Pretty sure that very aircraft had another partial eng failure back in 2008 (pretty sure the engine in it at the time was at the end of its life). WOY was very lucky a few months back. Oil useage off the charts, one or 2 pilots eventually refused to fly it and were shown the door. As it turns out the engine was not far off failure by the time a now ex company maintainer took it on himself to investigate the cause of the constant oil consumption. Lets hope that the upcoming audit is thorough.
