Is there any way of knowing how many times a single engine has shut down on the same type, at the same stage of flight? If there's a systemic problem that affects engines infrequently, statistics suggest that sooner or later both engines will be affected at the same time. That would make the BA38 incident just 'sooner' rather than later.
I'm sure the AAIB are combing the figures for clues, but I'd be interested to know how many incidents of single engine throttle-up 'issues' at any stage of the flight, on this type, professionals are aware of?
