This is not new....but I did find the Accident Report very interesting reading.
The one thing that sort of jumped off the page at me was the opinion given by the Accident Investigator re simulating an engine failure in the Bell Jet Ranger by "....shutting off the fuel cork......".
Me thinks he means the Fuel Valve Switch.
I can imagine a Check Captain "Switching Off....the Hydraulics" but somehow I think anyone that would shut off the fuel to the engine at 60 Knots and 200 feet AGL over the "Bush".....to simulate an engine failure might just be erring on the side of realism in what should be a training situation.
