After reading the “PDF” it sounds like the NTSB is trying to get the FAA to play “nice” with the Alaska operators. I visited Anchorage this past summer and the aviation museum there actually has a display on how the Washington DC government in the 1920’s came down with a heavy hand on operators and how well that was (not) received. Maybe if more of the Washington FAA bureaucrats (including the administrator) would spend more actual time in Alaska, not just a weekend visit, they might realize that a lot of lower 48 standards just won’t work in the unique environment that is Alaska.
My wife and I did take an air tour of Denali from an operator in Talkeena in a turbine Otter and enjoyed every minute of that ride. The pilot was very professional, not doing any hard turns or “g” loading or any other abrupt maneuvering. The trip had been originally included a climb over the top of Mt Denali and a landing on a glacier. We had to take a different trip due to weather making the previously mentioned items not possible. Hopefully the actions of this operator rubs off on others there so the accident numbers in Alaska do go down.
