TW 514, to any pilot in the US that remembers it, was one of the real influential accidents--it changed aviation. GPWS and EGPWS comes directly from that accident, as does a slew of FAA ATC changes, radar low altitude warnings and CRM. As I remember it, the FE was on the tape protesting the pilots decision to descend to the intermediate altitude when cleared by Approach Control.
Alas, he didn't really protest, rather he questioned the altitudes on an IAP chart that did not meet U.S. chartings specifications (which required that the intermediate fix be in the profile view.)
I knew the captain quite well. <sigh> And, I was an ALPA rep on that seeming never-ending investigation.
You're right, that accident was a "deal changer," which included ICAO as well as the U.S. But, 35 years has passed so the wheel will likely be invented again, so to speak.
