After dealing with the FAA for four years on rouge airport management under Grant Obligations I have zero faith in them for anything. Rather than actually getting off their butts and putting eyeballs on things they sit cozy behind desks and accept scat fed to them by Airport Managers and Operators. If they simply got on an airplane, it is after all the Federal Aviation Administration, and inspected things for themselves it would serve safety and the interests of the tax payers a lot better.
When I lived in Alaska it was obvious that flying there is as different from lower 48 flying as the moon is from earth. The NTSB urging FAA to do something will cost millions, take decades and do little of actual value.
