## Discrepancy

WHEN LANDING GEAR WAS SELECTED UP, A POP WAS HEARD AND AFTER GEAR RETRACTION, THE RED UNSAFE LIGHT STAYED ILLUMINATED.  THE GEAR WAS SELECTED DOWN, AND THE AIRCRAFT RETURNED TO THE DEPARTURE AIRPORT.  INSPECTION OF THE LANDING GEAR SHOWED THE NOSE GEAR DOOR ACTUATOR ROD END HAD FAILED. THE EXACT CAUSE OF THE FAILURE IS UNKNOWN, THE ROD END/ACTUATOR WILL BE REPLACED, AND THE DOOR UPLOCKS AND TELEFORCE CABLE RIGGING WILL BE  CHECKED IAW THE FALCON 20 MM.  (X)
