## Discrepancy

THE BRAKES WENT OUT ON THE GROUND.  THE FLIGHT CREW LOST CONTROL AND HIT ANOTHER AIRCRAFT.  THE RIGHT WING TIP HIT THE RT VERTICAL STABILIZER ON OTHER AC.  MECHANICS WERE DISPATCHED, THE RT WING TIP WAS REMOVED AND REPLACED.  THE BRAKE CONTROL VALVE WAS ALSO REMOVED AND REPLACED AND OPS CHECKED GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
