Narrative:

After 3 1/2 hours and 4 previous flts I was completing a rental check/complex endorsement for my student. After landing at renton, the aircraft was slowing down on the rollout and transitioning to a takeoff roll. We previously agreed I would raise the flaps to 10 degrees from 30 degrees. As I did this, my student pushed in the carburetor heat control and raised the gear lever. The aircraft immediately dropped its nose to the ground (C172 rg). This happened very quickly and left no time to change the gear lever back to the down position. As the plane slid to a stop, I pulled the mixture control out and turned the fuel off. When the aircraft stopped, I turned the master switch off and put the gear selector down to prevent any further retraction and damage. We both left the aircraft and the runway. The fire department came and helped us remove the aircraft from the runway into a tie-down slot. My student has been thoroughly briefed on not to raise the gear up at all while on the ground. Also the shape of the gear handle has been pointed out to the student. Nothing previous to this incident indicated that this student would have any tendencies to raise the gear up on the ground. It seems that although we have done 6 lndgs in prior flts, the pressure of a touch and go is a factor in this incident. Also the possibility of a squat-switch (nose gear) may not have functioned properly.

Title: STUDENT PLT CHKING OUT IN COMPLEX ACFT RAISES GEAR HANDLE ON THE RWY.

Narrative: AFTER 3 1/2 HRS AND 4 PREVIOUS FLTS I WAS COMPLETING A RENTAL CHK/COMPLEX ENDORSEMENT FOR MY STUDENT. AFTER LNDG AT RENTON, THE ACFT WAS SLOWING DOWN ON THE ROLLOUT AND TRANSITIONING TO A TKOF ROLL. WE PREVIOUSLY AGREED I WOULD RAISE THE FLAPS TO 10 DEGS FROM 30 DEGS. AS I DID THIS, MY STUDENT PUSHED IN THE CARB HEAT CTL AND RAISED THE GEAR LEVER. THE ACFT IMMEDIATELY DROPPED ITS NOSE TO THE GND (C172 RG). THIS HAPPENED VERY QUICKLY AND LEFT NO TIME TO CHANGE THE GEAR LEVER BACK TO THE DOWN POS. AS THE PLANE SLID TO A STOP, I PULLED THE MIXTURE CTL OUT AND TURNED THE FUEL OFF. WHEN THE ACFT STOPPED, I TURNED THE MASTER SWITCH OFF AND PUT THE GEAR SELECTOR DOWN TO PREVENT ANY FURTHER RETRACTION AND DAMAGE. WE BOTH LEFT THE ACFT AND THE RWY. THE FIRE DEPT CAME AND HELPED US REMOVE THE ACFT FROM THE RWY INTO A TIE-DOWN SLOT. MY STUDENT HAS BEEN THOROUGHLY BRIEFED ON NOT TO RAISE THE GEAR UP AT ALL WHILE ON THE GND. ALSO THE SHAPE OF THE GEAR HANDLE HAS BEEN POINTED OUT TO THE STUDENT. NOTHING PREVIOUS TO THIS INCIDENT INDICATED THAT THIS STUDENT WOULD HAVE ANY TENDENCIES TO RAISE THE GEAR UP ON THE GND. IT SEEMS THAT ALTHOUGH WE HAVE DONE 6 LNDGS IN PRIOR FLTS, THE PRESSURE OF A TOUCH AND GO IS A FACTOR IN THIS INCIDENT. ALSO THE POSSIBILITY OF A SQUAT-SWITCH (NOSE GEAR) MAY NOT HAVE FUNCTIONED PROPERLY.
