There are - and I think people do not realize this - two separate types of "206 LTE." In the first, the t/r simply does not have enough oomph to counter the massive torque to the main rotor. A right yaw rate is allowed to develop which quickly escalates into a worsening situation whereby 'round and 'round you go with your left Gucci loafer pinned firmly to the pedal stop.
But there is another form of LTE that many a OH-58 pilot will describe for you. And that is being at low speed with perhaps a tailwind component and suddenly finding yourself spinning like a top even though the left pedal is not at the limit.
206's have big vertical fins that blank off much of the inflow to the tail rotor. Now put the wind back there at 170 degrees or so, which really aggravates the weathervaning tendency and makes the nose of the ship want to yaw to the right. Throw in some good old-fashioned t/r VRS and you've got a recipe for a nice little surprise. The "break" is so sharp that you might be forgiven for thinking that the t/r has just stalled like the wing of a plank. Happened to me in a 206L-1, and that is what I thought. It felt like a tail rotor failure.
However, Bell's attitude is that the tail rotor is not in fact "stalled" and is still producing thrust - just not enough of it at the moment. Their suggestion is to push and hold full left pedal, reduce power/torque, increase airspeed and "fly out of it." To us old-timers, this is "classic" LTE. Most of us don't have much experience with other types of LTE (especially when the wind is off our left) because we're good about not letting yaw rates develop in the first place. But that LTE-when-the-wind-is-up-your-bum...oh boy, that can bite without warning!
