> Kind of makes you wonder if grandfathering should have a limit (e.g. 50 years?). That's not grandfathering. Grandfathering is "This engine was built before we made the law, so you can keep using it until it breaks."; what you're describing is just blatant selective enforcement.

What’s it called when the thing was designed before the law, and therefore allowed to be manufactured for eternity?

The term "grandfathered" is used in FAA literature for both pre-date (literally) and the designed before a regulation came into being. The reason it exists is otherwise the FAA could release a new requirement that would halt a pre-existing production line that didn't meet it. > Because part 135 operators will have limited ETOPS operations, the FAA has decided to grandfather from today's rule all part 135 airplanes manufactured up to 8 years from the effective date of the rule. For purposes of airworthiness requirements, part 135 operators may use these airplanes in ETOPS without certification under § 25.1535. This is a change from the NPRM, which proposed grandfathering only those airplanes that were on an operator's operations specifications up to 8 years after the rule. Under the NPRM, they would then have had to remain on the operator's operations specifications to continue to operate ETOPS. https://www.federalregister.gov/documents/2007/01/16/07-39/extended-operations-etops-of-multi-engine-airplanes#h-28 https://www.federalregister.gov/documents/2007/01/16/07-39/e... > b.

It means "the aircraft design met applicable requirements at the time it was certified." It's similar to how I can continue to drive an old car that doesn't have ABS, since ABS wasn't required or invented when the car was built. The difference of course is with cars we update the rules and apply them to all new cars as of a certain date. We don't allow someone to keep making cars using a design from 1967, at least not without including current safety features.
