Police helicopter crashes onto Glasgow pub

Shy Torque:

Your post mirrored my thinking. I remember when I was flying 330’s; the aircraft was on the ground and the engines at ground idle when something sheared on the TR pitch assembly and the tail rotor went to full pitch setting – can’t remember which way. The force was sufficient to yaw the fuselage, even though on the ground at a low power setting.
Many discussions in the crew room on how to cope with that failure in the air – and no positive answer, particularly if the aircraft was at low airspeed at the time.
Only way to stop the yaw is autorotation – and pull collective to slow the NR ……….?
