Thanks for the input, but with respect, a Saab Donk is hardly a PT6A which is a tiny turbine. I have seen PT6A-20, 27 and 34's all held during start and at idle. They were bear hugged buy a normal size man, seen done many times, hundred of times actually, the management only wanted to hear the engineers who told them what they wanted to hear, although, the better engineers in my opinion, were disgusted with the practice and all insisted it would cost them massively in the long run. I quit that gong show and so did my other friends, so I don t really know if it lead to PT issues later, sorry.
