## Discrepancy

(CAN) STUDENT AND INSTRUCTOR WERE PERFORMING A WALK AROUND OF THE AIRCRAFT BEFORE GOING FOR A LESSON.  STUDENT SELECTED FLAPS DOWN THEY STARTED TO GO DOWN THEN THE FLAPS STOPPED MOVING BUT THE MOTOR KEPT RUNNING.  FLAP MOTOR WAS REMOVED AND IT WAS FOUND THAT THE COUPLING BETWEEN THE MOTOR AND THE ACTUATOR HAD BROKEN.  NEW COUPLING WAS INSTALLED AND THE FLAPS WORKED CORRECTLY.
