If that is true....then there must have been something that happened to sever the mechanical linkage for the Collective.....arcing from a chafed wired bundle.....fire?
If you lose collective control....two ways of changing the amount of lift being produced.....speed or Nr.....or perhaps as in this incident....speed and Nr.
That would be some fire to burn through a 4 inch carbon torque tube behind the pilots seats, and in the ceiling. The other control linkages are in the left hand wall behind the LH pilot door. No real wiring in there at all.
When they say "reaction from the rotor system", I'm wondering if they mean RPM control rather than directional control. Otherwise how did they auto it as they did in the video?
Speaking of the video, I don't know if there is a clearer copy somewhere but the maingear doesn't look to be fully extended.
PR ram looks like it hasn't worked. But it is VERY hard to tell from the grainy video.
