Sorry PPRUNE FAN#1 but I am confused!
You start by saying - "LTE had nothing to do with this accident"
Then say - "TR RPM are now so low that directional control is lost"
What is the difference between LTE and loss of directional control due to low RPM?
I have no problem with Bell products and used to fly the 206 series quite happily (and would again if asked!) but I can't see any major difference between your understanding of the event and that of others!
