Air carrier flight crew become distraction on final approach and forget to lower gear. GPWS continues to alarm, alerting the flight crew to the no gear situation. PIC executes go around.

Narrative:
On approach to runway 18L in cvg, intercepted GS several mi outside the FAF in VFR conditions. Field WX had been 3 mi. As we approached the OM, the field WX went to 5000 ft RVR. In attempting to adjust speed for traffic, adjust for the changing WX, etc, we failed to lower the gear or complete the landing checklist. As we broke out, the 'terrain' GPWS warning sounded, but as we had the field visually, we at first assumed a faulty GPWS. We then recognized the gear problem, executed a normal missed approach, and returned to land without incident. Contributing factors were: high workload in critical phase of approach and knowledge (cvg commercial chart pages) that GPWS warnings on approach in cvg are not uncommon, causing a slight delay in execution of missed approach.

Title: ACR FLC BECOME DISTR ON FINAL APCH AND FORGET TO LOWER GEAR. GPWS CONTINUES TO ALARM, ALERTING THE FLC TO THE NO GEAR SIT. PIC EXECUTES GAR.
Narrative: ON APCH TO RWY 18L IN CVG, INTERCEPTED GS SEVERAL MI OUTSIDE THE FAF IN VFR CONDITIONS. FIELD WX HAD BEEN 3 MI. AS WE APCHED THE OM, THE FIELD WX WENT TO 5000 FT RVR. IN ATTEMPTING TO ADJUST SPD FOR TFC, ADJUST FOR THE CHANGING WX, ETC, WE FAILED TO LOWER THE GEAR OR COMPLETE THE LNDG CHKLIST. AS WE BROKE OUT, THE 'TERRAIN' GPWS WARNING SOUNDED, BUT AS WE HAD THE FIELD VISUALLY, WE AT FIRST ASSUMED A FAULTY GPWS. WE THEN RECOGNIZED THE GEAR PROB, EXECUTED A NORMAL MISSED APCH, AND RETURNED TO LAND WITHOUT INCIDENT. CONTRIBUTING FACTORS WERE: HIGH WORKLOAD IN CRITICAL PHASE OF APCH AND KNOWLEDGE (CVG COMMERCIAL CHART PAGES) THAT GPWS WARNINGS ON APCH IN CVG ARE NOT UNCOMMON, CAUSING A SLIGHT DELAY IN EXECUTION OF MISSED APCH.
