ATSB releases preliminary reports on Sydney Airport safety ‘incidents’

The Australian Transport Safety Bureau has released preliminary reports from four of its six ongoing investigations into aircraft coordination and conflict incidents at Sydney Airport in July and August 2026, as well as a data analysis report into runway confliction occurrences at major Australian airports. The preliminary reports do not contain findings or analysis, which will come with the final reports. Instead, they outline the sequence of events in each of the occurrences and outline important contextual and operational information. Read the preliminary reports Air traffic control procedural error and serious runway incursion involving Bombardier DHC-8, VH-QOC, and Boeing 737-800, VH-XZG, at Sydney Airport, New South Wales, on 27 July 2026 Taxiing proximity event involving Airbus A320, VH-VQJ, and Boeing 777, A7-BEU, at Sydney Airport, New South Wales, on 9 August 2026 Runway incursion and rejected take-off involving Boeing 737-8SA, VH-IJQ, and Boeing 737-838, VH-XZH, at Sydney Airport, New South Wales, on 9 August 2026 Taxiing conflict involving Airbus A321, VH-OGA, and Boeing 737, VH-VXL, at Sydney Airport, New South Wales, on 18 August 2026 Read the statistical research report Analysis of runway confliction occurrences at major Australian airports, 2016–2026 The four occurrences comprise: 27 July – a runway incursion where a Qantas Boeing 737 was cleared to cross in front of a QantasLink Dash 8 aircraft in its landing roll. 9 August – a taxiing proximity event where a Jetstar A320 braked abruptly to avoid a Qatar Airways Boeing 777 under tow. A flight attendant aboard the A320 fell during the braking and sustained a fractured wrist. 9 August – a runway incursion where a Qantas Boeing 737 was cleared to cross the runway in front of a Virgin 737 that had just been cleared for take-off. 18 August – a taxiing conflict where a Qantas A321 had to brake to let a Qantas Boeing 737 pass in front of it. “While air traffic control involvement in each occurrence is still being examined, we can say based on information detailed in our preliminary reports that staff resourcing within Sydney Tower at the time of many of the occurrences has emerged as a recurring area of enquiry,” ATSB Chief Commissioner Angus Mitchell said. “These investigations will look to understand the significance of staff resourcing pressures within the tower, specifically, the practice of combining operational roles, the routine reliance on overtime to fill shifts, and training or supervision activities being conducted alongside operational duties.” The ATSB stresses it has yet to determine whether staff resourcing factors directly contributed to any occurrence, or whether they were simply underlying conditions that were recognised and being effectively managed by Airservices, Australia’s air traffic services provider. The preliminary reports also note that Airservices’ roster modelling predicted elevated fatigue risks for staff at the time of many of the occurrences. “It is important to note that an elevated fatigue risk in and of itself does not mean a controller was fatigued, or that fatigue influenced their performance,” Mitchell said. “We are examining the effectiveness of the measures in place to manage this identified risk.” To understand the broader context of the six Sydney conflict investigations, the ATSB has also released a statistical research report on ground-based aircraft conflicts covering Australia’s five busiest major airports from 2016 to August 2026. This report examined whether 11 recent occurrences recorded at Sydney Airport over July and August of this year reflected a growing post-COVID trend, or a more localised pattern. “Nationally, over the decade, reported ground-confliction rates have remained broadly steady,” Mitchell noted. “However, Sydney recorded the highest confliction rate per aircraft movement post COVID among the major airports, around 20% above the national average. This should however be viewed in the context of Sydney Airport being the most complex in the country. The analysis also found increases specific to Sydney in potentially high consequence occurrences, including runway incursions, taxiway near collisions and losses of separation attributed to air traffic control actions.” Mitchell acknowledged that a Sydney Airport Air Traffic Control Working Group led by the Department of Infrastructure, bringing together Airservices, CASA, the airlines, unions and Sydney Airport, has been established, to build a shared understanding of these challenges, and a pathway to collaborative solutions. In addition, Airservices is implementing its own Service Resilience Plan for Sydney Airport. “The ATSB does not investigate to apportion blame or liability. Our role is to independently examine the evidence, identify any systemic safety issues that may emerge, and bring them to light early and transparently so those best placed can consider whether any immediate and ongoing safety risks are being effectively managed,” Mitchell said. The ATSB will release final reports, containing findings and the analysis to support those findings, at the conclusion of each investigation. If at any time during the investigations critical safety issues are identified, the relevant stakeholders will be notified immediately so that they can take addressing safety action.
