Narrative:
#2 engine oil filter bypass caution light illuminated (JT8D- 15). Captain commanded the situation by calling for checklist procedures. They called for retarding the throttle to idle and if light does not extinguish, to accomplish an in-flight engine shutdown (abnormal operations checklist procedure). The light did not extinguish and we did the shutdown procedure noting that all other engine indications were normal prior to shutdown. It was determined that bwi was the nearest suitable airport considering normal descent ratios, wind, length of runway, terrain for go around and obstacles. Aircraft was landed at bwi uneventfully after accomplishing all single engine preliminary and final landing emergency checklists, briefing flight attendants and passenger and coordinating with appropriate agencies including ATC center by advising of engine shutdown and declaring the emergency.

Title: FLC OF AN MLG SHUT DOWN AN ENG DURING CRUISE DUE TO AN OIL FILTER BY PASS CAUTION LIGHT ILLUMINATION.
Narrative: #2 ENG OIL FILTER BYPASS CAUTION LIGHT ILLUMINATED (JT8D- 15). CAPT COMMANDED THE SIT BY CALLING FOR CHKLIST PROCS. THEY CALLED FOR RETARDING THE THROTTLE TO IDLE AND IF LIGHT DOES NOT EXTINGUISH, TO ACCOMPLISH AN INFLT ENG SHUTDOWN (ABNORMAL OPS CHKLIST PROC). THE LIGHT DID NOT EXTINGUISH AND WE DID THE SHUTDOWN PROC NOTING THAT ALL OTHER ENG INDICATIONS WERE NORMAL PRIOR TO SHUTDOWN. IT WAS DETERMINED THAT BWI WAS THE NEAREST SUITABLE ARPT CONSIDERING NORMAL DSCNT RATIOS, WIND, LENGTH OF RWY, TERRAIN FOR GAR AND OBSTACLES. ACFT WAS LANDED AT BWI UNEVENTFULLY AFTER ACCOMPLISHING ALL SINGLE ENG PRELIMINARY AND FINAL LNDG EMER CHKLISTS, BRIEFING FLT ATTENDANTS AND PAX AND COORDINATING WITH APPROPRIATE AGENCIES INCLUDING ATC CTR BY ADVISING OF ENG SHUTDOWN AND DECLARING THE EMER.
