but isn't it a little worrying though that this was the third engine failure this plane had had?
Only from a maintenance / repair point of view (until proved otherwise.) The one I fly was sent to a maintenance facility at Coventry for routine maintenance and was returned, several weeks later, with THREE time-expired components still in situ - one of which was the alternator. It made a swift trip down to Bristol where they, and another problem which manifested itself whilst it was there, were dealt with in a matter of two days. It only took two days because the new problem was unexpected and parts had to be obtained. Did something similar happen to this aircraft? Who knows? It will be interesting to see what the Swedish AAIB discover.
