## Discrepancy

VIBRATION AND NOISE FROM NOSE GEAR AREA OCCURRED ON GEAR RETRACTION AFTER TAKEOFF.  NOSE GEAR AND RED UNSAFE LIGHT ALSO ILLUMINATED.  RECYCLED GEAR SEVERAL TIMES AND LIGHT REMAINED ON.

IT IS SUSPECTED THAT THE DOOR RELEASE ACTUATOR HAD FAILED.  REPLACED CABLE, ACTUATOR, AND REPAIRED DOOR.  INSPECTED NOSE GEAR PROXIMITY SENSOR FOR ADJUSTMENT AND SECURITY.  ALL CHECKED GOOD.  PERFORMED RETRACTION TEST OF NOSE GEAR SEVERAL TIMES.  NO PROBLEMS WERE FOUND.  AIRCRAFT RETURNED TO SERVICE.
