## Discrepancy

UPON APPROACH TO LNG, GEAR LOWERED, GREEN DOWN AND LOCKED LIGHT DID NOT COME ON.  CYCLED GEAR, STILL NO GREEN LIGHT.  GEAR VISUALLY APPEARED DOWN AND LOCKED (IN POSITION).  LANDED WITH NO PROBLEMS.  FOUND RT MLG DOWN AND LOCKED SWITCH CORRODED AND INTERMITTENT.  REPLACED SWITCH WITH NEW, P/N S2088-1, SWITCH.  NOTE:  SWITCH IS IN OPEN GEAR WELL AND IN EXHAUST PATH.
