## Discrepancy

(CAN)  ROLLER BEARING WITH NLG DOORS FULLY CLOSED SHOULD FALL WITHIN ITS MECHANICAL CAM-LOCK  WHEN FUNCTIONING NORMALLY. WHEN HYDS ARE REMOVED, RETRACT ACTUATOR WILL RELAX AND CAM-LOCKED ROLLER BEARING WILL KEEP NLG DOOR FULLY CLOSED, PREVENTING FROM FALLING 'OPEN'.  IF PIVOT BOLT BECOMES CORRODED AND RESTRICTS MOVEMENT OF ITS SPRING-LOADED PIVOT LEVER.  ROLLER BEARING CAN HANG-UP AND NOT FALL INTO ITS CAM-LOCK SLOT. WHEN HYDRAULICS ARE REMOVED AND DOOR RETRACT ACTUATOR RELAXES, DOORS WILL DROP OPEN.
