What was found
THE CREW DIVERTED THE FLIGHT DUE TO AN "AFT CARGO FIRE" INDICATION DURING CLIMB OUT, AT APPROXIMATELY 14K. CREW COMPLIED WITH QRH PROCEDURES AND DISCHARGED THE CARGO FIRE BOTTLE. MAINTENANCE PLACED THE CARGO COMPARTMENTS AND FIRE DETECTION SYSTEM ON MEL AND THE FLIGHT CONTINUED. THE CARGO FIRE EXTINGUISHING BOTTLES WERE REPLACED ALONG WITH THE COCKPIT CONTROL PANEL DUE TO A LOOSE AFT COMPARTMENT SELECTOR SWITCH. THE CARGO FIRE INDICATION SYSTEM WAS FOUND OPERATIONAL.
