Narrative:

Task saturation. Self induced. While on minks 1 arrival into lga with numerous vectors and small stepdowns for spacing on STAR, actual profile descent was initiated at FL260. As descent was started, senior flight attendant entered cockpit with cabin maintenance write-ups. Captain's leg (segment) pbi-lga with first officer primary duties ATC (radios) as I (captain) was flying the aircraft I had the first officer write the cabin discrepancies in the maintenance log and advise company of logbook write-ups as he was on company radio frequency, I would fly aircraft and monitor primary radio (ATC). As we descended through FL180 qnh was set, seat belt sign was illuminated. (As we used the ACARS system to print lga ATIS approach in use was already known, briefed and speed/altitude bugs were set.) cabin crew prepared cabin for final approach into lga. As we leveled off at 11000 ft, first officer just finished briefing lga operations of maintenance action requirements, gate information, etc, and took over primary radio duties. As FL180 is normal phase of flight for descent/approach checklist and as we were already at 11000 ft with all bugs set, the descent checklist was overlooked (missed). The most important item on that checklist is the hydraulic pumps -- high and on. Without this action, as aircraft is configured for landing, nose gear would not extend to the down and locked position. Landing had to be aborted. Switch position was realized, appropriate checklists were run and flight landed safely.

Title: UNKNOWN ACFT CREW DID NOT HAVE ACFT PROPERLY CONFIGURED HYDRAULICALLY FOR LNDG,

Narrative: TASK SATURATION. SELF INDUCED. WHILE ON MINKS 1 ARR INTO LGA WITH NUMEROUS VECTORS AND SMALL STEPDOWNS FOR SPACING ON STAR, ACTUAL PROFILE DSCNT WAS INITIATED AT FL260. AS DSCNT WAS STARTED, SENIOR FLT ATTENDANT ENTERED COCKPIT WITH CABIN MAINT WRITE-UPS. CAPT'S LEG (SEGMENT) PBI-LGA WITH FO PRIMARY DUTIES ATC (RADIOS) AS I (CAPT) WAS FLYING THE ACFT I HAD THE FO WRITE THE CABIN DISCREPANCIES IN THE MAINT LOG AND ADVISE COMPANY OF LOGBOOK WRITE-UPS AS HE WAS ON COMPANY RADIO FREQ, I WOULD FLY ACFT AND MONITOR PRIMARY RADIO (ATC). AS WE DSNDED THROUGH FL180 QNH WAS SET, SEAT BELT SIGN WAS ILLUMINATED. (AS WE USED THE ACARS SYS TO PRINT LGA ATIS APCH IN USE WAS ALREADY KNOWN, BRIEFED AND SPD/ALT BUGS WERE SET.) CABIN CREW PREPARED CABIN FOR FINAL APCH INTO LGA. AS WE LEVELED OFF AT 11000 FT, FO JUST FINISHED BRIEFING LGA OPS OF MAINT ACTION REQUIREMENTS, GATE INFO, ETC, AND TOOK OVER PRIMARY RADIO DUTIES. AS FL180 IS NORMAL PHASE OF FLT FOR DSCNT/APCH CHKLIST AND AS WE WERE ALREADY AT 11000 FT WITH ALL BUGS SET, THE DSCNT CHKLIST WAS OVERLOOKED (MISSED). THE MOST IMPORTANT ITEM ON THAT CHKLIST IS THE HYD PUMPS -- HIGH AND ON. WITHOUT THIS ACTION, AS ACFT IS CONFIGURED FOR LNDG, NOSE GEAR WOULD NOT EXTEND TO THE DOWN AND LOCKED POS. LNDG HAD TO BE ABORTED. SWITCH POS WAS REALIZED, APPROPRIATE CHKLISTS WERE RUN AND FLT LANDED SAFELY.
