Narrative:

Front seat pilot (fsp) (trainee) was experienced CFI, but not yet conventional gear qualified. This was his second conventional gear (tailwheel) training flight in the citabria. I was in the rear seat administering the training. Fsp (front seat pilot) made a 3 point landing and was rolling out, slowing down to exit runway on taxiway to the right. For whatever reason, the aircraft veered sharply to the left and fsp (front seat pilot) initiated a go around and we departed the runway at a 45 degree angle and became airborne. Unfortunately, we did knock off a taxiway light and tore fabric in bottom of the airplane. We flew a conventional l-hand pattern and landed the airplane without incident. The rear seat pilot does have flight controls: stick and rudder. I keep my feet lightly on the rudder so as to sense any rudder input from the fsp (front seat pilot). However, he might have applied brakes to slow down for the turn off the runway (right) onto the taxiway and applied too much left brake. I can think of no other apparent reason for the sharp left turn. The tower reported the winds ese at 4 KTS.

Title: CH7A PLT AND CFI EXPERIENCE LOSS OF CTL ON LNDG ROLLOUT AND CAUSE DAMAGE TO A TXWY LIGHT AND BOTTOM OF ACFT AT OJC, KS.

Narrative: FRONT SEAT PLT (FSP) (TRAINEE) WAS EXPERIENCED CFI, BUT NOT YET CONVENTIONAL GEAR QUALIFIED. THIS WAS HIS SECOND CONVENTIONAL GEAR (TAILWHEEL) TRAINING FLT IN THE CITABRIA. I WAS IN THE REAR SEAT ADMINISTERING THE TRAINING. FSP (FRONT SEAT PLT) MADE A 3 POINT LNDG AND WAS ROLLING OUT, SLOWING DOWN TO EXIT RWY ON TXWY TO THE R. FOR WHATEVER REASON, THE ACFT VEERED SHARPLY TO THE L AND FSP (FRONT SEAT PLT) INITIATED A GAR AND WE DEPARTED THE RWY AT A 45 DEG ANGLE AND BECAME AIRBORNE. UNFORTUNATELY, WE DID KNOCK OFF A TXWY LIGHT AND TORE FABRIC IN BOTTOM OF THE AIRPLANE. WE FLEW A CONVENTIONAL L-HAND PATTERN AND LANDED THE AIRPLANE WITHOUT INCIDENT. THE REAR SEAT PLT DOES HAVE FLT CTLS: STICK AND RUDDER. I KEEP MY FEET LIGHTLY ON THE RUDDER SO AS TO SENSE ANY RUDDER INPUT FROM THE FSP (FRONT SEAT PLT). HOWEVER, HE MIGHT HAVE APPLIED BRAKES TO SLOW DOWN FOR THE TURN OFF THE RWY (R) ONTO THE TXWY AND APPLIED TOO MUCH L BRAKE. I CAN THINK OF NO OTHER APPARENT REASON FOR THE SHARP L TURN. THE TWR RPTED THE WINDS ESE AT 4 KTS.
