Narrative:

I was on an instruction flight with a pre-solo student. After we completed our lesson, we returned to land. On our final approach, we had a crosswind of approximately 10 KTS, 60 degrees off the nose. I thought the conditions were within the student's capabilities. The student began to flare the airplane too high above the runway, and I coached him to lower the nose slightly, until we were at the proper flaring ht. This done, we landed, but the student still had the left rudder depressed on the ground roll, causing us to veer toward the edge of the runway. At this point, I took the controls. However, we still continued toward the edge of the runway into the snow. My primary concern was to get the airplane stopped safely. In the future, I will make sure I keep my hand on the throttle (over the students) during lndgs, so I can execute a 'go around' and take full control of the landing if the student's approach and flare are not done properly.

Title: INSTRUCTOR DOES NOT TAKE CTL FROM STUDENT ON LNDG WITH XWIND IN C172 TRAINING LESSON, AND WITH THE STUDENT DEPRESSING THE RUDDER, INCURS A RWY EXCURSION.

Narrative: I WAS ON AN INSTRUCTION FLT WITH A PRE-SOLO STUDENT. AFTER WE COMPLETED OUR LESSON, WE RETURNED TO LAND. ON OUR FINAL APCH, WE HAD A XWIND OF APPROX 10 KTS, 60 DEGS OFF THE NOSE. I THOUGHT THE CONDITIONS WERE WITHIN THE STUDENT'S CAPABILITIES. THE STUDENT BEGAN TO FLARE THE AIRPLANE TOO HIGH ABOVE THE RWY, AND I COACHED HIM TO LOWER THE NOSE SLIGHTLY, UNTIL WE WERE AT THE PROPER FLARING HT. THIS DONE, WE LANDED, BUT THE STUDENT STILL HAD THE L RUDDER DEPRESSED ON THE GND ROLL, CAUSING US TO VEER TOWARD THE EDGE OF THE RWY. AT THIS POINT, I TOOK THE CTLS. HOWEVER, WE STILL CONTINUED TOWARD THE EDGE OF THE RWY INTO THE SNOW. MY PRIMARY CONCERN WAS TO GET THE AIRPLANE STOPPED SAFELY. IN THE FUTURE, I WILL MAKE SURE I KEEP MY HAND ON THE THROTTLE (OVER THE STUDENTS) DURING LNDGS, SO I CAN EXECUTE A 'GAR' AND TAKE FULL CTL OF THE LNDG IF THE STUDENT'S APCH AND FLARE ARE NOT DONE PROPERLY.
