Narrative:

During climb out, we discussed (other aft flight attendant) having difficulty clearing our ears. At approximately XA10 we began a deep descent. I contacted the purser to ask what was happening. Just then, she received an emergency chime to come to the cockpit. She contacted me and said we were making an emergency landing in mia due to pressurization problems with the aircraft. During descent, we experienced a gradual decompression, and upon landing, a spontaneous decompression. During the spontaneous decompression the aircraft filled with condensation, followed by a rapid drop in cabin temperature. A number of crew members experienced pain and dizziness during the spontaneous decompression. All 8 flight attendants were taken to air carrier's medical, and 3 were removed from flight duty -- including myself. The 3 of us experienced trauma to our ears. Callback conversation with reporter revealed the following information: the reporter stated that he thought that they were at 14000 ft when the captain made the decision to descend. Evidently, the cabin pressure was stuck at 9000 ft. The captain told the people and cabin crew that when the outside altitude equaled the inside altitude, they would have some ear discomfort. The oxygen masks never deployed. When they landed, there was a loud rush of air, as if something was wrong with the ventilation. The crew did not prepare the plane for an evacuate/evacuation. The plane was taken OTS, and the passenger put on another plane several hours later.

Title: CABIN ATTENDANT RPT, A300-600R MIA-BOS, ON CLBOUT, PRESSURIZATION PROBS. EMER DSCNT. RETURN TO MIA. FLT CANCELLED.

Narrative: DURING CLBOUT, WE DISCUSSED (OTHER AFT FLT ATTENDANT) HAVING DIFFICULTY CLRING OUR EARS. AT APPROX XA10 WE BEGAN A DEEP DSCNT. I CONTACTED THE PURSER TO ASK WHAT WAS HAPPENING. JUST THEN, SHE RECEIVED AN EMER CHIME TO COME TO THE COCKPIT. SHE CONTACTED ME AND SAID WE WERE MAKING AN EMER LNDG IN MIA DUE TO PRESSURIZATION PROBS WITH THE ACFT. DURING DSCNT, WE EXPERIENCED A GRADUAL DECOMPRESSION, AND UPON LNDG, A SPONTANEOUS DECOMPRESSION. DURING THE SPONTANEOUS DECOMPRESSION THE ACFT FILLED WITH CONDENSATION, FOLLOWED BY A RAPID DROP IN CABIN TEMP. A NUMBER OF CREW MEMBERS EXPERIENCED PAIN AND DIZZINESS DURING THE SPONTANEOUS DECOMPRESSION. ALL 8 FLT ATTENDANTS WERE TAKEN TO ACR'S MEDICAL, AND 3 WERE REMOVED FROM FLT DUTY -- INCLUDING MYSELF. THE 3 OF US EXPERIENCED TRAUMA TO OUR EARS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT HE THOUGHT THAT THEY WERE AT 14000 FT WHEN THE CAPT MADE THE DECISION TO DSND. EVIDENTLY, THE CABIN PRESSURE WAS STUCK AT 9000 FT. THE CAPT TOLD THE PEOPLE AND CABIN CREW THAT WHEN THE OUTSIDE ALT EQUALED THE INSIDE ALT, THEY WOULD HAVE SOME EAR DISCOMFORT. THE OXYGEN MASKS NEVER DEPLOYED. WHEN THEY LANDED, THERE WAS A LOUD RUSH OF AIR, AS IF SOMETHING WAS WRONG WITH THE VENTILATION. THE CREW DID NOT PREPARE THE PLANE FOR AN EVAC.
