Panel updates 337,STC’s Approved data search

[warrenehc]

Hello,

In working with my mechanic to insure airworthiness after installing GARMIN G3X and GFC 500. You have to secure the panel using the shock mounts unless getting 337 to hard mount the panel back in place. Garmin cannot approve that change with there STC. My avionics shop stated they would still be using the shock mounts.

The next thing was moving the toggle switches on the panel. Per my mechanic, to move the toggles from there current location on the panel one of a few things have to be in place.

1. Mooney drawing showing toggles in different location 

2. New 337 approving

3. Old 337 for model and following those placements

4. STC from shop allowing them to place toggles in new locations 

key word used for all was “APPROVED DATA” 

With that all said does anyone have access to any of this approved data to relocate some toggles on the panel?

I've never heard of such difficulty in moving switches.  If the panel were a structural member, then adding holes and changing the layout might matter, but it is not that for a Mooney.  I think any sensible shop would classify moving switches as a minor mod and just sign it off.  Approved Data is needed for major mods...
