OK Dude, thanks very much for that. Extremely interesting, I assume that there must have been some sort of fuel control failure for a sub-idle N2 to establish with the engine lit.
I've never heard of this phenomenon before, although I know that some fairly odd things can happen in helicopter rotors where the air below the rotor can be pulled around by the passing blades which sounds vaguely similar.
What steps were taken to prevent his happening again? Modification of the fuel control scheduling or something else?
