## Discrepancy

THE RIGHT MAIN LANDING GEAR WOULD NOT EXTEND NORMALLY.  CHECKLIST PROCEDURES FOLLOWED, GEAR WAS MANUALLY EXTENDED (IE CRANKED DOWN).  NORMAL INDICATIONS APPEARED AFTER MANUAL EXTENSION.  LANDING UNEVENTFUL.  INSTALLED 3000 PSI GAUGE TO UPLINE OF GEAR ACTUATOR AND FOUND ZERO PRESSURE.  REPLACED DOOR SEQUENCE VALVE, NO HELP.  REPLACED RT GEAR DOOR ACTUATOR PER M/M.  GEAR RETRACTS AND EXTENDS NORMALLY.  ALL INDICATIONS GOOD.
