## Discrepancy

AIRCRAFT REJECTED TAKEOFF AT 50 KTS, STARTED THE TAKEOFF RUN, THE MAIN GEAR STEERING CONFIGURATION LIGHT TURNED ON AND THE ALARM WAS ACTIVATED. MAINTENANCE PERSONNEL INSPECTED BOTH MAIN LANDING GEARS AND DETECTED THE RT SIDE BYPASS VALVE IN UNLOCK POSITION; IT WAS RE-ESTABLISHED TO THE LOCK POSITION AND TESTED IAW MM 32-53-03, ALL CORRECT.
