Dave, (to further the thread drift) That is a gorgeous looking tug. Is it faster enough that you could use it to pull the plane down past the 90 degree turns? Then one person could run it back to the hangar while the other is pre-flighting.

(I've started to think that passenger jets should do that from the gate. Get the tug to get them to the taxiway just prior to runway. Then the sit and do engine start as the congo line feeds departures. There's got to be a fuel price where that starts to make sense.)

That was proposed for airliners a few years ago, would save tons of fuel.

Hi Shawn, Just a FYI on the cost of R134a... a 30# tank cost $90.00 US.. I'm not sure how much your system hold but I would guess no more than 10#...also the refrigerant that was originally in the system should be reclaimed and reused.
It does not go bad (unless it became contaminated..but that would be a separate issue..) or weaken or lose any effectiveness. So really the $500 was labor..

I also must ask... Why does the refrigerant have to be removed for the annual ? does the unit need to be moved for access to something ? Is there something in the Regs ? And did anyone else have this issue ?? Thanks

I had my annual in the DA40 with cabin cool a/c. All that was done was a leak test, filter change, and mounting bracket check. It wasn’t $500.

My annual was completed between the Diamond Aircraft Factory in London Ontario and XU Aviation (also at the CYXU) in summer 2018. I was told that a PROPER annual requires removing a part of the A/C which in-tun requires discharging the system for a proper inspection. This came from the factory not XU. The factory completed that part of the annual and XU completed the rest. My invoice from the factory portion of my bill showed $500 Canadian (before taxes) for A/C Refrigerant recharge. This does not include the inspection portion of the annual completed by the factory! All in all I love my Cabin Cool system and as mentioned before my airplane was the first to have the revised STC controller
