Hello all! Thank you for looking into the issue. I am the the FS2020 and FS2024 user that is looking for the facility in question and had posted on the issue on forums.flightsimulator.com.

SAMI does exsit, is public and is listed in MADHEL data (website, API). It’s local code is STI.
Here is a screenshot from the MADHEL site:
