Yeah, that doesn't sound like an XP service pack at all.

It's amusing that I got downvotes for someone else's analogy being bad.

It’s a bad analogy but maybe responding to the analogy in a way that doesn’t apply to the airplane problem came across as confusing and irrelevant.

Personally I don't think it's irrelevant to try to cut off an unhelpful analogy, those things sometimes act like black holes. But point taken.

Nah I get that, it was just ambiguous whether you were cutting it off or falling into the black hole, but maybe that’s just me :)

The black hole would be trying to elaborate a whole lot on top of a completely broken foundation, or trying to fix the analogy in intense detail when you should start from scratch, etc.

I just said one line about how that analogy didn't fit.

Theire should be after accident reclassifications to new planes.

What makes you think there isn’t a review process?

There is a process for “special certification review”, some of those end with changes (typically airworthiness directives); others validate the airplane as meeting certification and safe.

Lear 60, MU-2, DC-10, MD-11, ATR-72, R22/R44 helicopters, Piper Malibu, CE-441, and Bonanza have all undergone the SCR process and continue to fly having been validated as safe/conforming (some with changes to airframe or procedures)

To my knowledge, only the DC-6 and Constellation had their type certification revoked after in-service accidents.
