Narrative:

Departed lax with B767 center air demand hydraulic pump deferred (after a 35 min maintenance delay involving various cockpit lights, door 2R slide pressure problem, and potable water problems). In spite of deferred notice stating gear retraction takes awhile without center air demand pump, it took so much longer than expected, plus gear doors were not closing, and noise and vibration stronger than expected that it became quite distracting. At 800 ft, I lowered the nose to raise flaps from 5 degrees to 1 degree, which further delayed the doors, so I maintained 200 KTS and flaps 1 degree to not further delay the gear doors. This caused the aircraft to climb faster than normal. Passing 1500 ft, I thought I'd better start leveling off. Somewhere in there, the first officer asked if we should recycle the gear which an earlier crew had done. I looked at the gear door light and said no, thinking the whole operation would take even longer. When I looked back, we were going through 2000 ft. I pulled power to idle and pushed over, but we still went through 2300 ft before I could stop it and return to 2000 ft without giving the passenger 3 or 4 negative G's. At the same time, the first officer was having trouble with a stuck microphone on the frequency, so we changed to departure control and were turning from 250 degree heading to 235 degree heading on the loop 1 SID. Departure control told us to climb to 13000 ft, saying nothing about our short altitude excursion. Crew members need to be reminded to fly the airplane first, especially altitudes and headings, and leave non emergency system problems to the PNF until everything is stabilized and time permits, then get back, cautiously, into the system loop.

Title: B767-200 DEPARTING WITH DEFERRED CTR DEMAND HYD PUMP, RESULTED IN VERY SLOW GEAR RETRACTION. WITH ALT RESTR AND SPD RESTR DUE TO GEAR AND FLAP SPDS, ACFT CLBED ABOVE ASSIGNED ALT. RPTR CAPT BELIEVES THAT THE HYD PUMP SHOULD NOT BE DEFERRED AS A SAFETY OF FLT ITEM.

Narrative: DEPARTED LAX WITH B767 CTR AIR DEMAND HYD PUMP DEFERRED (AFTER A 35 MIN MAINT DELAY INVOLVING VARIOUS COCKPIT LIGHTS, DOOR 2R SLIDE PRESSURE PROB, AND POTABLE WATER PROBS). IN SPITE OF DEFERRED NOTICE STATING GEAR RETRACTION TAKES AWHILE WITHOUT CTR AIR DEMAND PUMP, IT TOOK SO MUCH LONGER THAN EXPECTED, PLUS GEAR DOORS WERE NOT CLOSING, AND NOISE AND VIBRATION STRONGER THAN EXPECTED THAT IT BECAME QUITE DISTRACTING. AT 800 FT, I LOWERED THE NOSE TO RAISE FLAPS FROM 5 DEGS TO 1 DEG, WHICH FURTHER DELAYED THE DOORS, SO I MAINTAINED 200 KTS AND FLAPS 1 DEG TO NOT FURTHER DELAY THE GEAR DOORS. THIS CAUSED THE ACFT TO CLB FASTER THAN NORMAL. PASSING 1500 FT, I THOUGHT I'D BETTER START LEVELING OFF. SOMEWHERE IN THERE, THE FO ASKED IF WE SHOULD RECYCLE THE GEAR WHICH AN EARLIER CREW HAD DONE. I LOOKED AT THE GEAR DOOR LIGHT AND SAID NO, THINKING THE WHOLE OP WOULD TAKE EVEN LONGER. WHEN I LOOKED BACK, WE WERE GOING THROUGH 2000 FT. I PULLED PWR TO IDLE AND PUSHED OVER, BUT WE STILL WENT THROUGH 2300 FT BEFORE I COULD STOP IT AND RETURN TO 2000 FT WITHOUT GIVING THE PAX 3 OR 4 NEGATIVE G'S. AT THE SAME TIME, THE FO WAS HAVING TROUBLE WITH A STUCK MIKE ON THE FREQ, SO WE CHANGED TO DEP CTL AND WERE TURNING FROM 250 DEG HDG TO 235 DEG HDG ON THE LOOP 1 SID. DEP CTL TOLD US TO CLB TO 13000 FT, SAYING NOTHING ABOUT OUR SHORT ALT EXCURSION. CREW MEMBERS NEED TO BE REMINDED TO FLY THE AIRPLANE FIRST, ESPECIALLY ALTS AND HDGS, AND LEAVE NON EMER SYS PROBS TO THE PNF UNTIL EVERYTHING IS STABILIZED AND TIME PERMITS, THEN GET BACK, CAUTIOUSLY, INTO THE SYS LOOP.
