## Discrepancy

ON TAKEOFF, PILOT SELECTED GEAR UP.  RED UNSAFE LIGHT REMAINED ILLUMINATED.  PILOT RETURNED TO BASE, PUMPED GEAR DOWN BY HAND.  LANDED WITHOUT INCIDENT.  RIGHT MAIN INNER GEAR DOOR ACTUATOR UP-LINE FITTING WAS SNAPPED IN HALF.  DURING GEAR INSPECTION, OBSERVATIONS SHOULD BE MADE TO ENSURE TIRE OR BRAKE PARTS DO NOT ENTANGLE HYDRAULIC LINES.
