made 10 landings during light and variable wind conditions, the first nine of which were uneventful; however, on the 10th landing there was a sudden uncontrolled “jerk” to the left. The pilot was unable to maintain control and the airplane departed the runway into the grass. A postaccident examination of the airplane revealed the lower right longeron tail-spring failed due to corrosion.
