Bendix Wheels and Brakes STC options

[at7615]

Got Bendix 40-113 wheels and 30-75 calipers field approved on a 50 Pacer with wide gear and STC SA11RM for the 1.5 axles. Is there an STC for these wheels and calipers on a PA-22/20? My research indicates these wheels and calipers are cessna PN's.

Bendix or Cleveland? These part numbers don't ring a bell pertaining to Pipers to me.

My bad, Cleveland.

I have a customer with the same setup. It was done in 1981 but no 337 was processed. He has the old 1981 version of the "Light Plane Components" STC SA12RN wide gear conversion and they used the 30-75 Brake and 40-113 Wheel but he never did any 337 paperwork on the mod. I am trying to get it sorted out and am looking for several things:

1 - A copy of the "Light Plane Components" installation instructions for their wide gear with 1 1/2" axles.

2 - Any approvals or copies of 80's and newer field approvals using the 30-75 Brake & 40-113 Wheel with these wide gear.

3 - Any closeup detailed photos of this conversion as installed on an early PA-20.

Thanks,

Wes, have you called Univair?

Hello Steve,

No I have not. The owner has. His only avenue with Univair is to buy a copy of STC SA12RN. The 30-75A brake and 40-113 wheel have no known STC's for their installation on any of the PA-20 gear legs.

I am also trying to figure out if the 2 Goodyear 572046 master cylinders are the correct cylinders for the 1950 PA-20.

The Pacer used Electro master cylinders and expander tube brakes. Sounds like you need a field approval for the wheels and brakes and master cylinders or use AC 23-27. https://www.faa.gov/regulations_poli...mentID/1021446

Have you any idea what these goodyear cylinders came out of? So far I have not found much useable with Google.
