Narrative:

We were heading approximately 150 degrees at 3000 ft being vectored by center for visual approach to gnv when we received a TA and then an RA on the TCASII to descend. Traffic was not in sight and we complied. At approximately an altitude of 2600 ft we sighted the traffic which looked like a single engine low wing aircraft of type small aircraft. We advised center and he said there was no traffic. We told him that we got a visual and that altitude looked good and he said he would report the event. When we were later handed over to gnv tower they said we were handed over with no position report.

Title: TCASII RA FOR ACR ON VECTORS FOR APCH.

Narrative: WE WERE HDG APPROX 150 DEGS AT 3000 FT BEING VECTORED BY CTR FOR VISUAL APCH TO GNV WHEN WE RECEIVED A TA AND THEN AN RA ON THE TCASII TO DSND. TFC WAS NOT IN SIGHT AND WE COMPLIED. AT APPROX AN ALT OF 2600 FT WE SIGHTED THE TFC WHICH LOOKED LIKE A SINGLE ENG LOW WING ACFT OF TYPE SMA. WE ADVISED CTR AND HE SAID THERE WAS NO TFC. WE TOLD HIM THAT WE GOT A VISUAL AND THAT ALT LOOKED GOOD AND HE SAID HE WOULD RPT THE EVENT. WHEN WE WERE LATER HANDED OVER TO GNV TWR THEY SAID WE WERE HANDED OVER WITH NO POS RPT.
