## Discrepancy

AIRCRAFT WAS GROUNDED: AFTER TAKE OFF LANDING GEAR DID NOT COME UP AND A LANDING GEAR DISAGREE ECAM MESSAGE. THE FLIGTH CREW RECYCLED THE GEAR TO UP POSITION AND GEAR CAME UP. MAINTENANCE ACCOMPLISHED A LANDIG GEAR SYSTEM BITE CHECK AND NOTED THAT THERE WERE FAULT MESSAGES FOR NOSE LANDING GEAR PROXIMITY SENSORS 24GA (AALA202504145504) AND 25GA (). MAINTENANCE REPLACED BOTH PROXIMITY SENSORS PER AMM 32-31-73. MAINTENANCE ALSO FOUND THE NOSE LANDING GEAR LEVER BRACKET DAMAGED AND REPLACED IT PER AMM 32-21-45.(AALA202504147221) A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED.
