Here’s my thought, yes PTSD is a thing, but saying the airline failed to maintain the plane is a load of crap. The airline of course maintained the plane and inspect according to Boeing and local regulations, since the airline was a major airline. But, it can never be 100% guaranteed that an engine won’t fail, besides pilots train for this, you train for stuff to go wrong knowing that even though the plane is maintained, stuff still can go wrong. Suing an airline because an engine failed is, IMHO really bad form, especially since it was only one engine, the plane landed safely and everyone survived. Once again, PTSD is a thing and shouldn’t be ignored, but suing the airline here is really bad form and just being a jerk.
