## Discrepancy

AIRCRAFT WAS NOT GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO RSW DUE TO THE FLIGHT CREW REPORTING THAT THE AFT CARGO DOOR INDICATED OPEN ONCE AIRBORNE. ALL DOORS INDICATED CLOSED AT PUSH BACK THROUGH TAKEOFF. THE AIRCRAFT LANDED SAFELY AT RSW AND TAXIED TO THE GATE UNDER ITS OWN POWER. MAINTENANCE REPLACED PROXIMITY SENSOR 32WV AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECKS PER AMM 52-71-12.
