On 20 December 2012, a PW4168A-engined Airbus A330-200 was climbing through FL220 after departing Phuket, Thailand, at night when sudden uncontained left engine failure occurred. Engine shutdown and initiation of a return was followed by loss of the green and then blue hydraulic systems. Shortly after this, a relatively uneventful landing followed with only minor damage but “without pilot assessment or knowledge of the safety margin." As the findings of the investigation raised still-relevant concerns about the way this multiple-failure scenario was handled, it was felt useful to publish the 148-page final report eleven years later.
