The ATSB is investigating a reported separation issue involving Rex Airlines Saab 340B, registered VH-ZLV, and a Beech Aircraft B200, registered VH-WXB, at Brisbane West Wellcamp Airport, Queensland, on 21 October 2021.

It was reported that the two aircraft were inbound for Brisbane West Wellcamp and had established communications with each other on the common traffic advisory frequency (CTAF). Both crews agreed that ZLV would join the circuit first followed by WXB.

At about 0830 AEDT, while on the downwind leg for runway 12, the crew of ZLV observed WXB cross their flight path about 300 ft below and received a traffic collision avoidance system (TCAS) resolution advisory (RA). The crew disconnected the autopilot and commenced a climb until they were clear of conflict. Shortly after, the pilot of WXB observed ZLV out to the left of the aircraft. The crew of ZLV contacted the pilot on the CTAF and notified them of the TCAS alert. Both crews had each other visible and agreed that ZLV would go as number one in the circuit followed by WXB. Both aircraft re-joined the circuit and landed safely.

The evidence collection phase of the investigation will include interviewing the flight crews involved, and reviewing recorded communications, flight data and relevant documents.

A final report will be released at the conclusion of the investigation. Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
