Then again, what if there is a backstory to why the engine exploded? Just read an article (an excellent one in Vanity Fair) on the rapid growth of airlines outsourcing their maintenance to underbidders in China and Central America. This has been going on for years, as an airline pilot I've seen the result of this first hand - and it ain't pretty.
In today's world of absentee regulatory agencies, financial penalty of screwing up is the only thing keeping airlines even remotely in compliance, and only just barely in some instances. It is only when something goes badly wrong, that the lawsuits spin up and expose a lot of these lapses that should have been stopped by a regulator.
So sue away folks. I have no loyalty to these accountant managed airlines or manufacturers. They've destroyed this profession and many others by lying and cheating. If this malfunction was in any way related to cutting corners at some point along the required processes, then why should we defend that?
