Shackle wrote:aftCG- I went through a similar struggle when trying to do the same thing to my Decathlon and ended up going right to the factory with the question. They have been very helpful and I'm glad I did. Here's what the ACA engineer says:

"There are two options for installation of the 8.50x6 tires. The first option is to keep wheels, brakes, and axles you have - ACA drawings 7-1307 and AC-1511 (if you have aluminum gear use drawing 7-1559). The second option is to install wheels, double puck brakes, and axles used for the Scout - ACA drawing 4-2042.

Both drawings are approved for the 8KCAB. With drawing 7-1307 a logbook entry and updated weight and balance would be sufficient. If you are adding the 4-2042 wheels and brakes - you should fill out a 337 documenting installation to the approved drawing. In both instances you should have the drawing for future reference."

I would assume if the Decathlon is supported than the Citabria definitely would be. The drawing are $50/each from ACA.

I have a 7ECA here and the owner wants to put the Desser tires on legally. Previous mechanic put them on but no paperwork. issues with brake calipers rubing the tires. Haven't checked on the availability of the STC SA3019WE or the instructions for it. Googled and and found this thread. Any help getting these installed both correcctly and legally would be greatly appreciated.

Also, I thinking in that drawing, calls for adding a wheel/ rotor spacer for the 8.00 and 8.50 tires.

FWIW I have the North Sound Aviation STC for my C180 that approves 850x6 tires.
Unfortunately it mandates 6 ply tires--
the Desser smoothies are 4 ply so are not applicable.
Not sure if the Kenmore 850 STC, or anyone else's stc's for 850's on anything, specify ply ratings or not.

Svenn's Aviation holds a lot of STC's for Pacers, including 850x6 tires.
I'm sure there are other, relatively unknown STC's for other airplanes out there.

It's still possible to get a field approval--
unfortunately more possible in some places than others.
Although it took 11 months,
I finally got a FA for 26" GY's on my 180 from the Seattle FSDO about a year ago.
