Narrative:

After touchdown with the main gear I proceeded with my normal braking sequence, as follows: retract flaps, apply pressure to the brake peddles and pull back on the control wheel (to transfer more of the airplanes weight to the main gear). At this point the airplane veered to the right causing the right main gear to go off the runway for a very short distance. After I was back on the runway I discovered the flaps were still extended 10 degrees (pilot error). With the flaps extended 10 degrees I did not have adequate traction to the main gear and runway. After this landing I accomplished 2 additional lndgs using the described landing technique without any mishap. Please note this was my very first supervised solo flight and I was excited and nervous. I could have added too much right brake peddle pressure which made the situation worse. The distance the right landing gear traveled while off the runway was approximately 15-20 ft.

Title: LOSS OF ACFT CTL DURING LNDG PROC ROLLOUT BY STUDENT PLT. RWY EXCURSION OCCURS.

Narrative: AFTER TOUCHDOWN WITH THE MAIN GEAR I PROCEEDED WITH MY NORMAL BRAKING SEQUENCE, AS FOLLOWS: RETRACT FLAPS, APPLY PRESSURE TO THE BRAKE PEDDLES AND PULL BACK ON THE CTL WHEEL (TO TRANSFER MORE OF THE AIRPLANES WT TO THE MAIN GEAR). AT THIS POINT THE AIRPLANE VEERED TO THE R CAUSING THE R MAIN GEAR TO GO OFF THE RWY FOR A VERY SHORT DISTANCE. AFTER I WAS BACK ON THE RWY I DISCOVERED THE FLAPS WERE STILL EXTENDED 10 DEGS (PLT ERROR). WITH THE FLAPS EXTENDED 10 DEGS I DID NOT HAVE ADEQUATE TRACTION TO THE MAIN GEAR AND RWY. AFTER THIS LNDG I ACCOMPLISHED 2 ADDITIONAL LNDGS USING THE DESCRIBED LNDG TECHNIQUE WITHOUT ANY MISHAP. PLEASE NOTE THIS WAS MY VERY FIRST SUPERVISED SOLO FLT AND I WAS EXCITED AND NERVOUS. I COULD HAVE ADDED TOO MUCH R BRAKE PEDDLE PRESSURE WHICH MADE THE SIT WORSE. THE DISTANCE THE R LNDG GEAR TRAVELED WHILE OFF THE RWY WAS APPROX 15-20 FT.
