A shortage of air traffic controllers caused flight cancellations and significant delays at Sydney Airport on Friday morning, according to Airservices Australia, the federal agency responsible for managing the country’s air traffic.
Airservices Australia introduced temporary measures to control traffic flows and safely manage demand after an unexpected staffing shortfall. The restrictions resulted in around 14 inbound flight cancellations, while some flights were delayed by more than an hour.
The disruption adds to a series of operational challenges facing Australia’s busiest airport as Airservices Australia continues to deal with staffing shortages. It also comes as authorities investigate several recent near-miss incidents involving aircraft at the airport.
Peter Curran, Deputy Chief Executive of Airservices Australia, told a Senate committee examining the aviation sector that unexpected absenteeism had affected staffing levels.
“Last night, at relatively short notice, we had some unplanned absenteeism, which we weren't able to recover from,” Curran said. He added that having one fewer controller in the tower that morning had contributed to significant delays.
The traffic management measures were withdrawn at 8:15 a.m. local time, or 2215 GMT on Thursday, after operating conditions improved. Minor delays persisted through the remainder of the morning, but flight schedules had largely returned to normal by the afternoon.
An Airservices Australia spokesperson said the agency was coordinating with airlines to minimise delays and reduce the impact on passengers.
Sydney has 49 air traffic controllers, but 41 are required for normal operations. Curran said eight controllers were unavailable because of long-term absences, leaving limited capacity to handle unexpected staffing shortages.
“We've had some staffing challenges in the last number of weeks since July ... and we have some moments where that can become somewhat acute. Today's an example of that,” he said.
Airservices Australia said it was working to recruit additional air traffic controllers and improve arrangements for bringing in extra staff when operational pressures increase.
