Narrative:

I was flying as a CFI with a student in her own aircraft. Type aircraft was a small aircraft single engine land aircraft (model yr) with conventional gear conversion, oversized tires, a STOL wing conversion. I demonstration'd a touch-and-go. The student had about 29 hours but was still having trouble with directional control on landing and proper touchdown (adjusting the nose). We flew a landing to full stop which was acceptable and taxied back and took off. The next approach the student touched down and bounced. On the next touchdown the aircraft swerved to the left. I took control of the aircraft and kept it from leaving the runway with the rudder and brakes. I also applied full nose up elevator to get the tail down. As I straightened the aircraft, the tail started to rise. I still had the brakes on. The aircraft continued up and over on its nose and stopped on its back. We were in harnesses and were unhurt. Shortly after the incident, the wind tee on the runway showed a tail wind. Things I could have done: (1) got off the brake (I have had good results prior using brake and back pressure in such situations but the owner had just reworked the brakes). (2) added power after I had regained control of the aircraft. The FAA classified the event as an incident.

Original NASA ASRS Text

Title: FLT INSTRUCTOR TOOK OVER FROM STUDENT IN A CONVENTIONAL GEAR SMA ACFT DURING LNDG AND WAS UNSUCCESSFUL IN KEEPING THE ACFT FROM NOSING OVER ON ITS BACK.

Narrative: I WAS FLYING AS A CFI WITH A STUDENT IN HER OWN ACFT. TYPE ACFT WAS A SMA SINGLE ENG LAND ACFT (MODEL YR) WITH CONVENTIONAL GEAR CONVERSION, OVERSIZED TIRES, A STOL WING CONVERSION. I DEMO'D A TOUCH-AND-GO. THE STUDENT HAD ABOUT 29 HRS BUT WAS STILL HAVING TROUBLE WITH DIRECTIONAL CTL ON LNDG AND PROPER TOUCHDOWN (ADJUSTING THE NOSE). WE FLEW A LNDG TO FULL STOP WHICH WAS ACCEPTABLE AND TAXIED BACK AND TOOK OFF. THE NEXT APCH THE STUDENT TOUCHED DOWN AND BOUNCED. ON THE NEXT TOUCHDOWN THE ACFT SWERVED TO THE L. I TOOK CTL OF THE ACFT AND KEPT IT FROM LEAVING THE RWY WITH THE RUDDER AND BRAKES. I ALSO APPLIED FULL NOSE UP ELEVATOR TO GET THE TAIL DOWN. AS I STRAIGHTENED THE ACFT, THE TAIL STARTED TO RISE. I STILL HAD THE BRAKES ON. THE ACFT CONTINUED UP AND OVER ON ITS NOSE AND STOPPED ON ITS BACK. WE WERE IN HARNESSES AND WERE UNHURT. SHORTLY AFTER THE INCIDENT, THE WIND TEE ON THE RWY SHOWED A TAIL WIND. THINGS I COULD HAVE DONE: (1) GOT OFF THE BRAKE (I HAVE HAD GOOD RESULTS PRIOR USING BRAKE AND BACK PRESSURE IN SUCH SITUATIONS BUT THE OWNER HAD JUST REWORKED THE BRAKES). (2) ADDED PWR AFTER I HAD REGAINED CTL OF THE ACFT. THE FAA CLASSIFIED THE EVENT AS AN INCIDENT.
