## Discrepancy

(CAN) PILOT INBOUND FOR LANDING & SELECTED GEAR DOWN. REPORTED THAT GEAR DID NOT EXTEND & GEAR MOTOR CONTINUED RUNNING.  BEGAN EMERGENCY EXTENSION OF GEAR WITH HAND PUMP BUT NO PRESSURE BUILDING ON HAND PUMP.  SEVERAL PROCEEDURES WERE CARRIED OUT BY PILOT & GROUND CREW, WITH NO SUCCESS. ON FLY BY IT WAS NOTED NOSE GEAR EXTENDED & SEEMED LOCKED, BUT MAIN GEAR HALFWAY EXTENDED. PILOT FINALLY EXECUTED GEAR UP LDG.  ON INSPECTION OF MLG, IT WAS FOUND THAT REAR LT MLG DOOR ACTUATOR CYLINDER SEPARATED FROM PISTON ROD. PILOT REPORTED THAT HYDRAULIC FLUID AT NORMAL LEVEL.
