Narrative:

I was flying as a flight instructor with an advanced pre- solo student. We were practicing takeoffs and lndgs. We needed to use a small amount of sideslip. The wind was 25 degrees from the left of the runway direction at approximately 10 KTS. My student was approaching the skill level to solo, and I therefore was becoming more comfortable flying with this student. On our 4TH landing of the day, my student landed with the left main on the centerline of the runway. We started to track to the right, possibly pushed by a gust of wind. I tried to talk my student into straightening the direction of the airplane, however the right main gear went off the runway. A split-second before, I started to apply the necessary control inputs to keep the main gear on the runway, but I was a little late. I continued applying the necessary control inputs and successfully returned the airplane fully on the runway. There were no injuries. A contributing factor was my comfort level with my advanced pre-solo student, and therefore confidence that my student would successfully keep the airplane fully on the runway.

Title: INSTRUCTOR AND SPI HAVE R MAIN GEAR OFF RWY ON LNDG ROLLOUT.

Narrative: I WAS FLYING AS A FLT INSTRUCTOR WITH AN ADVANCED PRE- SOLO STUDENT. WE WERE PRACTICING TKOFS AND LNDGS. WE NEEDED TO USE A SMALL AMOUNT OF SIDESLIP. THE WIND WAS 25 DEGS FROM THE L OF THE RWY DIRECTION AT APPROX 10 KTS. MY STUDENT WAS APCHING THE SKILL LEVEL TO SOLO, AND I THEREFORE WAS BECOMING MORE COMFORTABLE FLYING WITH THIS STUDENT. ON OUR 4TH LNDG OF THE DAY, MY STUDENT LANDED WITH THE L MAIN ON THE CTRLINE OF THE RWY. WE STARTED TO TRACK TO THE R, POSSIBLY PUSHED BY A GUST OF WIND. I TRIED TO TALK MY STUDENT INTO STRAIGHTENING THE DIRECTION OF THE AIRPLANE, HOWEVER THE R MAIN GEAR WENT OFF THE RWY. A SPLIT-SECOND BEFORE, I STARTED TO APPLY THE NECESSARY CTL INPUTS TO KEEP THE MAIN GEAR ON THE RWY, BUT I WAS A LITTLE LATE. I CONTINUED APPLYING THE NECESSARY CTL INPUTS AND SUCCESSFULLY RETURNED THE AIRPLANE FULLY ON THE RWY. THERE WERE NO INJURIES. A CONTRIBUTING FACTOR WAS MY COMFORT LEVEL WITH MY ADVANCED PRE-SOLO STUDENT, AND THEREFORE CONFIDENCE THAT MY STUDENT WOULD SUCCESSFULLY KEEP THE AIRPLANE FULLY ON THE RWY.
