I have a few machines with the Aircomm aircon but only one affected as the aircon was recently installed. It seems like Aircomm changed the drive flange from being a seperate splined drive infront of the rotorbrake disc driving the belt to a integrated unit which is now behind the rotorbrake disc and is the flange driving the Tail Driveshaft as well. Why did they change? Surely they can go back to the original STC fit which will solve this immediately?
We will be disabling the compressor and replacing the Aircomm unit with the Airbus flange as 25hrs is 4-5 days flying ap the AD./
