Narrative:

About 5 mins after sterile cockpit (after takeoff) the air conditioning stopped and the cabin started to get warm. Then we started descending. 1 flight attendant went to the cockpit to see what was wrong and tell them it was warm. The captain told the flight attendant to have us situation down until further notice. We did and the first officer was donning his oxygen mask (the flight attendant told us) so we were about to get the oxygen walkarounds down in case we needed them. About that time the oxygen mask compartments opened and we took oxygen from them. Soon after the masks dropped, the captain came on and told us we could discontinue use of oxygen. They turned the plane around and we returned to dallas. On the way back to dallas, we comforted passenger and gave them water. The cabin became very hot. This is unavoidable during a cabin pressurization problem due to the heat from the generators, but it was very uncomfortable. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was an md super 80 and after takeoff the airplane cabin became hotter and hotter. The reporter said the captain deployed the seat emergency oxygen masks due to no cabin pressure. The reporter said the cause of this incident was both air conditioning packs were inoperative and supplied no cabin air.

Original NASA ASRS Text

Title: AN MD SUPER 80 ON INITIAL CLB AT 10000 FT DECLARED AN EMER AND RETURNED TO DFW DUE TO UNABLE TO PRESSURIZE THE CABIN CAUSED BY FAILURE OF THE R AND L AIR CONDITIONING PACKS.

Narrative: ABOUT 5 MINS AFTER STERILE COCKPIT (AFTER TKOF) THE AIR CONDITIONING STOPPED AND THE CABIN STARTED TO GET WARM. THEN WE STARTED DSNDING. 1 FLT ATTENDANT WENT TO THE COCKPIT TO SEE WHAT WAS WRONG AND TELL THEM IT WAS WARM. THE CAPT TOLD THE FLT ATTENDANT TO HAVE US SIT DOWN UNTIL FURTHER NOTICE. WE DID AND THE FO WAS DONNING HIS OXYGEN MASK (THE FLT ATTENDANT TOLD US) SO WE WERE ABOUT TO GET THE OXYGEN WALKAROUNDS DOWN IN CASE WE NEEDED THEM. ABOUT THAT TIME THE OXYGEN MASK COMPARTMENTS OPENED AND WE TOOK OXYGEN FROM THEM. SOON AFTER THE MASKS DROPPED, THE CAPT CAME ON AND TOLD US WE COULD DISCONTINUE USE OF OXYGEN. THEY TURNED THE PLANE AROUND AND WE RETURNED TO DALLAS. ON THE WAY BACK TO DALLAS, WE COMFORTED PAX AND GAVE THEM WATER. THE CABIN BECAME VERY HOT. THIS IS UNAVOIDABLE DURING A CABIN PRESSURIZATION PROB DUE TO THE HEAT FROM THE GENERATORS, BUT IT WAS VERY UNCOMFORTABLE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS AN MD SUPER 80 AND AFTER TKOF THE AIRPLANE CABIN BECAME HOTTER AND HOTTER. THE RPTR SAID THE CAPT DEPLOYED THE SEAT EMER OXYGEN MASKS DUE TO NO CABIN PRESSURE. THE RPTR SAID THE CAUSE OF THIS INCIDENT WAS BOTH AIR CONDITIONING PACKS WERE INOP AND SUPPLIED NO CABIN AIR.
