## Discrepancy

(CAN) DURING PHASE 5 INSPECTION CORROSION WAS NOTICED AROUND THE TRUNNION INNER PINS.AFTER MUCH DIFFICULTY THE PINS WERE REMOVED AND CORROSION WAS FOUND ON THE INSIDE OF THE BUSHINGS,SEIZING THE PINS. THE PINS ARE STACKED TO THE TRUNNION AND BUSHING WITH ROLL PINS. THE GEAR IS REQUIRED TO BE REMOVED AT 25800 LANDINGS, BUT, THERE IS NO REQUIREMENT TO REMOVE AND INSPECT THE PINS.
