Mick, the report doesn't say the engines were "operative". It just says that the cores were rotating at impact but they don't indicate at what possible speeds. Ram airflow will spin the core of a PT6. All that highlights is for example it hadn't seized up/disintegrated etc.
State of the fuel system cannot really be figured out directly from the information at hand. I'm sure they'll investigate what components they can, and if it was refuelled locally I'd imagine they'd already have copies of the delivery docket and samples from the truck.[/QUOTE]
Two men say they Jesus one of them must be wrong.
Ppruners say prop speed between 1586 and 2000 rpm. For this the engine must be running.
Slash marks indication show prop not in feathered position.
Prop will feather with no oil Px from the cold section.
Ram air will not supply enough oil to hold the prop in fine without oil the cold section working.
So is the fuel system working or not.
