Air safety authorities have praised an airline crew for their handling of an engine failure incident during take-off. The crew of Qantas flight QF520, departing from Sydney to Brisbane in November 2024, experienced an engine failure on the aircraft’s right side shortly after take-off, with 181 passengers on board.

Despite the engine failure alert, the crew proceeded with the take-off as the aircraft had surpassed the critical speed for aborting. ATSB Chief Commissioner Angus Mitchell acknowledged the crew’s swift and decisive response, declaring an emergency and initiating necessary checklists while planning a return to Sydney.

Passenger Mark Willacy recounted feeling a sudden jolt and hearing a noise as the aircraft’s wheels left the ground, signaling an issue. The pilot informed passengers of the engine problem and maneuvered the plane over Sydney for about 15 minutes before successfully landing with only one operational engine.

Mitchell commended the coordinated efforts of the flight and cabin crew, ARFFS, and air traffic controllers in ensuring a safe return to Sydney for everyone on board. The engine failure was attributed to a fatigue crack, scheduled for replacement shortly after the incident due to nearing the recommended threshold by manufacturer CFM International.

Following the incident, CFM International reviewed its CFM56-7B engine fleet and confirmed that despite previous engine failures from similar cracking, the specific engine on QF520 still met reliability standards and regulatory requirements. The introduction of newer high-pressure turbine blade configurations was also mentioned as a proactive measure.

Overall, the incident highlighted the professionalism and collaboration of all involved parties in managing the emergency situation effectively and ensuring a safe outcome for the passengers and crew.
