The NTSB openly defines transportation investigations as accidents. The entire purpose of the agency existing is to issue recommendations based on the root cause for transportation accidents to prevent the same thing from happening in the future. Any foreign transportation safety agency counterpart in the world has the exact same definition. Whoever the “people who study the problem space” are it sounds like they are trying to twist language for their own personal beliefs and not really studying the problem at all.
