Qantas flight QF1402, a DHC-8-315Q Dash 8 (VH-TQH), was involved in a runway incursion incident with a Piper PA-28-161(VH-ENL) at Mildura Airport, VIC (MQL).
The crew of VH-TQH commenced their take-off from runway 09. A short time later, the pilot of VH-ENL commenced their take-off from runway 36. As the pilot of VH-ENL started their take-off roll, they observed VH-TQH airborne and climbing as it crossed runway 36. As VH-TQH had now crossed runway 36, the pilot of VH-ENL elected to continue their take-off.
Contributing factors
- Both aircraft crews had incorrect mental models of local traffic at Mildura and neither crew spoke directly to the other to ascertain position and intentions before take-off.
- Both Dash 8 crew were focussed on receiving the final information from air traffic control when the CTAF broadcast from the other aircraft occurred, and the volume for the radio tuned to the CTAF frequency had been turned down. Their focus and reduced radio volume, and an over transmission, likely led to an incomplete comprehension of traffic at Mildura during the time compressed phase of pre-departure.
- Due to topography and buildings at Mildura Airport, aircraft are not directly visible to each other on the threshold of runway 09, 27 and 36. The lack of a requirement for mandatory rolling calls increased the risk of aircraft not being aware of each other immediately prior to take-off.
- The Dash 8 crew assumed there was no traffic at Mildura and elected to not make a rolling call on runway 09 before take-off. The PA 28 pilot was aware that the Dash 8 was backtracking, but was not aware it had begun its take-off roll.
- The PA‑28 pilot broadcasted an incorrect runway direction for Mildura Airport in both the 'taxiing' and 'entering and backtracking' radio calls.
