Investigation after fourth close call at Sydney airport in less than a month

Australia has launched an investigation into a fourth air-traffic-control incident at Sydney airport in less than a month, after multiple close calls involving aircraft cleared to intersect the same areas. The Australian Transport Safety Bureau said a Qantas Airbus A321 departing for the Gold Coast braked on Tuesday to avoid a Qantas Boeing 737 that had been cleared to continue along a taxiway while the Airbus was cleared to turn onto it. While there was no immediate collision risk, the ATSB is examining whether factors overlap with three other incidents since late July. A preliminary report is due in 6–8 weeks.
