    Default STC for a C90 in a PA17 Vagabond

    A friend of mine is in the process of rebuilding a PA17 Vagabond with a C90 engine.
    His inspector wants to see a copy of the relevant STC, but my friend has lost it during a recent PC upgrade to Win 8!
    Would anyone happen to have a copy?

    I have tried searching for "STC" but search won't work on 3 letter searches.

    Thanks

    Hi Tony,

    To my knowledge there is no STC for different engines in the Vagabond.

    My A-75 was done on a Transport Canada "Major Mod" and most C-85, C-90, and O-200 installs in the US are done on 337 field approvals.

    If I am mistaken, and any STC paperwork exists for other engines, I would very much like to have a copy. I have a C-85 I would like to put in my PA-17, but I am concerned about the paperwork.

    Thank you,

    Joel

    Joel (Tony),
    I believe Joel is correct in that STCs for engine upgrades to our Vags are non-existent, but pre-1955 Field Approvals do exist and are just like STCs. While I've not seen any pre-1955 337s for C90 installations, Andy Anderson's web site, Short Wing Info, does have a pre-1955 337 for a C85-12 installation. Don't be concerned by the "adult site" warning as it's a google website, and it's quite the Short Wing site full of VERY useful information.
    As such, if you have any pre-1955 Field Approvals for our aircraft types, we would all appreciate it if you would scan/send copies to Steve and/or Andy. We all need to work together to keep 'em flying.
    Best of luck in your search!

    Joel/Curt,

    Thanks for the replies.
    Various Vagabond owning friends over here do believe that there was an original STC (now lost!), but perhaps they were 337s after all.

    I will keep looking!

    Not a C-90, but a C-85 upgrade.
    Late to the party. Sorry, I just saw the post.
    There is a 337 dated 12/11/1954 on PA-17 N4582.
    I can send a screen shot of the log entry if it will help.

    Hope it helps someone.
