Narrative:
During student training in an small aircraft a for complex requirements in commercial curriculum I requested a touch and go upon landing, were as the student reached toward the throttle and instead lifted the landing gear lever. I immediately lowered the gear lever but the right main had already began retraction. The nose gear and left main remained down and locked, and the aircraft slid to a stop just off the right side of the runway. Damage was minimal with most resulting from collision with a runway light. The propeller or engine received no damage due to the nose gear and left main remaining down. Although the student's last 30 hours (including 1.6 in the small aircraft a) were in small aircraft B with manual flap levers I believe the student lifted the 'flaps' which was really the gear. Since I believe it is impractical to guard the landing gear lever during all ground operations, which defeats the purpose of complex training, a possible prevention measure would be to use a system where the student calls out an operation and the instrument verifies it. In this case the student would have called 'flaps' and I would have been able to yell no!

Title: TRAINING IN COMPLEX ACFT. AFTER LNDG STUDENT RETRACTED GEAR INSTEAD OF FLAPS. INSTRUCTOR REACTED QUICKLY BUT RIGHT MAIN RETRACTED.
Narrative: DURING STUDENT TRNING IN AN SMA A FOR COMPLEX REQUIREMENTS IN COMMERCIAL CURRICULUM I REQUESTED A TOUCH AND GO UPON LNDG, WERE AS THE STUDENT REACHED TOWARD THE THROTTLE AND INSTEAD LIFTED THE LNDG GEAR LEVER. I IMMEDIATELY LOWERED THE GEAR LEVER BUT THE R MAIN HAD ALREADY BEGAN RETRACTION. THE NOSE GEAR AND L MAIN REMAINED DOWN AND LOCKED, AND THE ACFT SLID TO A STOP JUST OFF THE R SIDE OF THE RWY. DAMAGE WAS MINIMAL WITH MOST RESULTING FROM COLLISION WITH A RWY LIGHT. THE PROP OR ENG RECEIVED NO DAMAGE DUE TO THE NOSE GEAR AND L MAIN REMAINING DOWN. ALTHOUGH THE STUDENT'S LAST 30 HRS (INCLUDING 1.6 IN THE SMA A) WERE IN SMA B WITH MANUAL FLAP LEVERS I BELIEVE THE STUDENT LIFTED THE 'FLAPS' WHICH WAS REALLY THE GEAR. SINCE I BELIEVE IT IS IMPRACTICAL TO GUARD THE LNDG GEAR LEVER DURING ALL GND OPS, WHICH DEFEATS THE PURPOSE OF COMPLEX TRNING, A POSSIBLE PREVENTION MEASURE WOULD BE TO USE A SYS WHERE THE STUDENT CALLS OUT AN OPERATION AND THE INSTR VERIFIES IT. IN THIS CASE THE STUDENT WOULD HAVE CALLED 'FLAPS' AND I WOULD HAVE BEEN ABLE TO YELL NO!
