Narrative:
First officer flying on final approach. After selecting landing gear handle down we got hydraulic system #1 quantity, pressure and failure messages. All 3 green came down ok. We went missed approach and requested radar vectors for another approach. While in the second pattern we reviewed hydraulic system #1 failure procedures as well as alternate landing gear and flap procedures. We were unable to raise the main gear doors. We informed ewr operations of our requirements (raise gear doors on runway, tow to gate). We informed ATC that we needed to stop on the runway for maintenance and we briefed the flight attendants. Captain flew the visual approach to runway 22R, flaps 25 degrees. The landing was uneventful. We shut down the engines. Maintenance raised the gear doors. We were towed to the gate where the passenger deplaned.

Title: FLC OF AN MLG ON FINAL APCH HAS HYD QUANTITY, PRESSURE AND FAILURE MESSAGES. A GAR IS PERFORMED AND RETURN FOR SECOND LNDG WITH REQUEST FOR MAINT ON RWY TO CLOSE GEAR DOORS AND TOW TO GATE.
Narrative: FO FLYING ON FINAL APCH. AFTER SELECTING LNDG GEAR HANDLE DOWN WE GOT HYD SYS #1 QUANTITY, PRESSURE AND FAILURE MESSAGES. ALL 3 GREEN CAME DOWN OK. WE WENT MISSED APCH AND REQUESTED RADAR VECTORS FOR ANOTHER APCH. WHILE IN THE SECOND PATTERN WE REVIEWED HYD SYS #1 FAILURE PROCS AS WELL AS ALTERNATE LNDG GEAR AND FLAP PROCS. WE WERE UNABLE TO RAISE THE MAIN GEAR DOORS. WE INFORMED EWR OPS OF OUR REQUIREMENTS (RAISE GEAR DOORS ON RWY, TOW TO GATE). WE INFORMED ATC THAT WE NEEDED TO STOP ON THE RWY FOR MAINT AND WE BRIEFED THE FLT ATTENDANTS. CAPT FLEW THE VISUAL APCH TO RWY 22R, FLAPS 25 DEGS. THE LNDG WAS UNEVENTFUL. WE SHUT DOWN THE ENGS. MAINT RAISED THE GEAR DOORS. WE WERE TOWED TO THE GATE WHERE THE PAX DEPLANED.
