People seem to get worked up about the change product rule and "grandfathering". Rest assured that all of the fuselage and wing are reanalyzed for new loads.
If these calculations were carried out then one would have been able to certify properly according to the current state of the art.
let's be clear: the "grandfathering" system should save manufacturers money in the manufacture of aircraft.
the alleged safety of a system that often functions perfectly for decades is used as an excuse.
it's an excuse, nothing more.
with the "grandfathering" technical development in aircraft construction is frozen. as well as security regulations.
everyone knows that a current 737 would have no chance of being certified according to current standards (emergency exits, breakage, etc.)
with the grandfathering the last cent of profit is pressed out of the frame
this is not in the sense of the people flying in these planes. not in the sense of the crew and not in the sense of the passengers.
the current pickle forke problem will probably be a batch problem otherwise it would have been discovered for a long time at the test beds
