Narrative:

During preflight I inadvertently missed a spoiler valve position. It normally is in the vertical or spoileron position. It had been in maintenance and was released for service in the wrong position. The flight deck indicator was inoperable and was on MEL. If this is in the off position or bypass, the inbound spoilers will not deploy on landing. During taxi since the outboard spoilers functioned the control check offered no indication of system bypass. No incident or event occurred and landing in cle was uneventful. This would however effect landing distance and landing calculation. We landed on a 10000 ft runway and thus the point is moot. However it is my responsibility to perform a thorough preflight and catch such an item.

Title: A DC9 FO FAILS TO NOTICE THE SPOILER VALVE POS ON PREFLT RESULTING IN THE FLT BEING DISPATCHED IN NON COMPLIANCE WITH THE MEL.

Narrative: DURING PREFLT I INADVERTENTLY MISSED A SPOILER VALVE POS. IT NORMALLY IS IN THE VERT OR SPOILERON POS. IT HAD BEEN IN MAINT AND WAS RELEASED FOR SVC IN THE WRONG POS. THE FLT DECK INDICATOR WAS INOPERABLE AND WAS ON MEL. IF THIS IS IN THE OFF POS OR BYPASS, THE INBOUND SPOILERS WILL NOT DEPLOY ON LNDG. DURING TAXI SINCE THE OUTBOARD SPOILERS FUNCTIONED THE CTL CHK OFFERED NO INDICATION OF SYS BYPASS. NO INCIDENT OR EVENT OCCURRED AND LNDG IN CLE WAS UNEVENTFUL. THIS WOULD HOWEVER EFFECT LNDG DISTANCE AND LNDG CALCULATION. WE LANDED ON A 10000 FT RWY AND THUS THE POINT IS MOOT. HOWEVER IT IS MY RESPONSIBILITY TO PERFORM A THOROUGH PREFLT AND CATCH SUCH AN ITEM.
