Narrative:

Approaching grand rapids, level at 6000 ft, we were alerted by a 2 chime warning and MFDU alert message 'system #1 hydraulic pressure low,' followed by another 2 chime and alert message, 'system #1 hydraulic quantity low.' we confirmed this alert on overhead readout panel. We descended to 3000 ft. Once level, we were alerted with 2 chime warning and MFDU alert message, 'system #2 hydraulic pressure low.' looked to overhead, and pressure and quantity on system #2 was normal. Within 15-20 seconds, system #2 corrected and alert message cleared. I continued to fly on vectors. The captain followed procedures on MFDU's and started checklists in QRH. The captain informed flight attendants and approach control of problem. Notified dispatch and decision was made to land grand rapids. We declared emergency and requested emergency equipment. After all checklists were complete and flight attendants and cabin prepared, we landed and stopped without incident and were towed to gate. Throughout this situation all parties were kept informed and good CRM was applied between all crew members. Concerns and considerations were of winds, runways length and width, surface condition, emergency capabilities, and fuel on board for diverting. For this emergency, things were pretty smooth -- stay calm, take your time, communicate and be thorough. Supplemental information from acn 460496: broken fitting on engine #1, system #1, hydraulic pump. No corrective action possible, followed electronic checklist, with QRH follow-up: hydraulic system #1 fail procedure. I told approach we had a problem, needed to run some checklists, and requested delaying vectors. The first officer was flying and continued to fly until alternate flap and gear extension. First officer also took over most ATC communication. I contacted dispatch, checking to see if grr was the best place to land, considering runway length, width, WX, emergency equipment. Advised tower we were be disabled after landing. I asked the first officer if we had forgotten anything or was there anything we could do better. We took enough time to complete everything, but didn't waste time. Overall, this emergency went very smoothly, it was my first.

Narrative: APCHING GRAND RAPIDS, LEVEL AT 6000 FT, WE WERE ALERTED BY A 2 CHIME WARNING AND MFDU ALERT MESSAGE 'SYS #1 HYD PRESSURE LOW,' FOLLOWED BY ANOTHER 2 CHIME AND ALERT MESSAGE, 'SYS #1 HYD QUANTITY LOW.' WE CONFIRMED THIS ALERT ON OVERHEAD READOUT PANEL. WE DSNDED TO 3000 FT. ONCE LEVEL, WE WERE ALERTED WITH 2 CHIME WARNING AND MFDU ALERT MESSAGE, 'SYS #2 HYD PRESSURE LOW.' LOOKED TO OVERHEAD, AND PRESSURE AND QUANTITY ON SYS #2 WAS NORMAL. WITHIN 15-20 SECONDS, SYS #2 CORRECTED AND ALERT MESSAGE CLRED. I CONTINUED TO FLY ON VECTORS. THE CAPT FOLLOWED PROCS ON MFDU'S AND STARTED CHKLISTS IN QRH. THE CAPT INFORMED FLT ATTENDANTS AND APCH CTL OF PROB. NOTIFIED DISPATCH AND DECISION WAS MADE TO LAND GRAND RAPIDS. WE DECLARED EMER AND REQUESTED EMER EQUIP. AFTER ALL CHKLISTS WERE COMPLETE AND FLT ATTENDANTS AND CABIN PREPARED, WE LANDED AND STOPPED WITHOUT INCIDENT AND WERE TOWED TO GATE. THROUGHOUT THIS SIT ALL PARTIES WERE KEPT INFORMED AND GOOD CRM WAS APPLIED BTWN ALL CREW MEMBERS.
