FLC OF ACR MLG LOST CABIN PRESSURE AND RETURNED TO LAND.

Narrative

AFTER TKOF FROM SFO-SEA ON REGULAR SCHEDULED FLT; ACFT SEEMED TO STAY IN GND MODE. CAPT FLEW WHILE FO ATTEMPTED TO SOLVE PROBLEM AND CONTACT COMPANY MAINT. SLOW CLB CONTINUED AND AT ABOUT FL240 R PACK TRIPPED OFF. FO STILL WAS INVOLVED WITH MECHANICAL PROBLEMS AND AT ABOUT FL300 PLUS; L PACK TRIPPED OFF AND WE SEEMED TO LOSE CABIN PRESSURE CTL. I REQUESTED A LOWER ALT AND ZOA CLRED US TO FL240 AND ON DOWN TO 15000 FT THEN 10000 FT. WE DID MAKE A STEEP DSCNT; BUT NOT A FULL EMER DSCNT AS WE ALWAYS SEEMED TO HAVE LIMITED CABIN PRESSURE CTL. NO EMER WAS DECLARED AND HIGHEST CABIN ALT REACHED WAS ABOUT 9500 FT. WE REMAINED AT 10000 FT UNTIL OUR DSCNT FOR LNDG AT SFO. EMER EQUIP MET OUR ACFT UPON LNDG AND FAA INSPECTORS MET US UPON REACHING THE GATE. THE INSPECTORS STATED THE TWR HAD RECEIVED NOTIFICATION FROM CTR WHO HAD RECEIVED A CALL FROM THE HWY PATROL SAYING THEY HAD A CELLULAR TELEPHONE CALL FROM A PAX ON OUR FLT SAYING HE WAS ON AN ACFT OUT OF CTL AND GOING TO HIT A MOUNTAIN. AFTER BEING QUESTIONED BY THE FAA WE GOT A NEW ACFT AND FLEW A NORMAL FLT TO SEA. WE WERE ALWAYS IN FULL CTL OF OUR ACFT; THOUGH VERY BUSY AT THE TIME. I MADE AN ANNOUNCEMENT TO THE CABIN AS SOON AS I WAS ABLE AFTER THE LAST LEVEL OFF. ACFT SYS WERE NORMAL UNTIL TKOF. AFTER THAT; WE HAD PROBLEMS RAISING THE GEAR; TCASII. ATC TRANSPONDERS; AUTOTHROTTLE; PACKS; PRESSURIZATION CTL; AFTER LNDG R ANTI-SKID. COM WITH THE COMPANY VIA COMRDO WAS VERY HARD TO ESTABLISH AND NEVER USEFUL. EVIDENTLY A CELLULAR TELEPHONE USE WAS BETTER. I KNOW PAX WERE CONCERNED AND NEED TO BE TOLD WHAT IS GOING ON. I SPOKE TO THEM AS SOON AS ABLE; BUT WE HAVE NO WAY TO CTL PERSONS FROM USING ACFT CELLULAR TELEPHONES TO MAKE CALLS THAT MAY NOT REFLECT FACTUAL OR TECHNICAL INFO TO ANYONE ON THE GND. THAT MAY BE MORE OF A PROBLEM IN THE FUTURE. I ALSO LET PAX LISTEN TO OUR COMS WITH ATC ON OUR PAX ENTERTAINMENT SYS; THOUGH I KNOW SOME PLTS WILL NOT; BECAUSE PAX MAY MISUNDERSTAND SOME CALLS. WE ARE ABLE TO CTL THIS FEATURE AND MAYBE WE SHOULD HAVE A SWITCH FOR THE CELLULAR TELEPHONES AS WELL. SUPPLEMENTAL INFO FROM ACN 223899: PAX IN FIRST CLASS USED AIRPHONE TO CALL 911 CHP/MARIN COUNTY AND RPT OUT OF CTL IN DANGER OF HITTING A MOUNTAIN. SUSPECT ACFT WAS NEVER IN DANGER OF HITTING ANYTHING AND EXCEPT FOR INITIAL PUSHOVER OF NOSE; ACTUATION OF SPD BRAKE TO BEGIN DSCNT; OPS WERE MOSTLY NORMAL.
