Narrative:

I was giving a biannual in a super viking. I told the gentleman to make a short field approach to landing. Turning base to final, I realized he was going to overshoot the second centerline past the 1000 ft marker. I immediately told him, 'you're going to overshoot, so don't try to force it, just land past it and do your normal short field procedures.' once we touched down, we were a little left of centerline, but slowly making our way to the edge of the runway. Halfway between the runway edge and the centerline, I was about to tell him to go around when he proclaimed he had lost his left brake, then the aircraft completely turned 80 degrees to the left, running off the runway. No one was hurt, no damage to aircraft, except for a small puncture, the size of a half of a penny on the underside flap fabric. The problem was caused by a blown tire, because the student pressed the brakes too hard on landing.

Title: THE TRAINING CREW DURING A FULL STOP LNDG, SHORT FIELD APCH, IN A SUPER VIKING, BLOWS A TIRE AND SKIDS TO A HALT SIDEWAYS ON THE RWY AT TA50, TX.

Narrative: I WAS GIVING A BIANNUAL IN A SUPER VIKING. I TOLD THE GENTLEMAN TO MAKE A SHORT FIELD APCH TO LNDG. TURNING BASE TO FINAL, I REALIZED HE WAS GOING TO OVERSHOOT THE SECOND CTRLINE PAST THE 1000 FT MARKER. I IMMEDIATELY TOLD HIM, 'YOU'RE GOING TO OVERSHOOT, SO DON'T TRY TO FORCE IT, JUST LAND PAST IT AND DO YOUR NORMAL SHORT FIELD PROCS.' ONCE WE TOUCHED DOWN, WE WERE A LITTLE L OF CTRLINE, BUT SLOWLY MAKING OUR WAY TO THE EDGE OF THE RWY. HALFWAY BTWN THE RWY EDGE AND THE CTRLINE, I WAS ABOUT TO TELL HIM TO GO AROUND WHEN HE PROCLAIMED HE HAD LOST HIS L BRAKE, THEN THE ACFT COMPLETELY TURNED 80 DEGS TO THE L, RUNNING OFF THE RWY. NO ONE WAS HURT, NO DAMAGE TO ACFT, EXCEPT FOR A SMALL PUNCTURE, THE SIZE OF A HALF OF A PENNY ON THE UNDERSIDE FLAP FABRIC. THE PROB WAS CAUSED BY A BLOWN TIRE, BECAUSE THE STUDENT PRESSED THE BRAKES TOO HARD ON LNDG.
