ATSB: Qantas 737-800 engine-failure incident driven by turbine-blade crack; crew took decisive action after failure at/after V1
Australia’s ATSB says a Qantas Boeing 737-800 returned to Sydney after a loud bang from the right engine during the take-off roll on 8 November 2024 (QF520 to Brisbane). Investigators found the event stemmed from a turbine-blade crack and noted the failure occurred after V1, limiting abort options.
