## Discrepancy

FLIGHT 5953, PHL TO CLE - IMMEDIATELY AFTER TAKEOFF THE FLIGHT CREW RECEIVED A LANDING GEAR AIR/GROUND DISAGREE MESSAGE AND THE LANDING GEAR LEVER WOULD NOT GO UP.  THE APPLICABLE CHECKLISTS WERE FOLLOWED AND THE AIRCRAFT RETURNED TO PHL AND LANDED WITHOUT INCIDENT.  MAINTENANCE CLEANED AND RE-SECURED THE LANDING GEAR PROX SWITCHES AND PERFORMED A FUNCTIONAL CHECK OF THE LANDING GEAR CONTROL LEVER IAW TASK 32-32-00-700-802-A AND THE LANDING GEAR OPERATED NORMALLY DURING TEST FLIGHT.
