## Analysis

THE STUDENT PLT WAS TAXIING FOR TAKEOFF WHEN SHE APPLIED RIGHT BRAKE WHERE A RIGHT TURN WAS NEEDED, HOWEVER, THE ACFT DID NOT TURN AS IT SHOULD. THE INSTRUCTOR PLT THEN TOOK CONTROL OF THE ACFT. HE APPLIED RIGHT BRAKE, THEN BOTH BRAKES, BUT HAD NEGATIVE RESULTS. AT THAT POINT, THE ACFT WAS HEADED TOWARD A PORTABLE BUILDING. THE INSTRUCTOR TURNED OFF THE MAGNETO SWITCHES JUST BEFORE THE ACFT HIT THE BUILDING. THE INSTRUCTOR REPORTED THAT BOTH BRAKES WERE WORN, A PUCK WAS MISSING FROM THE LEFT BRAKE & 1/2 OF THE RIGHT BRAKE ROTOR/DISK HAD SEPARATED AT THE BASE.
