## Discrepancy

SDF FLT 2010 THE CREW REPORTED A LANDING GEAR AIR/GROUND FAIL MESSAGE UPON EXTENDING LANDING GEAR.  MAINTENANCE INSPECTED AND REPLACED THE RIGHT GEAR NR 2 PROXIMITY SWITCH.  ADJUSTED THE GAP ON THE RIGHT GEAR NR 1 PROXIMITY SWITCH AND SERVICED BOTH LEFT AND RIGHT GEARS.  OPERATIONAL CHECKS WERE GOOD.
