well I would believe that QA might be going thru an unlucky streak with regards to engine inflight problems.
as I have heard it's not an Airbus or Airline problem.. the real problem lyes with the engine manufacter.. GE.
although GE has since reported MANY inflight failures.. QA was unlucky enough to be operating the Aircraft that had the first inflight failures of a GE engine attached to a Airbus A330 aircraft..
it's just a real good engine re-light system designed within the aircraft that seems to saves the day.. and manages to relight the engines within seconds ( usually 30 to 45 sec) everytime.. nice.. and as mentioned by Mr Krunch.. good job to all involved.
