Unfortunately the NTSB doesn't actually have that power... It's an investigative agency, intended to investigate accidents and make recommendations. Unfortunately, they're just that: recommendations, not mandates. It's up to the agencies that govern the respective industries to issue regulations enforcing those recommendations (i.e., the NHTSA or FAA).
