## Discrepancy

CREW REPORTS GEAR DISAGREE MSG.  LOWERED GEAR & DID NOT GET NOSE GEAR GREEN. ACCOMPLISHED ALT GEAR EXTENSION STILL NO GREEN.  ALSO FLIGHT ATTENDANT REPORTED LOUD GRINDING AT INITIAL GEAR RETRACTION.  R & R GEAR DOOR ACTUATOR, LOCK ACTUATOR & SEQUENCE VLV.  ACCOMPLISHED GEAR SWING SEVERAL TIMES WITH INSPECTORS PRESENCE.  THE RESULTS ARE GOOD, NO GRINDING NOISE AS DESCRIBED.  RII INSPECTION & FLIGHT TESTED SATISFACTORY.
