Narrative:

After takeoff we were unable to raise landing gear. Aircraft would not pressurize. Upon switching to departure I notified departure control and told them we would return to oma. Followed procedure in aircraft flight manual, determined aircraft in ground mode (nose wheel steerable), operated pressurization in manual mode, did not retract gear per procedure. During vector for return, I notified company operations personnel in oma of problem and of our return. While on vector for return oma station personnel called back via radio with message from maintenance control with suggestions on trying to retract gear. I responded that we had followed procedure in manual and was not to retract gear. They relayed to maintenance control then relayed suggestions from maintenance control again. It was obvious oma station personnel did not know medium large transport system technicalities and relaying information to maintenance control through them would be useless. I informed them we had followed procedure, would be returning and would discuss it once we got on ground. I still had many duties to perform for landing back at oma and did not want this distraction to affect safety of flight. Landing was normal. After landing, parking and shutdown paperwork was accomplished and we were informed to go to hotel as maintenance personnel would be flown in and work on aircraft. Before leaving airport for hotel, FAA had called (flight standards, not tower) wanting information. According to local airline company personnel the local office monitors tower/radar frequency. Captain wrote log book entry 'unable to raise landing gear after takeoff. Nose gear steerable, aircraft would not pressurize.' upon return to aircraft after maintenance personnel had approved aircraft for return to service. The corrective action log entry was 'found nose strut low, svced nose strut with fluid and nitrogen per maintenance manual chapter 12, and swung nose gear. All indications checked normal. Returned aircraft to normal. Jack and jack pads removed.' I performed the preflight exterior inspection and nose gear strut extension was normal. Captain inspected nose gear area after return to oma and found it normal. The way the log entry is worded it seems to place the blame on flight crew. We were told by station personnel that maintenance could find no problems. I believe this is a case where maintenance must enter something in log so they wrote this even though I do not believe the nose strut was low.

Title: MLG ON TKOF HAS GEAR THAT WILL NOT RETRACT AND UNABLE TO PRESSURIZE. RETURN LAND.

Narrative: AFTER TKOF WE WERE UNABLE TO RAISE LNDG GEAR. ACFT WOULD NOT PRESSURIZE. UPON SWITCHING TO DEP I NOTIFIED DEP CTL AND TOLD THEM WE WOULD RETURN TO OMA. FOLLOWED PROC IN ACFT FLT MANUAL, DETERMINED ACFT IN GND MODE (NOSE WHEEL STEERABLE), OPERATED PRESSURIZATION IN MANUAL MODE, DID NOT RETRACT GEAR PER PROC. DURING VECTOR FOR RETURN, I NOTIFIED COMPANY OPS PERSONNEL IN OMA OF PROB AND OF OUR RETURN. WHILE ON VECTOR FOR RETURN OMA STATION PERSONNEL CALLED BACK VIA RADIO WITH MESSAGE FROM MAINT CTL WITH SUGGESTIONS ON TRYING TO RETRACT GEAR. I RESPONDED THAT WE HAD FOLLOWED PROC IN MANUAL AND WAS NOT TO RETRACT GEAR. THEY RELAYED TO MAINT CTL THEN RELAYED SUGGESTIONS FROM MAINT CTL AGAIN. IT WAS OBVIOUS OMA STATION PERSONNEL DID NOT KNOW MLG SYS TECHNICALITIES AND RELAYING INFO TO MAINT CTL THROUGH THEM WOULD BE USELESS. I INFORMED THEM WE HAD FOLLOWED PROC, WOULD BE RETURNING AND WOULD DISCUSS IT ONCE WE GOT ON GND. I STILL HAD MANY DUTIES TO PERFORM FOR LNDG BACK AT OMA AND DID NOT WANT THIS DISTR TO AFFECT SAFETY OF FLT. LNDG WAS NORMAL. AFTER LNDG, PARKING AND SHUTDOWN PAPERWORK WAS ACCOMPLISHED AND WE WERE INFORMED TO GO TO HOTEL AS MAINT PERSONNEL WOULD BE FLOWN IN AND WORK ON ACFT. BEFORE LEAVING ARPT FOR HOTEL, FAA HAD CALLED (FLT STANDARDS, NOT TWR) WANTING INFO. ACCORDING TO LCL AIRLINE COMPANY PERSONNEL THE LCL OFFICE MONITORS TWR/RADAR FREQ. CAPT WROTE LOG BOOK ENTRY 'UNABLE TO RAISE LNDG GEAR AFTER TKOF. NOSE GEAR STEERABLE, ACFT WOULD NOT PRESSURIZE.' UPON RETURN TO ACFT AFTER MAINT PERSONNEL HAD APPROVED ACFT FOR RETURN TO SVC. THE CORRECTIVE ACTION LOG ENTRY WAS 'FOUND NOSE STRUT LOW, SVCED NOSE STRUT WITH FLUID AND NITROGEN PER MAINT MANUAL CHAPTER 12, AND SWUNG NOSE GEAR. ALL INDICATIONS CHKED NORMAL. RETURNED ACFT TO NORMAL. JACK AND JACK PADS REMOVED.' I PERFORMED THE PREFLT EXTERIOR INSPECTION AND NOSE GEAR STRUT EXTENSION WAS NORMAL. CAPT INSPECTED NOSE GEAR AREA AFTER RETURN TO OMA AND FOUND IT NORMAL. THE WAY THE LOG ENTRY IS WORDED IT SEEMS TO PLACE THE BLAME ON FLC. WE WERE TOLD BY STATION PERSONNEL THAT MAINT COULD FIND NO PROBS. I BELIEVE THIS IS A CASE WHERE MAINT MUST ENTER SOMETHING IN LOG SO THEY WROTE THIS EVEN THOUGH I DO NOT BELIEVE THE NOSE STRUT WAS LOW.
