## Discrepancy

AFTER LANDING WHEN NR 1 PROP WAS FEATHERED, CREW REPORTED LOSING NOSE WHEEL STEERING AND THE NORMAL BEAKES. CREW USED PARK BRAKE TO STOP AIRCRAFT. CREW OBSERVED MAIN AND STANDBY HYDRAULIC PRESSURE AT LESS THAN 1800 PSI FOLLOWED BY NR 1 ENGINE HYDRAULIC PUMP CAUTION LIGHT ILLUMINATING. AFTER 10 SECONDS ALL INDICATIONS RETURNED TO NORMAL. MAINTENANCE COULD NOT DUPLICATE THE DISCREPANCY.
