## Discrepancy

FLIGHT 5158 UPON APPROACH THE PILOTS REPORTED THAT THE RIGHT MAIN LANDING GEAR WOULD NOT EXTEND. PILOTS PERFORMED A MANUAL EXTENSION. MAINTENANCE CLEANED THE RIGHT HAND DOWNLOCK SWITCH AND PERFORMED SIX LANDING GEAR EXTESNIONS AND RETRACTIONS IAW MM 32-30-00. ALL CHECKS WERE GOOD AND THE FAULT COULD NOT BE DUPLICATED.
