That is how it works in civil aviation. The NTSB does a pretty good job of dissecting and disseminating accident data. The FAA, in the other hand, is lacking in action and ability.
The not so joking saying about feds at the FAA is they are a bunch of disgruntled pilots who couldn’t find a real job in aviation. Now they are a bunch of woke political appointees.
The 767 in question is likely 25-30 years old. It most likely also doesn’t have many original parts left on it.

Gee, I would hope not! Could you imagine the structural fatigue on a 30-year aileron?
FedEx is still buying new 767’s.
