What was found

LEFT MAIN LANDING GEAR BRAKES WERE LOCKED UP ON LANDING. THE NR 1 AND NR 2 WHEEL AND TIRE ASSEMBLIES WERE DISTROYED. AFTER REPLACING THE WHEELS, NO DEFECTS COULD BE FOUND WITH THE BRAKE SYSTEM. AS A PRECAUTION THE BRAKE CONTROL VALVE WAS REPLACED AS IT WAS THE ONLY COMPONENT THOUGHT TO CREATE THE PROBLEM.
