Narrative

ON DSCNT WITH ZZZ APCH CTL; 'SPOILERONS FAULT' CAUTION MESSAGE CAME ON. SECONDS LATER 'SPOILERS FAULT' MESSAGE ALSO CAME ON. PROCEEDED TO RUN QRH PROCS. FIRST; FOR 'SPOILERONS FAULT' THEN SPOILERS FAULT. MOST RESTRICTIVE PROC LIMITED TO FLAPS SELECTION 20 DEGS MAX. WE THEN ADVISED ATC WE WOULD NEED TO DELAY APCH TO WORK ON PROB. WE WERE GIVEN BOX PATTERN VECTORS. FO WAS HANDLING ATC AND FLYING ACFT. CAPT WAS CONTACTING DISPATCH AND MAINT CTL FOR INPUT. DISPATCH QUICKLY GAVE US OUR RWY LENGTH REQUIRED BASED ON ACFT WT AND THRUST REVERSERS OPERABLE. MAINT CTL HAD NO OTHER HELP THAN THE QRH PROCS. HOWEVER MAINT CTL INFORMED CAPT THAT THE ACFT HAD THE SAME PROB A COUPLE OF DAYS PRIOR. AFTER SPEAKING WITH DISPATCH AND VERIFYING A SAFE LNDG COULD BE MADE WE INFORMED DISPATCH AND ATC WE WERE DECLARING AN EMER AS A PRECAUTION. FLT ATTENDANT WAS THEN INFORMED AS TO THE PROB AND ASKED TO PREPARE FOR AN EMER LNDG AND TO PLACE PAX IN BRACE POS. CAPT THEN MADE A PA TO INFORM PAX OF THE PROB. AFTER FLT ATTENDANT INFORMED CREW THE CABIN WAS READY; CREW REQUESTED AN ILS TO RWY 1. WX WAS CLR. ARPT WAS IN SIGHT ENTIRE APCH. CAPT ASSUMED CTL AND FLEW THE APCH AND LNDG WITHOUT INCIDENT. ACFT WAS TAXIED UNDER ITS OWN PWR TO GATE. PAX WERE THEN DEPLANED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED NO INFO WAS GIVEN TO THE FLT CREW ON THE MAINT ACTION TAKEN. BUT MAINT CTL WAS CORRECT IN ADVISING THESE WARNINGS WERE WRITTEN UP IN THE LOGBOOK PREVIOUSLY.
