Narrative:
Dispatched with TCASII inoperative. Day WX was VFR, unlimited visibility. Established on final, tracking the ILS on a visual approach, just outside the OM to runway 6L. Approach called traffic 12 O'clock position, type and altitude unknown. At the same moment, I acquired visually an older, dark blue cessna moving right to left, directly in front of me and somewhat lower. I slowed our descent and passed about 200 ft over him. Cessna did not have altitude encoding, but TCASII would have given me an earlier alert to his proximity. TCASII is most valuable under VMC conditions when GA aircraft are flying. Perhaps TCASII should be a no-go item if it's inoperative. It will be on my future flts.

Title: AN MD88 CAPT DESCRIBED AN NMAC HE EXPERIENCED WHILE ON APCH TO RWY 6L AT DAY, OH.
Narrative: DISPATCHED WITH TCASII INOP. DAY WX WAS VFR, UNLIMITED VISIBILITY. ESTABLISHED ON FINAL, TRACKING THE ILS ON A VISUAL APCH, JUST OUTSIDE THE OM TO RWY 6L. APCH CALLED TFC 12 O'CLOCK POS, TYPE AND ALT UNKNOWN. AT THE SAME MOMENT, I ACQUIRED VISUALLY AN OLDER, DARK BLUE CESSNA MOVING R TO L, DIRECTLY IN FRONT OF ME AND SOMEWHAT LOWER. I SLOWED OUR DSCNT AND PASSED ABOUT 200 FT OVER HIM. CESSNA DID NOT HAVE ALT ENCODING, BUT TCASII WOULD HAVE GIVEN ME AN EARLIER ALERT TO HIS PROX. TCASII IS MOST VALUABLE UNDER VMC CONDITIONS WHEN GA ACFT ARE FLYING. PERHAPS TCASII SHOULD BE A NO-GO ITEM IF IT'S INOP. IT WILL BE ON MY FUTURE FLTS.
