Ok here is my 2 cents worth.
If you have a full blown TR drive failure you are going to be in "Immmediate Actions" mode and will most likely have to enter full Autorotation ( engines off ). This will severely impact your options. Best or luck!
If you are dealing with loss of tail rotor control or stuck pedals ...things are looking up.
If the aircraft is controlable ....
Slow to 80 knots in level flight. Look at the Ball...is it off to the left or right? Go to the opposite side then ..Lucky Left- Rotten Right . ( basically ball to the LEFT = rotten right, Ball to the Right = Lucky Left.) NB. The further the Ball is out..the worse your problem is.
If Lucky Left you will be able to land with higher torque perhaps even bring it to the hover. Rotten Right landing will be at a lower torque and run on will be required.
(Oh this is for North American machines, EU folks use "Lousy Left ...Righteous Right)
Truck on back to your "suitable forced landing area".
Set up an normal approach starting at 80 knots initialy with a 2-300fpm descent rate ( use cross wind to your best advantage. Left xwind for Rotten Right..Right xwind for lucky left.)
Slow down but keep it at a speed/ torque setting that keeps the nose aligned with the runway.
At the slowest possible speed land be prepared to shut down engines if Rotten Right.

Some smart person wrote a very nice blurb on this with diagrams and it used to be in our OPS Manual.
Worked well. Actually I believe he posts here from time to time. Great training guy and a darn fine pilot.
