Global, I have to respectfully disagree. I first became a DER in 1988, and I've watched the evolution of the regulations over the last 28 years.
The regulatory changes that materially contribute to safety are by far the exception. 90% of the changes do little or nothing to improve safety - but increase the aircraft costs and complexity immensely. SEVERAL CHANGES HAVE ACTUALLY HAD AN ADVERSE AFFECT ON SAFETY!
The Feds also have a bad habit of latching onto a relatively minor aspect of the design, forcing the airframers to expend enormous cost and effort to show compliance when the associated failure is fairly benign, while glossing over areas that have resulted in fatal accidents.
I'm glad I'm getting out of it (I'm retiring from Boeing next month).
