## Discrepancy

ON APPROACH INTO IND, LANDING GEAR HAD TO BE CYCLED THREE TIMES TO GET A DOWN AND LOCKED INDICATION ON THE RT MAIN GEAR.  THE RED LIGHT REMAINED ON AND A GO-AROUND WAS INITIATED.  AS THE AIRCRAFT PITCHED UP, THE LIGHT EXTINGUISHED AND THE GREEN LIGHT ILLUMINATED.  THE GEAR WAS LEFT EXTENDED ON GO-AROUND, AND AIRCRAFT LANDED WITHOUT INCIDENT.  REPLACED LANDING GEAR ASSY PN 653756822 UNIT PER MM 32-9-211, GROUND CHECK NORMAL.  ALSO, REPLACED RT MAIN GEAR SWITCH PER MM 32-32-0 AS PRECAUTION.  OPS CHECK GOOD.
