 The aircraft was repaired and returned to service with Korean Air on 3 June 2016.A later JTSB investigative report, released on 26 July 2018, discussed a significant number of problems related to the failure and the response of the crew and passengers to it.These included poor maintenance standards that overlooked a crack growing in the LP turbine disc in the engine created by metal fatigue that eventually failed, the failure of the crew to locate the list of emergency procedures for use in such an emergency, beginning evacuation of the aircraft whilst the engines were still turning meaning there was a risk of passengers being blown away by the engines, and passengers ignoring instructions to leave luggage behind when using the evacuation slides risking piercing of the slides.
