Human Factors; Procedure
[Aircraft Y] was on a practice VFR ILS 24 approach at about a 5 mile final and was instructed to break off the approach and make a right 360 to follow [Aircraft X]. [Aircraft X] was on a 6 mile final for a visual approach. The helicopter [Aircraft Y] was breaking off the approach and flying to the northeast north of the 24 approach course. [Aircraft X] received a traffic alert saying the traffic was 200 feet below so they began to climb. The helicopter was north of the approach course at that time. Break the helicopter approach off sooner and do a wider 360 so the TCAS does not go off in [Aircraft X].
While on final approach approximately 8 miles out Tower told me about a helicopter ahead. I told [them] I was looking and I did not see him but had it on TCAS. [ATC] told me to continue and report 6 miles out; I am not sure if [ATC] had cleared me to land yet or not. [ATC] then told the helicopter to depart the area as I was coming in. Shortly thereafter I got an aural warning of an aircraft at 200 feet below me and at a very close distance; then it went to 100. I took evasive action to avoid a collision; I never saw the helicopter. [ATC] apologized and had me call the tower when I landed. [ATC] apologized again and said [they] would need to file a report. I gave [them] my information.
PNE Controller and transport pilot reported a NMAC with a helicopter while on visual approach.
