Goodyear Brake MC Parts
Hey guys, I'm a new member. I work for a company that is restoring two 49' Stinson 108-3s.
Have any of you installed the Cleveland brake and wheel kit on a 108-3?
Univair says it's approved but the TCDS calls out only Goodyear brand brakes and wheels for the 108-3.
That's what the STC is for. "Supplemental" type certificate.
You might also look into ABI wheels and brakes.
After the work is finished you should enter the brakes on the weight and ballance, equipment list. That should take care of the type certificate.
Is there an STC for Cleveland wheels and brakes? Our predicament is the Cleveland wheels and brakes are not called out for the 108-3 in the TCDS therefore, they are not approved for the 108-3. They are called out for the 108-1 and 108-2.
Don't be so sure. The faa or Univair does not change a type certificate to please everyone. There are plenty of STC's that don't show up on them.
You can install either Cleveland or Alaska Bush wheels on a -3 with a little homework and an IA.
@jonnysouthwindglobal-com are you looking at a current TCDS? It appears to me under Data Pertinent to all Models items 201(c) and (g), both Cleveland wheel and brakes products, are allowed on a -3.
The answer lies in the TCDS header for the 108-3 "(Same as Model 108-2 except for larger fuel...)" This statement in the TCDS is proclaims these aircraft are essentially identical except as noted. This then makes the use of "Data Pertinent to All Models" approved data. Thus allowing the up-grade to Cleveland brakes. At least that was told me by Univair engineering and was confirmed by my FAA inspector, when I asked this question 30 years ago. The IPC is not "Approved Data" for major alterations but the TCDS is.
They may be mostly identical, but I believe the axles are different, which may or may not affect the brake installation. Also, having the brakes on the TCDS is a luxury. Check for an STC.
Thank you guys!
