Narrative:

Upon landing, aircraft veered left and student corrected with right rudder. Going straight ahead, the aircraft veered slightly to the left and the aircraft made a large veer to the right. We hit a snowbank and the aircraft flipped upside down. The aircraft had no brakes on the instructor's side of the aircraft. I could not apply brakes, only rudder to try to stop the aircraft from swerving. I was unsuccessful in stopping the turning aircraft. I shut off the magnetos before we hit the snowbank. The 1946 aircraft should be retrofitted with brakes on both sides of aircraft. The design of the heel type brakes is a poor design. They can be applied inadvertently if the pilot uses the rudder which would multiply the problem.

Title: LOSS OF ACFT CTL ON LNDG PROC ROLLOUT. ACFT DAMAGED DURING NOSE OVER.

Narrative: UPON LNDG, ACFT VEERED L AND STUDENT CORRECTED WITH R RUDDER. GOING STRAIGHT AHEAD, THE ACFT VEERED SLIGHTLY TO THE L AND THE ACFT MADE A LARGE VEER TO THE R. WE HIT A SNOWBANK AND THE ACFT FLIPPED UPSIDE DOWN. THE ACFT HAD NO BRAKES ON THE INSTRUCTOR'S SIDE OF THE ACFT. I COULD NOT APPLY BRAKES, ONLY RUDDER TO TRY TO STOP THE ACFT FROM SWERVING. I WAS UNSUCCESSFUL IN STOPPING THE TURNING ACFT. I SHUT OFF THE MAGNETOS BEFORE WE HIT THE SNOWBANK. THE 1946 ACFT SHOULD BE RETROFITTED WITH BRAKES ON BOTH SIDES OF ACFT. THE DESIGN OF THE HEEL TYPE BRAKES IS A POOR DESIGN. THEY CAN BE APPLIED INADVERTENTLY IF THE PLT USES THE RUDDER WHICH WOULD MULTIPLY THE PROB.
