Rumour, Innuendo and Hearsay:
I AM NOT A CHINOOK PILOT
I recall an RCAF pilot telling me +- 20 years ago about a failure mode that caused the aircraft to suddenly want to swap ends in forward flight. Can’t recall if it was a CH-46 Labrador or a CH-47 Chinook. It was apparently a fascinating event requiring a change of undergarments and the intervention of a surgical team to remove the seat cushion.
Vaguely recall his explanation as to what caused it but not enough to speculate. It was either a total failure of some system or sensor or a partial failure of same suddenly inputting incorrect swashplate movements. One rotor suddenly wanting to go left and the other right while in stable fwd flight.
A new Emergency Procedure with some highlighted “Immediate Action Memory Items” was created I believe.
I think that there was an similar incident some time ago that was discussed here or on another Aviation site years ago.
