Once again Dougal Watson, Aeromed-List editor puts us on track on this interesting report  from the NTSB :  «An accident involving a single-engine, turbine-powered, amphibious float-equipped de Havilland DHC-3T airplane, which impacted mountainous, tree-covered terrain about 10 nautical miles northeast of Aleknagik, Alaska. Among the safety issues discussed  inadequate FAA guidance related to the medical certification of pilots who have had a cerebrovascular event, and the lack of passenger briefings related to survival and communications equipment.


      Highly advisable to read whole report and specially pdf-pages #19-23, 55-56, 65-68 and 73-75 as well as conclusions
