Sure that this was a TR drive failure? I saw a longer video of the approach and the TR RPM didn't change during final and beginning of the rotation .
If it wasn’t a driveshaft failure it must have been a hard right pedal input, or control runaway. It’s difficult to tell if the tail rotor rpm changed because we’re not watching in real time and camera frame rate masks what’s going on.

As per the previous post, the aircraft are totally different types (169 versus 109) and their tail rotor control systems are totally different.
