## Discrepancy

ON APPROACH TO KLUK THE PILOT SELECTED THE GEAR DOWN AND DID NOT GET A GREEN INDICATION FOR THE LEFT MAIN LANDING GEAR. THE AIRCRAFT LANDED SAFELY, AND IT WAS FOUND THAT THE INTERNAL DOWN LOCK INDICATOR SWITCH IN THE LEFT MAIN LANDING GEAR STRUT HAD MALFUNCTIONED.  THE STRUT HAD BEEN REPLACED 6 CYCLES BEFORE FAILURE OF THE INTERNAL SWITCH, AND WAS AN OVERHAULED STRUT, NOT NEW.
