> Fixing the wiring issue would mean fixing it on every single 737 in service, not just the 737 MAX. No it wouldn't as 737 was certified before the new regulation. It is in the article: > That earlier 737 NG model didn’t have to meet the current wiring-separation standards because they came into force long after that jet was certified. Just like with cars - you can drive a car from 70ties without airbags or crumple zones but you cannot buy a new car without airbags as it won't be able to pass the latest regulations. Imo in this case the main issue is not the safety (seeing how the older planes aren't falling out of the sky) but setting a precedent where the certification authority has missed an issue which is not according to regulation - do the manufacturer gets a free pass or it is their responsibility to make the item according to regulation in the first place and it doesn't matter if it was missed during the certification process.

> No it wouldn't I know the previous 737 models were grandfathered. What I am questioning is the argument that, even though we accept this wiring flaw on all grandfathered 737s, it must be fixed on the 737 MAX just because Boeing made a different mistake (MCAS) on the 737 MAX. (If they hadn't made the MCAS mistake, the FAA wouldn't be reviewing the certification of the MAX and wouldn't have found the wiring issue.) > setting a precedent where the certification authority has missed an issue which is not according to regulation Is this the first time the FAA has missed a certification issue? I don't know, but I doubt it. If the FAA has missed certification issues before, has the manufacturer always been forced to rework all affected aircraft when the missed issue is discovered? Again, I don't know, but I doubt it. In any case, these certainly seem like relevant questions to ask before coming to a conclusion.
