The International Cessna 170 Association

I ran across this ad on Craigslist and figured that someone on this forum could use these parts. I have no affiliation or interest in this listing, just passing it on for whoever needs this. There are three horizontal stabilizers in the photo. The seller lists them as applicable to the 170, L-19, an...

Thank you sincerely, I truly appreciate it !

George thank you for checking the previous owner's records, I do appreciate it. AKClimber, I have no desire to circumvent the FAA weight and balance process at all. Weight and balance is both theory and reality. As one of the early competitors experimenting with a tail ballast water tank (contest sa...

Why don't you just get a bunch of real aircraft weight and balance numbers (EW and arm) and then run a computer simulation with different loadings at gross within the flight envelope and some outside of it. You will have to use simple vector math to convert the level attitude to 3 point so you'll n...

Can someone who has done extensive weight and balance work on a 170B assist me with this info request, thanks sincerely in advance. I need to do some calculations for a tailwheel spring material selection (172 to 170 conversion project). As part of my Fravel STC conversion upgrade, I will be going f...

I don't want to overstay my welcome or get too wrapped up on one point. I've received several informative replies and learned things I didn't know. Mission accomplished. I may be able to make a Lady Leg that is close enough to interest 170 owners, or I may only be able to make a gear leg for the 172...

The reason there is such a process is to ascertain the capability of, and enforce the quality of production of, an aftermarket supplier/manufacturer of IDENTICAL replacement parts.... Not "similar"...not "alike'... but IDENTICAL. If your product is not IDENTICAL...in form, fit, funct...

I can't even begin to immagine that there will EVER be a market for anywhere near the number of C-170 landing gear leg units that would have to be sold in order for production to be economically viable. What with owners of C-170s converting to C-180 legs and all of the C-180s in the registry, why n...

A buddy of mine, whose 1952 C-170B I instruct in, is contemplating a C-175 taildragger project, using the Stoots STC. He would specify it be built with the PPONK gear box parts and 180 gear legs from the start. If using new Cessna parts adds a significant value to the project in the mind of the air...

Possibly wrong but, the wedges are in contact and hold the gear firmly in place in the vertical plane as the ground loads would be transmitted through the vertical plane. Any movement here would cause fretting, wear, and ultimately dissimilar corrosion which can ruin an aluminum extrusion in short ...

(Tongue-in-cheek-jest) ...So..... by buying genuine Cessna....we are supporting a lot of fellow Americans? :wink: (Back to more serious response)... If Cessna charges you only $500 for the real-deal engineering dwgs.... Isn't that actually the best, most effective money you could spend to develop a...

I am curious as to what your thoughts are regarding why you believe you can produce a gear better and cheaper than Cessna, considering that you've expressed your opinion they've already been producing thousands of them in the same material you presumeably expect to use to produce only a few. What a...

Thanks for the replies. I have indeed spoken with Tom, he's very knowledgeable, and we are trying to work together if possible. But in the interim, I'm also wanting to solicit additional opinions here. I'm sure there are several highly experienced people specifically with the 170 here. Titanium is n...

In studying the 180 landing gear box parts I got from a junkyard in Canada, and after researching a few steel landing gear failure analysis papers, I have three questions or for the forum experts... thanks in advance. Your assistance will result in more/better/cheaper PMA replacement parts in the fi...

I'm pretty sure that the 170 Association would see a win-win even if the Fravel parts (or whatever I have to change on them to make it simpler) will not be use-able on existing 170's. I'm definitely not a 170 expert or "good ol' boy" by any means. But I'm fairly confident that there are do...
