Analysis

The flight instructor of the tailwheel-equipped airplane reported that the airplane swerved slightly to the left during landing roll on an instructional flight with a pilot receiving instruction at the controls. After the tailwheel touched the ground, the pilot receiving instruction attempted to control the left swerve with the right rudder. This resulted in the airplane veering to the right side of the runway and colliding with a snowbank. The airplane subsequently nosed over substantially damaging the fuselage, right wing strut and vertical stabilizer. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
