Narrative:

After takeoff and after flap retraction, we got indications of dual 2-CHANNEL failure of elevator feel system and flap overspd protection system. Climbed out of 10000 ft (assuring terrain clearance, still IMC) and instructed first officer and so to execute irregular procedures for problem. Aircraft heavy in pitch control due to elevation ft problem. Crew unable to correct problems. Still IMC, at 19000 ft MSL got cabin altitude warning. Cabin altitude 9000 ft. Instructed so to descend cabin. He was unable. Got clearance to lower altitude, directed donning of oxygen masks and began expedited descent. Passenger oxygen masks deployed. In descent, so told me he found problem and had cabin under control. He found packs and bleeds off! Returned to pdx and made uneventful overweight landing. Crew was diverted from SOP (pack and bleeds on, as per after takeoff checklist) by dual irregularity (still unexplained). All other fleets in this company takeoff with packs and bleeds on. For reasons unknown to me, the widebody transport takes off with packs and bleeds off, a certain trap. I suggest taking off with packs on unless performance requires a no-pack takeoff and this is under consideration at the present time. Supplemental information from acn 229799: the antenna anti-ice disagree light also illuminated on the pilot's overhead caution panel. This required another irregular checklist procedure to be accomplished. The cabin altitude warning horn sounded (cabin altitude about 9500 ft). Aircraft altitude between 17000-18000 ft with the cabin altitude rapidly increasing. Immediate attempts were made to lower the cabin altitude in the standby and manual modes, no luck. Cabin altitude has now climbed to 14000 ft and aircraft altitude about 19000 ft. The cabin oxygen masks were automatically deployed when cabin altitude reached 14000 ft. The so went through the emergency descent steps after donning the oxygen mask that he realized the engine bleeds and air conditioning packs were off. The crew's cockpit leadership resources were very positive throughout these irregular happenings. The flight attendants and passenger were also very good during this period. No injuries or major complaints occurred from the passenger. The so and crew became involved with multiple irregular procedures during the takeoff climb which diverted the so from accomplishing the normal after takeoff checklist, which would have turned bleeds and packs on to pressurize the cabin normally.

Title: AN ACR WDB CREW SUFFERED 2 ABNORMAL SITS RIGHT AFTER TKOF INTO WX IN MOUNTAINOUS TERRAIN. THE SO FAILED TO PRESSURIZE THE ACFT IN ADDITION TO THE CTL PROBS.

Narrative: AFTER TKOF AND AFTER FLAP RETRACTION, WE GOT INDICATIONS OF DUAL 2-CHANNEL FAILURE OF ELEVATOR FEEL SYS AND FLAP OVERSPD PROTECTION SYS. CLBED OUT OF 10000 FT (ASSURING TERRAIN CLRNC, STILL IMC) AND INSTRUCTED FO AND SO TO EXECUTE IRREGULAR PROCS FOR PROB. ACFT HVY IN PITCH CTL DUE TO ELEVATION FT PROB. CREW UNABLE TO CORRECT PROBS. STILL IMC, AT 19000 FT MSL GOT CABIN ALT WARNING. CABIN ALT 9000 FT. INSTRUCTED SO TO DSND CABIN. HE WAS UNABLE. GOT CLRNC TO LOWER ALT, DIRECTED DONNING OF OXYGEN MASKS AND BEGAN EXPEDITED DSCNT. PAX OXYGEN MASKS DEPLOYED. IN DSCNT, SO TOLD ME HE FOUND PROB AND HAD CABIN UNDER CTL. HE FOUND PACKS AND BLEEDS OFF! RETURNED TO PDX AND MADE UNEVENTFUL OVERWT LNDG. CREW WAS DIVERTED FROM SOP (PACK AND BLEEDS ON, AS PER AFTER TKOF CHKLIST) BY DUAL IRREGULARITY (STILL UNEXPLAINED). ALL OTHER FLEETS IN THIS COMPANY TKOF WITH PACKS AND BLEEDS ON. FOR REASONS UNKNOWN TO ME, THE WDB TAKES OFF WITH PACKS AND BLEEDS OFF, A CERTAIN TRAP. I SUGGEST TAKING OFF WITH PACKS ON UNLESS PERFORMANCE REQUIRES A NO-PACK TKOF AND THIS IS UNDER CONSIDERATION AT THE PRESENT TIME. SUPPLEMENTAL INFO FROM ACN 229799: THE ANTENNA ANTI-ICE DISAGREE LIGHT ALSO ILLUMINATED ON THE PLT'S OVERHEAD CAUTION PANEL. THIS REQUIRED ANOTHER IRREGULAR CHKLIST PROC TO BE ACCOMPLISHED. THE CABIN ALT WARNING HORN SOUNDED (CABIN ALT ABOUT 9500 FT). ACFT ALT BTWN 17000-18000 FT WITH THE CABIN ALT RAPIDLY INCREASING. IMMEDIATE ATTEMPTS WERE MADE TO LOWER THE CABIN ALT IN THE STANDBY AND MANUAL MODES, NO LUCK. CABIN ALT HAS NOW CLBED TO 14000 FT AND ACFT ALT ABOUT 19000 FT. THE CABIN OXYGEN MASKS WERE AUTOMATICALLY DEPLOYED WHEN CABIN ALT REACHED 14000 FT. THE SO WENT THROUGH THE EMER DSCNT STEPS AFTER DONNING THE OXYGEN MASK THAT HE REALIZED THE ENG BLEEDS AND AIR CONDITIONING PACKS WERE OFF. THE CREW'S COCKPIT LEADERSHIP RESOURCES WERE VERY POSITIVE THROUGHOUT THESE IRREGULAR HAPPENINGS. THE FLT ATTENDANTS AND PAX WERE ALSO VERY GOOD DURING THIS PERIOD. NO INJURIES OR MAJOR COMPLAINTS OCCURRED FROM THE PAX. THE SO AND CREW BECAME INVOLVED WITH MULTIPLE IRREGULAR PROCS DURING THE TKOF CLB WHICH DIVERTED THE SO FROM ACCOMPLISHING THE NORMAL AFTER TKOF CHKLIST, WHICH WOULD HAVE TURNED BLEEDS AND PACKS ON TO PRESSURIZE THE CABIN NORMALLY.
