On 22 December 2023, a new ATSB Occurrence Brief details, a Bombardier DHC-8 was operating a scheduled passenger flight between Adelaide, South Australia and Port Lincoln, South Australia. During final approach to runway 19, the pilot of a Van’s RV-6 made a broadcast on the Port Lincoln common traffic advisory frequency (CTAF), advising that they were taxiing to runway 15 for a departure.
The crew of the DHC-8 acknowledged the RV-6’s broadcast, relayed their current position, and their intention to backtrack on runway 19 before taxiing to the passenger terminal via runway 15 and taxiway Bravo. The pilot of the RV-6 acknowledged and advised they would hold at the threshold of runway 15 until the DHC-8 was established on taxiway Bravo and clear of runway 15.
After landing, the DHC-8 turned around using the turning node at the end of runway 19. They then backtracked on the runway and as they approached the intersection of runway 19 and 15, the crew heard the pilot of the RV‑6 make a rolling call. The crew of the DHC-8 immediately stopped and advised the RV-6 pilot of their position and requested the RV-6 pilot stop their take-off run. However, the RV-6 continued and became airborne prior to the runway intersection. After the RV‑6 had passed, the crew of the DHC-8 noted that the right side of their aircraft was infringing the gable markers for runway 15.
The pilot of the RV-6 stated that upon reflection, they should have waited for the DHC-8 to backtrack and use runway 15 to exit via taxiway Bravo as originally arranged. They advised that their judgement had been affected due to the build‑up of excessive heat inside the cockpit associated with the aircraft’s bubble canopy.
--Safety message--
Runway incursions and other runway separation issues continue to be a significant risk to safe aviation operations and are a key global safety priority. When operating at a non-towered airport, pilots have responsibility for maintaining separation with other aircraft. One of the key ways of doing this is the clear communication of intentions and ensuring that any changes to agreed plans are communicated in advance. This allows involved crews time to assess and, if necessary, revise their operation.
The ATSB SafetyWatch highlights the broad safety concerns that come out of our investigation findings and from the occurrence data reported to us by industry. One of the safety concerns is reducing the collision risk around non-towered airports.

Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.
