As for the event. It doesn't matter that it occured on pre delivery, delivery or in service, it is still an engine shut down on a new engine. This should concern us all.
No doubt that it will concern GE, Boeing and AF, but it certainly should not be a concern to all
The flight wasn't even in revenue service and for all we know might not even carry the latest Service Bulletins,
prior to entering service.
An economic concern to the bean counters but not necessairly an operational concern
