Narrative:
My student pilot, on his initial supervised solo landing, departed the runway on landing rollout. All training done in small aircraft type. We had been in the pattern for 1.2 hours. The sequence for lndgs was 2 touch-and-goes, 1 full-stop, and then I would taxi back and allow him to relax. He made 9 lndgs in this sequence. On most of his lndgs I reminded him to pull power all the way off after touchdown. On 2 of his lndgs, the aircraft swerved to the right, but he recovered. The wind was reported to be 350 at 5 on our initial dual taxi, and the windsocks had not changed their direction or lift, and the unicom operator had reported the wind as light and variable to incoming traffic, so we used runway 28, the normal light wind runway of 6402 ft for all lndgs. Following our 9 dual lndgs, I briefed him to do touch-and-goes only if he was comfortable, but if not comfortable to do full stop lndgs, with taxi-backs, whereupon I directed him to make 3 lndgs, and I got out of the plane. He did his solo takeoff, flew the pattern, and touched down relatively flat, but on the main gear. After touchdown, the right wing rose, lifting the right main off the ground. The airplane veered right, departed the runway, and headed back toward the runway before stopping. After the right wing had been raised for 2-3 seconds, I called 'right aileron and left rudder' into the handheld VHF I had, and as the aircraft slowed, I called 'mixture idle cut-off' 2 or 3 times into the handheld. There were no injuries and no aircraft damage. My theory on the cause of the aircraft departing the runway is that the student carried 1200-1500 RPM on the engine after touchdown without reducing power, the mild crosswind lifted the wing and the student did not take appropriate action to correct the situation. The cause of his not taking appropriate action was not enough crosswind training and not sufficient training on aerodynamics of the landing phase.

Title: STUDENT PLT ON FIRST SOLO EXPERIENCES RWY EXCURSION UPON LNDG.
Narrative: MY STUDENT PLT, ON HIS INITIAL SUPERVISED SOLO LNDG, DEPARTED THE RWY ON LNDG ROLLOUT. ALL TRAINING DONE IN SMA TYPE. WE HAD BEEN IN THE PATTERN FOR 1.2 HRS. THE SEQUENCE FOR LNDGS WAS 2 TOUCH-AND-GOES, 1 FULL-STOP, AND THEN I WOULD TAXI BACK AND ALLOW HIM TO RELAX. HE MADE 9 LNDGS IN THIS SEQUENCE. ON MOST OF HIS LNDGS I REMINDED HIM TO PULL POWER ALL THE WAY OFF AFTER TOUCHDOWN. ON 2 OF HIS LNDGS, THE ACFT SWERVED TO THE RIGHT, BUT HE RECOVERED. THE WIND WAS REPORTED TO BE 350 AT 5 ON OUR INITIAL DUAL TAXI, AND THE WINDSOCKS HAD NOT CHANGED THEIR DIRECTION OR LIFT, AND THE UNICOM OPERATOR HAD REPORTED THE WIND AS LIGHT AND VARIABLE TO INCOMING TFC, SO WE USED RWY 28, THE NORMAL LIGHT WIND RWY OF 6402 FT FOR ALL LNDGS. FOLLOWING OUR 9 DUAL LNDGS, I BRIEFED HIM TO DO TOUCH-AND-GOES ONLY IF HE WAS COMFORTABLE, BUT IF NOT COMFORTABLE TO DO FULL STOP LNDGS, WITH TAXI-BACKS, WHEREUPON I DIRECTED HIM TO MAKE 3 LNDGS, AND I GOT OUT OF THE PLANE. HE DID HIS SOLO TKOF, FLEW THE PATTERN, AND TOUCHED DOWN RELATIVELY FLAT, BUT ON THE MAIN GEAR. AFTER TOUCHDOWN, THE RIGHT WING ROSE, LIFTING THE RIGHT MAIN OFF THE GND. THE AIRPLANE VEERED RIGHT, DEPARTED THE RWY, AND HEADED BACK TOWARD THE RWY BEFORE STOPPING. AFTER THE RIGHT WING HAD BEEN RAISED FOR 2-3 SECONDS, I CALLED 'RIGHT AILERON AND LEFT RUDDER' INTO THE HANDHELD VHF I HAD, AND AS THE ACFT SLOWED, I CALLED 'MIXTURE IDLE CUT-OFF' 2 OR 3 TIMES INTO THE HANDHELD. THERE WERE NO INJURIES AND NO ACFT DAMAGE. MY THEORY ON THE CAUSE OF THE ACFT DEPARTING THE RWY IS THAT THE STUDENT CARRIED 1200-1500 RPM ON THE ENGINE AFTER TOUCHDOWN WITHOUT REDUCING POWER, THE MILD XWIND LIFTED THE WING AND THE STUDENT DID NOT TAKE APPROPRIATE ACTION TO CORRECT THE SITUATION. THE CAUSE OF HIS NOT TAKING APPROPRIATE ACTION WAS NOT ENOUGH XWIND TRAINING AND NOT SUFFICIENT TRAINING ON AERODYNAMICS OF THE LNDG PHASE.
