Cleveland brakes and 8.5-6 tire STC Paperwork
Sorry if all this has been covered before, tried searching but this is my first time using a forum, so I may prove to be a bit inept. I just bought my first plane, a 1952 170b which is in great shape and is currently in annual. The only caveat is that the mechanic is flagging the Cleveland brakes and the 8.50-6 tires because no paperwork has been filed for them, to my understanding a form 337? I called the previous owner and he had no idea, I guess no one had ever flagged it in his annuals, they have been installed for quite some time. I have tried searching and scouring different resources and am quite sure I am just looking in the wrong places. Any advice for this newbie on how to proceed would be greatly appreciated. I imagine someone in this group has some experience with this...

If you are an Association member you can go to the MX Library section of this forum. You will find several discussions of Cleveland wheels and 8.50 x 6 tires and the necessary approvals that are available. Membership has its rewards! Isn't that somebody's advertising slogan?

Re: Cleveland brakes and 8.5-6 tire STC Paperwork
Welcome to the Association and congrats on being a new owner.
There is a very extensive search feature built in to this website. You can easily search for any subject such as 8.50-6 tires and get lots of hits.
To help you get started, click on the link below and you’ll see there is no STC but the FAA has addressed this issue. Many folks have taken this letter as approval from the FAA. Some of the wording is awkward but the intent is to say 8.50-6 tires on proper wheels is approved. It says “original” wheels but if you have STC’d Clevelands, that should be good enough. Hope this works for you.

(Edit: It appears Bill and Richard and I were all typing replies at the same time)
They are separate yet co-dependent issues. First you’ll need to find an approval basis for the brakes. Then find an approval basis for the tires. Then find an approval basis for the brakes with THOSE tires (and hoping that the actual wheels, brake-part numbers are consistent with the approval basis found.)
Parker Hannifin/Cleveland sells/sold an STC approving certain wheels and brake parts on the airplane. Those wheels/brakes may or may not be approved in conjunction with those tires.
It is possible that someone went to a salvage yard, found a group of parts they could fit onto your airplane and did so and no approval basis was ever provided for the combination. (It’s also possible that McCauley wheels/brakes are being mistaken for Clevelands ...but that’s another complicating possibility we’ll ignore for now.)
If you go to our MX Library and download the copy of the STC there and then confirm the parts listing in that STC is what is presently installed then you’ll be on your way to satisfying matters. Then treat the tire installation as a separate matter, keeping in mind that the STC likely did not mention those 8:50 tires and you may have to find a different approval basis for the tires if you insist on keeping them. (Or you may choose to install tires which are acceptable for simplicity sake.)
That is my short-version of the task before you. I’ll spend some more time on some research (as will others I am sure) and hopefully help shorten the task.

Welcome to the forum!
This post explains why you don’t even need an STC to install 40-97A Cleveland wheel assemblies and 30-63A brakes.

Re: Cleveland brakes and 8.5-6 tire STC Paperwork
Thanks so much for the responses guys! I had a feeling the questions had been answered many times before just wasn't sure where/how to look. Im slowly learning how the forum works and hopefully won't post many questions that have already been answered in the future! Seems like a great group of people in the association, look forward to getting more involved and hopefully one day I'll be able to actually answer questions. These answers have been immensely helpful, hopefully with this I can get my plane out of "Annual Jail".
Thanks again.
Caleb
Thanks again.
