## Discrepancy

AFTER TAKEOFF, CREW REPORTED A LANDING GEAR AIR/GROUND FAIL MESSAGE ON THE EICAS AND THAT THE LANDING GEAR WOULD NOT RETRACT.  MAINTENANCE INSPECTED THE AIRCRAFT AND CLEANED THE MLG WOW PROXIMITY SWITCHES.  A SUBSEQUENT OPERATIONAL CHECK OF THE LANDING GEAR EXTENSION AND RETRACTION SYSTEM PROVED A GOOD FIX AT THAT TIME.
