GB, I think you are correct.
IIRC, several years ago there was a classic HF incident in Canada when for a chain of reasons, a B206 was wheeled out for gd runs/hover check after major maintenance. The Jesus nut had been left on the bench. Everything OK at ground idle, but, on wind up to flight idle, (and perhaps a little collective), the rotor departed the airframe. This was inconvenient,...... but the engine, relieved of its load, went to nose-bleed RPM on the N2 train. Result - welded PT wheels to the labyrinth seals on the casing. Only the Lord knows how many RPM, but certainly exceeded the plastic deformation of the wheels' constituent steel. This just for info - VFR
