The AF A380 the other day had a similar event.
Anyway, do we know of any other CFM 56 incidents say the last 30 years of cowl separation due to fan blade separation or the likes.
Southwest Airlines flight 3472, 2016. Same engine, same type,
same airline, and very similar event (IF this one is a blade off) including fuselage damage and depressurisation (occurred around the same altitude as well).
As far as I can find there are no other similar CFM 56 incidents, but I haven't done a lot of research to be sure on that. However, if these are the only two then question is are Southwest really unlucky or doing something different. As you say, there are a lot of CFM 56s out there.
