My question is to the shutdown feathering of the Engines, I understand normally Garetts aren’t feathered on shutdown but why was there smoke and flames on feathering this time? Did they forget to shut off the fuel first and it melted down? (A little like on the old F-27 ( RR Dart fixed turbine ) if you didn’t engage the prop locks after landing it would quickly over temp and melt down…)

just curious.
Looks a lot like the by product of pulling the stop and feather/emergency stop function on a Garrett. The engine doesn't have the chance to purge the combustion chamber, so a fair bit of unburnt fuel I'd suggest from my very basic, engine goes brum brum level of knowledge. Happy to stand corrected.
