Narrative:
A300 dispatched with 1 pack summer operations. After pushback APU bleed leak light illuminated. Shut off APU, bleed leak light went out. Reset started engines. Temperature in cabin after start 98 degrees F. 45 mins later landing mia temperature 96 degrees F. Before departing mco talked to dispatch about taking aircraft OTS in mia. Maintenance verified that the aircraft had a blown duct 1 pack before departing mco. The combination of the APU bleed leak along with 1 pack on a hot summer day is deadly. Not a good idea. Please consider this unacceptable for passenger operation. The plane will pressurize fine up to 310. The temperature control is the problem. Also reduced air flow into the equipment bay with 100 air will cause instrumentation problems. On arrival at mia, aircraft scheduled to fly on to sju. Refused to take the plane on to sju.

Title: AN A300 CREW, DISPATCHED FROM MCO WITH 1 AIR CONDITIONING PACK INOP, EXPERIENCED AN 'APU BLEED LEAK' DURING PUSHBACK, AFFECTING TEMP CTL.
Narrative: A300 DISPATCHED WITH 1 PACK SUMMER OPS. AFTER PUSHBACK APU BLEED LEAK LIGHT ILLUMINATED. SHUT OFF APU, BLEED LEAK LIGHT WENT OUT. RESET STARTED ENGINES. TEMP IN CABIN AFTER START 98 DEGS F. 45 MINS LATER LNDG MIA TEMP 96 DEGS F. BEFORE DEPARTING MCO TALKED TO DISPATCH ABOUT TAKING ACFT OTS IN MIA. MAINT VERIFIED THAT THE ACFT HAD A BLOWN DUCT 1 PACK BEFORE DEPARTING MCO. THE COMBINATION OF THE APU BLEED LEAK ALONG WITH 1 PACK ON A HOT SUMMER DAY IS DEADLY. NOT A GOOD IDEA. PLEASE CONSIDER THIS UNACCEPTABLE FOR PAX OP. THE PLANE WILL PRESSURIZE FINE UP TO 310. THE TEMP CTL IS THE PROB. ALSO REDUCED AIR FLOW INTO THE EQUIP BAY WITH 100 AIR WILL CAUSE INSTRUMENTATION PROBS. ON ARR AT MIA, ACFT SCHEDULED TO FLY ON TO SJU. REFUSED TO TAKE THE PLANE ON TO SJU.
