Air carrier flight crew on final approach to JAN reported a NMAC with traffic departing MBO airport.
Synopsis
Air carrier flight crew on final approach to JAN reported a NMAC with traffic departing MBO airport.
Narrative
We were cleared for a Visual Approach to Rwy 16L at JAN and backing ourselves up with an ILS 16L. We were approaching on a five mile base and began our turn to final and began to descend. An unknown aircraft took off heading south from MBO and began climbing to pattern altitude. A TCAS alert activated showing an amber symbol below us. Tower made a traffic advisory call. We did not have traffic in sight. TCAS symbology indicated the contact was directly below us. When TCAS indicated a vertical separation of 400 feet I ordered a go around. The PF initiated a go around and vertical separation rapidly increased. Tower then advised we were not in conflict and asked if we wanted to resume the approach. I declined to resume; continued the go around; and requested vectors back to final. Approach then vectored us to a downwind and cleared us for a visual approach to Rwy 16L. We then landed without incident.Cause: Loss of vertical separation with traffic at MBO. Suggestion: Add an entry to Company operations pages that MBO traffic pattern altitude is very close to a 3 degree glideslope to Rwy 16L at JAN
Second reporter narrative
We were on the visual approach to runway 16L into JAN. We were fully configured and turning base to final when we got a traffic alert from the TCAS and a radio call from tower stating traffic was below us and had just departed MBO. Our TCAS showed they were -400 feet and right below us. The Captain called for a go around and I immediately complied. We flew runway heading up to 3000 ft then back to approach who vectored us around for a second attempt at the visual approach which was successful with no further incident.
