## Discrepancy

AFTER SELECTING (GEAR DOWN), PILOT WAS UNABLE TO GET A GREEN LIGHT FOR RT MLG, IN EITHER NORMAL OR EMERGENCY EXTENSIONS.  GROUND OBSERVERS ADVISED RMLG WAS DOWN AND IB GEAR DOORS WERE OPEN.  UNEVENTFUL LANDING FOLLOWED.  INVESTIGATION REVEALED RMLG DOWNLOCK SWITCH FAILED ELECTRICALLY.   SWITCH WAS REPLACED, SEVERAL GEAR CYCLES ON JACKS.  AIRCRAFT TEST FLOWN, SATISFACTORY.  (K)
