Australian aviation investigators have released preliminary findings into a series of runway incursions at Sydney Airport, revealing that a passenger jet was forced to brake abruptly to avoid a collision with a towed aircraft — the fourth such incident in three months at the country's busiest hub.
The Australian Transport Safety Bureau (ATSB) released the reports on Sept. 30, detailing four separate occurrences involving passenger aircraft between late July and mid-August. The incidents have raised questions about safety protocols and air traffic control operations at the major international gateway.
The most serious incident occurred on Aug. 9, when a Jetstar Airbus A320 was forced to brake hard to avoid a Qatar Airways Boeing 777 being towed across its path. A flight attendant aboard the Jetstar aircraft fell during the sudden braking and fractured her wrist, according to the ATSB. On the same day, a Qantas Boeing 737 was cleared to cross a runway in front of a Virgin Australia 737 that had just been cleared for takeoff.
The sequence of events began on July 27, when a Qantas Boeing 737 was cleared to cross a runway in front of a QantasLink Dash 8 that was landing. Nine days after the Aug. 9 incidents, a Qantas Airbus A321 had to brake while taxiing to allow another Qantas 737 to pass in front of it.
Sydney Airport said in a statement that safety remains its highest priority. «We will continue to support the Minister and Airservices as they work through the preliminary findings and the appropriate actions,» a spokesperson said. «We await the final reports and any recommendations arising from the ATSB's investigations.»
Investigators have identified staffing levels at the airport's control tower as a recurring area of inquiry, though they have not determined whether staffing factors directly contributed to any of the incidents. ATSB Chief Commissioner Angus Mitchell said the investigations will examine «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.»
Fatigue among controllers has also been raised as a concern, though investigators cautioned that a heightened risk of fatigue does not necessarily mean controllers were tired at the time of the incidents. «We are examining the effectiveness of the measures in place to manage this identified risk,» Mitchell added.
The incidents come as Sydney Airport recorded the highest rate of ground conflicts per aircraft movement among Australia's major airports in the post-COVID period, about 20 percent above the national average, according to a separate ATSB analysis. Mitchell noted that the findings should «be viewed in the context of Sydney Airport being the most complex in the country.»
The ATSB's preliminary reports do not assign blame but are intended to identify safety issues and recommend improvements. Final reports are expected to follow as the investigations continue. The airport has pledged to cooperate fully with the process.
