Narrative:

Flight departed paris on time and what seemed under normal conditions. During climb to cruise it became apparent to us, by our inability to clear our ears effectively, that there was a problem regulating the pressurization of the aircraft. Shortly after, the captain notified us that they had relatively little or no control stabilizing the cabin pressure and that we would be diverting to land. Appropriate actions were taken by the cabin crew to secure the cabin and passenger for landing as the captain made an informative PA to notify the customers of the maintenance problem. He concisely told them we would land shortly in lhr to have the mechanics check and fix our pressurization system. He also reassured them of the normality of fire equipment on the field due to our weight and the heat on the tires and brakes. In my opinion this was extremely helpful to the cabin crew and comforting to the passenger to not be left in the dark. It was just enough accurate information. We landed without incident, were checked over by the fire department and taxied to the maintenance area. The problem was corrected and we left for new york. (Due to the fact that the crew went illegal for the extended duty day.) the cockpit and cabin crews worked extremely well due to good open lines of communication. Also, the lhr ground personnel could not have been more helpful or well prepared. The best of a bad situation.

Title: FLT ATTENDANT RPT REGARDING A PRESSURIZATION PROB ON A B767-300 WHICH DIVERTED FOR MAINT AND THEN CONTINUED ON THE OCEANIC FLT.

Narrative: FLT DEPARTED PARIS ON TIME AND WHAT SEEMED UNDER NORMAL CONDITIONS. DURING CLB TO CRUISE IT BECAME APPARENT TO US, BY OUR INABILITY TO CLR OUR EARS EFFECTIVELY, THAT THERE WAS A PROB REGULATING THE PRESSURIZATION OF THE ACFT. SHORTLY AFTER, THE CAPT NOTIFIED US THAT THEY HAD RELATIVELY LITTLE OR NO CTL STABILIZING THE CABIN PRESSURE AND THAT WE WOULD BE DIVERTING TO LAND. APPROPRIATE ACTIONS WERE TAKEN BY THE CABIN CREW TO SECURE THE CABIN AND PAX FOR LNDG AS THE CAPT MADE AN INFORMATIVE PA TO NOTIFY THE CUSTOMERS OF THE MAINT PROB. HE CONCISELY TOLD THEM WE WOULD LAND SHORTLY IN LHR TO HAVE THE MECHS CHK AND FIX OUR PRESSURIZATION SYS. HE ALSO REASSURED THEM OF THE NORMALITY OF FIRE EQUIP ON THE FIELD DUE TO OUR WT AND THE HEAT ON THE TIRES AND BRAKES. IN MY OPINION THIS WAS EXTREMELY HELPFUL TO THE CABIN CREW AND COMFORTING TO THE PAX TO NOT BE LEFT IN THE DARK. IT WAS JUST ENOUGH ACCURATE INFO. WE LANDED WITHOUT INCIDENT, WERE CHKED OVER BY THE FIRE DEPT AND TAXIED TO THE MAINT AREA. THE PROB WAS CORRECTED AND WE LEFT FOR NEW YORK. (DUE TO THE FACT THAT THE CREW WENT ILLEGAL FOR THE EXTENDED DUTY DAY.) THE COCKPIT AND CABIN CREWS WORKED EXTREMELY WELL DUE TO GOOD OPEN LINES OF COM. ALSO, THE LHR GND PERSONNEL COULD NOT HAVE BEEN MORE HELPFUL OR WELL PREPARED. THE BEST OF A BAD SIT.
