For those that think a recovery from TR failure in such a situation where you are low (<400ft), climbing vertical or backup t/o profile using lots of power is as simple as entering autorotation and guiding the a/c to a landing site then I challenge you to have a go in a realistic sim. Not at 1000ft doing 60 kts in the day. Make it 200ft with 100% torque at night and for realism throw in a 3 second delay. Let me know how you get on.
These types of operations are normal, of course they are. Helicopters fly these profiles in challenging conditions every day so please don't think this was an abnormal operation.
If you are referring to the poorly powered heavy twin 206 that ran out power then it's not the same as a complete TR failure which is a POSSIBLE consideration here.
