## Discrepancy

AIRCRAFT RETURNED TO PLATFORM DUE TO DURING TAXING AND AFTER RELEASING PARKING BRAKES, THE 4 ANTI-SKID LIGHTS TURNED ON. AT PLATFORM ANTI-SKID DUAL PRESS CONTROL VALVES CONNECTORS AND SWITCHES S1-130 AND S10-195 WERE CLEANED IAW MM 32-43-05. ANTI-SKID SYSTEM WAS TESTED IAW MM 32-43-00, ALL CORRECT.
