On 25 November 2010, a De Havilland Canada DHC-8-202 aircraft, registered VH-SDA (SDA), was taxied to runway 03 at Port Macquarie, New South Wales for a scheduled passenger service to Sydney.

After lining up on runway 03, the pilot in command (PIC) of SDA observed a traffic return on the aircraft's traffic alert and collision avoidance system (TCAS) indicating that an aircraft was behind them, about 400 ft above and descending. As a precaution, the takeoff was expedited.

At the same time, a Beech Aircraft Corporation 58 aircraft, registered VH-VFG (VFG), was on final approach to runway 03. After observing SDA commence the take-off, the crew initiated a go-around and positioned the aircraft to the right of the runway centre line to maintain separation with SDA.

At about 600 ft, the crew of SDA noted that the TCAS was indicating that VFG was about 100 ft above and climbing. The PIC of SDA discontinued the aircraft's climb and turned left onto a westerly heading.

Both crews attempted to contact each other on the Port Macquarie common traffic advisory frequency (CTAF), but received no response. The crews eventually established communications on the Brisbane Centre frequency.

Following the incident, the copilot of SDA reported that he may have mistuned the CTAF prior to taxiing. A subsequent engineering inspection by the operator determined that the aircraft's radio transceiver was faulty.

The operator of SDA has advised the ATSB, that as a result of this incident, a safety alert was issued to pilots emphasising the radio requirements for when operating on the CTAF. In addition, the operator also intends to conduct a review of their CTAF operating procedures.
