## Discrepancy

UPON GEAR EXTENSION, ON APPROACH, THE CREW DID NOT GET A GREEN SAFE RT MLG INDICATION.  THE CREW DID A LOW APPROACH TO SEE IF THE TOWER COULD CONFIRM.  THE CREW MISSED THE APPROACH, RAN THE APPROPRIATE CHECKLIST & DIVERTED.  AFTER ACCOMPLISHING THE APPROPRIATE CHECKLIST, THE CREW RECEIVED A THREE GREEN DOWN & LOCKED INDICATION & LANDED WITHOUT INCIDENT.  FOUND AIR IN THE SYS CAUSING THE RT GEAR TO EXTEND VERY SLOWLY.  BLED AIR FROM THE LG HYD SYS.  OPERATIONAL CHECKED GOOD.
