## Discrepancy

AIRCRAFT WAS GROUNDED: FLIGHT CREW REPORTED THAT THE LANDING GEAR DOORS FAILED TO RETRACT AFTER TAKE OFF.  FLIGHT CREW FOLLOWED ECAM PROCEDURES AND CYCLED THE GEAR HANDLE WHICH RESULTED IN THE GEAR AND DOORS RETRACTING SUCCESSFULLY. THE AIRCRAFT CONTINUED TO IAH AND THE GEAR CAME DOWN NORMALLY BUT AFTER TOUCHDOWN A LANDING GEAR SYSTEM DISAGREE MESSAGE DISPLAYED ON THE ECAM. MAINTENANCE REPLACED THE FLIGHT / GROUND SENSING MECHANISM LEVER PER AMM 32-21-45-400-803-A AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK.
