SA122NW STC info needed C175

[Eduardo Gueiros]

We recently acquired a 175 TW conversion with a 0-470 (SA122NW STC). While we have the STC document itself, the plane as no updated performance charts based on the new engine.

I know that the STC belongs to Park Robert M, but read in several forums it's basically not possible contacting the guy.

Anyone has any lead on where/who I could possibly contact for information about it?

Thank you!

I know that the STC belongs to Park Robert M,

The current STC revision shows the following holder. STCs get sold/transferred all the time so its best to always check the latest versions on the FAA website. And since you have the STC installed they are required to supply certain documents. Contact the person listed below and include the particulars of your installation and see what happens. If no response there is a route to obtain the necessary documents you need via the FAA. But you have to show your contacts with the current STC holder failed.
