The Beech Bonanza (A36) and the CT4B Airtrainer also have the interconnect. Interestingly, the CT4A Airtrainer (as supplied to the RAAF) does not have the interconnect.
There was some extensive "discussion"and testing at ARDU of the CT4A with the 'report' highlighting control line breakout forces in the rudder system as being of 'concern'.
When the CT4B was being (re)certified in NZ for Australian use, the bandaid fix for a perceived problem by an ex Farnborough bright spark (not a pilot) was to fit an airleron/rudder interconnect. What a dog to fly aero's in, what a tiresome dog to fly in formation.
