Narrative

DURING DSCNT OUT OF FL180; AND AT IDLE THRUST AND 315 KIAS; WE RECEIVED AN AMBER EICAS MESSAGE 'SPOILER FAIL.' AS MY FO WAS REACHING FOR THE FLT MANUAL. I LEVELED OFF THE ACFT AT 11000 FT AND THE EICAS MESSAGE SELF-CANCELED. WHEN I REINITIATED ANOTHER DSCNT OUT OF 11000 FT TO 7000 FT; THE MESSAGE REPRESENTED ITSELF. I HAD FO RUN THE ABNORMAL CHKLIST FOR 'SPOILER FAIL' WHILE I COORD WITH ATC TO DELAY OUR APCH UNTIL ALL OUR CHKLISTS; BOTH ABNORMAL AND NORMAL WERE COMPLETE. I ALSO NOTIFIED THEM OF A POSSIBLE SPOILER PROB AND ASKED FOR NO LAND AND HOLD SHORT ON RWY XXR LIKE WE HAD INITIALLY BEEN ASSIGNED. THE CTLR REASSIGNED US RWY XYL AND ASKED US TO JUST NOTIFY HIM WHEN WE WERE READY TO PROCEED WITH THE APCH. MY FO COMPLIED COMPLETELY WITH THE CHKLIST; WHICH REFERRED HIM TO THE 'INADVERTENT SPOILER OPENING INFLT' CHKLIST; WHICH HAD HIM SECURE SEVERAL CIRCUIT BREAKERS ASSOCIATED WITH THE FLT AND GND SPOILERS; AND THE CHKLIST ALSO INSTRUCTED US TO LAND AT FLAPS 22 DEGS AND ADD A MALFUNCTION INCREMENT TO FLAPS 45 SPDS; WHICH WE DID. SINCE I HAD NOT EXPERIENCED ANY UNTOWARD ROLLING OR PITCH EXCURSIONS DURING THIS EPISODE; I DID NOT CONSIDER THIS AN EMER AND DID NOT ASK FOR EQUIP TO MEET US; AS WE HAD NO ABNORMAL FLYING QUALITIES EXHIBITED OTHER THAN THE PRESENTATION OF THE EICAS MESSAGE. AS A MATTER OF HINDSIGHT; THOUGH; MY FO DID NOT MENTION TO ME THAT THE ABNORMAL CHKLIST OF 'SPOILER FAIL' SENT HIM TO AN EMER CHKLIST OF 'INADVERTENT SPOILER OPENING INFLT;' AND HAD I BEEN MADE AWARE OF THIS HIGHER PRIORITY ASSIGNED TO THIS PROB; I WOULD HAVE REQUESTED EMER EQUIP AS A PRECAUTION; DESPITE MY LACK OF UNTOWARD FLT CHARACTERISTICS UP TO THAT POINT. WE LANDED WITHOUT FURTHER INCIDENT ON RWY XYL AND WE WROTE THE DISCREPANCY UP IN THE LOG AFTER NOTIFYING BOTH OPS AND MAINT.
