Yes, specifically the Air Comm kit (STC SR00491DE). There is a drive wheel for the AC compressor which is inserted into the drive shaft to the tail rotor. Splined mating face so that power is taken for the AC compressors and the TR continues to turn.
It seems that there can be movement leading to wear, which strips the splines and eventually there is no friction and this stops drive to the TR.
Only on this model, one fix is to remove the AC drive wheel and replace with an Airbus unit. Check the CAA web page. New link below as that last one does not appear to connect.
