[Donnie Darko] What did the FAA conclude after investigating a jet engine (with no apparent origin) falling onto a house in Middlesex, Virginia? What about the second investigation 4 weeks later when a jet flying over Middlesex loses an identical engine that is never found?

The second investigation never happens; that only occurs in the "pocket universe", which ends once the loop is complete. So that point is moot.

As for the first investigation, however, that one takes place after it crushes Donnie. That investigation would be taken even more seriously than it was in the pocket universe, due to the fact that there was a fatality. Eventually, its "twin" would be located and the FAA would be forced to confront a true impossibility. So like all good government agencies, it would eventually close the investigation and classify the entire thing. This lack of answers would eventually destroy the Darko family, never to recover.
