## Discrepancy

AFTER TAKEOFF WHEN THE GEAR RETRACTION WAS CALLED FOR THE LANDING GEAR HANDLE WAS STUCK IN THE DOWN POSITION. SHORTLY AFTER WE RECEIVED A WOW MISCOMPARE AMBER CAS MESSAGE. THE NOSE GEAR, LEFT MAIN, AND RIGHT MAIN INDICATORS WERE NOT NOTED TO HAVE EVER CHANGED FROM 3 GREEN INDICATIONS. CORRECTIVE ACTION: REMOVED RH MLG SQUAT SWITCH PN S3176-1 AND INSTALLED "NEW" RH MLG SQUAT SWITCH PN S3176-1 REF CE680A AMM32-60-05. OPS CHECK GOOD AT THIS TIME.
