## Discrepancy

(CAN) AFTER LOSS OF C-SYSTEM HYDRAULIC FLUID, CREW INITIATED A MANUAL GEAR EXTENSION RESULTING IN A LARGE AUDIBLE BANG FROM THE RIGHT MLG.  AIRCRAFT LANDED WITHOUT INCIDENT.  INVESTIGATION REVEALED THAT THE RIGHT LANDING GEAR ACTUATOR SHEARED, JURY DRAG BRACE SHEARED, AND INNER DOOR DAMAGE.  DUE TO ACTUATOR DAMAGE, THE GEAR HAD NO SNUBBING ON EXTENSION AND STRUCK THE DOOR AND UPON REACHING THE END OF TRAVEL, SHEARED THE JURY BRACE BOLT.  ACTUATOR AND JURY BRACE BOLT REPLACED.
