## Discrepancy

ON APPROACH HAD LT MLG UNSAFE INDICATION.  A/C LANDED WITH GEAR DOORS DOWN DUE TO ALT GEAR EXTENSION.  A/C WAS FERRIED TO BOS FOR GEAR MTC.  IN BOS CHECKED OUT ALL 3 LT GEAR PROX SWITCHES WITH ELEC TEST KIT.  ALL CHECKS OK.  SHOOK DOWN WIRING HARNESS FOR ALL 3 PROX SWITCH CHECKS.  JACKED AND CYCLED GEAR.  ALL CHECKS OK.  REPLACED PSEU PER MM.
