Our goal is to provide STC modification availability, data and research for your GA airplane.


STC-Mod.com is to provide a single location for currently available STC modifications for your general aviation airplane.  There have been thousands of STC modifications developed over the years.  Many of them have been abandoned or are simply no longer offered to the open market.  Our goal is to identify those that ARE available and to get you in touch with the STC mod owner in order to obtain more information and availability to purchase the STC.

This data will also be helpful if your airplane already has an installed STC modification and you are in need of information,  Instructions for Continued Airworthiness (ICA) or other data to cover your airplane. 

If there is information not contained here or if you have information on an STC mod we need to add please let us know through our Contact page.
