Air traffic control staffing pressures at Sydney Airport are under scrutiny after a series of near-misses at Australia’s busiest airport, including one incident classified at the most serious level on the international scale.
The Australian Transport Safety Bureau (ATSB) has released preliminary reports into four incidents as part of investigations into six events at Sydney Airport this year. The reports do not make final findings or recommendations but outline the circumstances surrounding the incidents and areas requiring further examination. Pasted markdown
Sydney Airport Tower Staffing Becomes Key Focus
ATSB Commissioner Angus Mitchell said staffing arrangements inside Sydney Airport’s air traffic control tower had emerged as a recurring area of inquiry across several investigations.
“These investigations will look to understand the significance of staff resourcing pressures within the tower,” Mitchell said.
“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 preliminary material does not conclude that staffing directly contributed to any of the near-misses. Investigators are instead examining whether staffing arrangements represented underlying operational conditions being managed by Airservices Australia.
Fatigue Risks Also Under Examination
The ATSB has also identified potential fatigue risks associated with the structure of air traffic services rosters.
“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.”
The distinction is significant because the investigations remain ongoing, and the preliminary reports are not intended to determine blame or establish final causes.
July Near-Miss Classified at Most Serious Level
One of the most significant incidents occurred on July 27 and involved a Boeing 737 and a Bombardier DHC-8.
According to an ATSB statistical report covering Australia’s busiest airports, the event was the first near-miss of its type recorded at Sydney Airport and only the third nationally since runway incursion severity tracking began in 2003.
Mitchell said the incident was categorised at “the most serious level on the international scale”.
The event adds to concerns surrounding ground operations at Sydney, where high aircraft movements and a complex runway and taxiway environment require close coordination between pilots, ground crews and air traffic controllers.
Multiple August Incidents Under Investigation
Several other incidents are also being examined.
On August 9, a Jetstar Airbus A320 reportedly braked sharply on a taxiway to avoid a Qatar Airways Boeing 777 that was being towed. A flight attendant suffered a fractured wrist during the incident.
Later the same day, a Qantas Boeing 737 was mistakenly cleared to cross a runway ahead of a Virgin Australia Boeing 737 that was preparing for takeoff.
Another incident occurred on August 18, when a Qantas Airbus A321 was forced to brake to avoid another Qantas Boeing 737 passing ahead of it.
The sequence of events has increased attention on operational procedures and staffing at Sydney Airport, although investigators have not yet determined whether the incidents share a common cause.
Sydney Records Higher Ground-Conflict Rate
Mitchell said reported ground-confliction rates across Australia had remained relatively stable over the past decade.
“Nationally, over the decade, reported ground-confliction rates have remained broadly steady,” Mitchell said.
“However, Sydney recorded the highest conflict rate per aircraft movement post-COVID among the major airports, around 20 per cent above the national average.
“This should, however, be viewed in the context of Sydney Airport being the most complex in the country.”
Sydney Airport is Australia’s busiest aviation hub and handles a substantial mix of domestic and international aircraft, making its airfield operations among the most demanding in the country.
The ATSB investigations will continue examining staffing, fatigue management, operational procedures and the circumstances surrounding each incident. As Mitchell stressed, “The ATSB does not investigate to apportion blame or liability.”
