Does anyone have a FA for a GNC300XL in a Cessna 180 that they could share as data for my install? Our new guy at the FSDO wants more supporting documentation than what come from Garmin.

Thanks

Seen a lot of these installed in various aircraft over the years. It's unfortunate they're asking for a FA. I'm sure the IA's on the forum can speak to this better. Here was the information provided by Garmin for context:

Garmin GNC300 Install Manual: "Consistent with N8110.69 or Order 8110.4, Aviation Authority approved Installers are hereby granted permission to use STC #SA00372WI data to modify your aircraft."

Here is the STC:

Follow up:

My IA pulled together a bunch of documentation to satisfy our PMI, and I installed the 300XL in the 180. Approved and signed off last week. Anyone else interested PM me.
