What was found
(CAN) DURING LANDING GEAR SWINGS TO RECTIFY GEAR INDICATION DEFECT, HYDRAULIC FLUID WAS FOUND LEAKING FROM THE NR 1 MLG HYDRAULIC ACTUATOR, OZONE P2329-3. UPON INVESTIGATION, THE ACTUATOR BODY WAS FOUND CRACKED ALONG THE SEAM BETWEEN THE INLET AND OUTLET PORTS. IF NOT CORRECTED THIS COULD HAVE LEAD TO POSSIBLE FAILURE OF THE ACTUATOR AND AT LEAST THE POSSIBILITY OF ENOUGH FLUID LOSS TO CREATE AN UNSAFE GEAR RETRACTION/EXTENSION CONDITION. ACTUATOR WAS REPLACED.
