Narrative:

During initial radar vectors for arrival to sanford, fl, orl approach advised flight X. To turn right, heading 270 degrees, maintain 3000 ft, radar vectors for ILS runway 9L. Flight X acknowledged and performed as cleared. ATC said to flight X, maintain 2000 ft. Flight X acknowledged and continued descent. ATC flight X, said to turn left, heading 180 degrees for visual approach runway 9L. Flight X flight X said requesting radar vectors onto the localizer for the ILS runway 9L. ATC answered turn right heading 230 degrees for the ILS approach runway 9L. Flight X: acknowledged and performed as cleared. (After a couple of mins) ATC flight X, said to turn left 180 degrees, maintain 2000 ft. Flight X acknowledged and performed as cleared. (Delayed on this heading until we passed through the localizer.) ATC flight X, turn left, heading 070 degrees to intercept the localizer. Maintain 2000 ft until semco, upon intercept, you are cleared for the ILS approach runway 9L. During the captain's readback, we received an RA, alarming us of 'traffic, climb.' we initiated a climb and, almost immediately after, approach control directed us to climb to 2100 ft. I stood up from my seat to get a better view below us and stated that a small aircraft, which looked like a cessna, was passing directly below us. The captain took note of the separation indicated on the TA/RA, which read 300 ft.

Title: NMAC BTWN A B727 AND A C172 NEAR 2000 FT 8 MI W OF SFB, FL.

Narrative: DURING INITIAL RADAR VECTORS FOR ARR TO SANFORD, FL, ORL APCH ADVISED FLT X. TO TURN R, HDG 270 DEGS, MAINTAIN 3000 FT, RADAR VECTORS FOR ILS RWY 9L. FLT X ACKNOWLEDGED AND PERFORMED AS CLRED. ATC SAID TO FLT X, MAINTAIN 2000 FT. FLT X ACKNOWLEDGED AND CONTINUED DSCNT. ATC FLT X, SAID TO TURN L, HDG 180 DEGS FOR VISUAL APCH RWY 9L. FLT X FLT X SAID REQUESTING RADAR VECTORS ONTO THE LOC FOR THE ILS RWY 9L. ATC ANSWERED TURN R HDG 230 DEGS FOR THE ILS APCH RWY 9L. FLT X: ACKNOWLEDGED AND PERFORMED AS CLRED. (AFTER A COUPLE OF MINS) ATC FLT X, SAID TO TURN L 180 DEGS, MAINTAIN 2000 FT. FLT X ACKNOWLEDGED AND PERFORMED AS CLRED. (DELAYED ON THIS HDG UNTIL WE PASSED THROUGH THE LOC.) ATC FLT X, TURN L, HDG 070 DEGS TO INTERCEPT THE LOC. MAINTAIN 2000 FT UNTIL SEMCO, UPON INTERCEPT, YOU ARE CLRED FOR THE ILS APCH RWY 9L. DURING THE CAPT'S READBACK, WE RECEIVED AN RA, ALARMING US OF 'TFC, CLB.' WE INITIATED A CLB AND, ALMOST IMMEDIATELY AFTER, APCH CTL DIRECTED US TO CLB TO 2100 FT. I STOOD UP FROM MY SEAT TO GET A BETTER VIEW BELOW US AND STATED THAT A SMALL ACFT, WHICH LOOKED LIKE A CESSNA, WAS PASSING DIRECTLY BELOW US. THE CAPT TOOK NOTE OF THE SEPARATION INDICATED ON THE TA/RA, WHICH READ 300 FT.
