From what I’ve read, the Ghanaian regulators have demanded that that specific aircraft not be flown within their jurisdiction because they don’t like the recurring issue with the fuel imbalance (…and advised that Delta flies newer planes because Ghanaians don’t like the old ones)

The FAA/EASA not being concerned by it (from what we know), doesn’t mean that there isn’t a possible safety issue to investigate.

It’s also easy to have politics and safety i.e. regulation mix in ways that aren’t so black and white. Consider the time it took for the 737 Max to be recertified in the rest of the world vs the US. Do you think that was all safety? Or some combination of safety and politics?

So no, I don’t think it’s possible to categorically state that it has nothing to do with safety.

A fuel imbalance happening twice is not a "recurring issue". It's a problem that wasn't fixed correctly. It may or may not concern you, depending on your level of knowledge about aviation, to know that when it comes to relatively minor issues like this, this kind of thing actually happens all the time — the maintenance engineer will carry out a documented series of steps to test the system, find that everything tests OK, and release the aircraft back to service. Meanwhile some intermittent fault is still present, that didn't show up during the test, and it happens again on the next flight or a few flights later. Eventually the tech log entries give enough clues to identify the problem or it happens during a test, and the issue is solved. No sane regulator would ban an aircraft for this kind of situation — a version of it happens daily worldwide, including on whatever your own favourite airline is.

Yeah, we’re gonna have to agree to disagree.

Do I personally think that the 2x fuel imbalance is a problem? Nope, I’d happily get on that plane

Could this situation become a safety issue? Yes it could.

Is it possible that there’s more to this situation than safety? Yeah, probably. Maybe they want shiny new planes on the route. But also, the passengers are paying customers with consumer rights - these are being enforced

Are the Ghanaian authorities not a sane regulator? I’ve got no reason to believe they aren’t being proper regulators. There is a possible safety issue that’s well within their mandate.

What happens when you’re dealing with regulators is if you’ve got a good relationship with them, then all the optional stuff (and some of the mandatory stuff) is optional. If not, then you’re gonna have to check every single box and then some. See Boeing in the US vs Europe.

Call it politics, call it whatever but it is what it is

Agree. Politically a government is responsible for giving its citizens a sense of security… maybe more so than actual security. Ghana and the US were both doing that in this scenario. Whether the fear is 100% reasonable or not is ultimately irrelevant. “We fixed it, no worries, go back to being productive.”

Then of course there’s the reality of them abusing fear of security to steer the herd, but I don’t want to wander down that rabbit hole.
