Narrative:

Landing on runway 32, student pilot was doing touch and goes. On my first pass, when I landed to do my touch and go, the plane veered off to the left side of the runway. I applied the brakes to slow down and to get back to the centerline. When I applied the brakes, the right brake locked up, causing me (student pilot) to veer off runway 32 and onto the grass. There was no damage to the aircraft, to the runway lights and runway. I strongly believe that when the brakes locked up, I lost control of the aircraft and veered off to the runway. When getting back to the centerline, the adding of the brakes at a higher speed (less than 40 KTS), caused the momentum to stop the plane, much harder to stop. The brakes were locked when I was veering off the runway. To prevent this from happening again, student pilots should be taught by their instructors, not to apply full brakes when doing touch and goes.

Title: SMA STUDENT PLT LOST DIRECTIONAL CTL DURING TOUCH AND GO LNDG RESULTING IN GOING OFF THE SIDE OF THE RWY INTO THE GRASS. THERE WAS NO DAMAGE TO THE ACFT OR ARPT RWY LIGHTING.

Narrative: LNDG ON RWY 32, STUDENT PLT WAS DOING TOUCH AND GOES. ON MY FIRST PASS, WHEN I LANDED TO DO MY TOUCH AND GO, THE PLANE VEERED OFF TO THE L SIDE OF THE RWY. I APPLIED THE BRAKES TO SLOW DOWN AND TO GET BACK TO THE CTRLINE. WHEN I APPLIED THE BRAKES, THE R BRAKE LOCKED UP, CAUSING ME (STUDENT PLT) TO VEER OFF RWY 32 AND ONTO THE GRASS. THERE WAS NO DAMAGE TO THE ACFT, TO THE RWY LIGHTS AND RWY. I STRONGLY BELIEVE THAT WHEN THE BRAKES LOCKED UP, I LOST CTL OF THE ACFT AND VEERED OFF TO THE RWY. WHEN GETTING BACK TO THE CTRLINE, THE ADDING OF THE BRAKES AT A HIGHER SPD (LESS THAN 40 KTS), CAUSED THE MOMENTUM TO STOP THE PLANE, MUCH HARDER TO STOP. THE BRAKES WERE LOCKED WHEN I WAS VEERING OFF THE RWY. TO PREVENT THIS FROM HAPPENING AGAIN, STUDENT PLTS SHOULD BE TAUGHT BY THEIR INSTRUCTORS, NOT TO APPLY FULL BRAKES WHEN DOING TOUCH AND GOES.
