Narrative:

Approximately 150 yards after landing; the aircraft began to swerve left; then right. I applied full left rudder and could not regain control to get the aircraft back on the runway. Aircraft came to rest in a ditch 50 ft off the right edge of the runway in the direction of travel. Damage to the aircraft included collapsed right main gear; damage to the right wingtip; bent propeller and lower right longeron on fuselage. I was landing with nil indicated wind. Temperature was approximately 80-85 degrees. 2 on board. No obvious injuries. Pilot reaction or overreaction on rudder pedals was the likely cause.
