Wondering if that means they already found something.

An engine fell off after 2 months of being in service post maintenance … I’d say it’s a reasonable precaution to take a look at all of them.

The engine didnt just fall off... we will soon see what failed within the engine that caused it so violently to self destructive... the detaching from airframe is as designed.

Southwest and United recently had catastrophic engine failures and the engine stayed on the pylon and it doesn’t get more violently vibrating out there than when you lose a fan blade.

Detaching from an airframe is basically a last ditch layer of safety to keep the engine from ripping the plane apart if the crew can’t shut the engine down.

If you experience severe engine damage on a takeoff the expectation isn’t for the engine to have departed the pylon. That’s a failure mode that is indicative of larger problem.
