## Discrepancy

WHEN GEAR WAS EXTENDED, LT MAIN AND NOSE EXTENDED NORMALLY.  RT MAIN GEAR INDICATOR TURNED YELLOW AND THEN WE GOT A RED "GEAR UNSAFE" INDICATION.  WE INTIATED A GO-AROUND AND RAN CHECKLIST.  UPON CYCLING THE GEAR HANDLE, WE GOT ALL 3 GEAR GREEN INDICATIONS.   REMOVED FAILED RT MAIN GEAR ACTUATOR AND INSTALLED A REPAIRED ACTUATOR. ACCOMPLISHED OPS & LEAK CHECKS. ALL CHECKS SATISFACTORY.  IAW CMP 321004 AND MM 32-10-20 & 32-10-15.
