It would be so great if you could help me...

I understand that Supplement behind the AFM/POH is also approved during Type Certificate process, and since according to 91.9, AFM is legally required to be inside airplane, so that AFM supplement should be inside cockpit as well. I get that,

but i cannot find the legal interpretation that owner should keep the paper copy about their supplemental equipment.
For example, G1000 reference handbook , GNS430/530 guide etc..

if you need info about my airplane by any chance, it's Textron C172S with G1000 ICS

thank you in advance, have a wonderful day :)

You don't need to keep the manuals, just the paper with the STC on it. I keep copies in a transparent folder with the AROW and certificate that I landed at Leadville, CO.
 
Are you asking about having a paper copy as opposed to a digital one or about whether yiu have to have the reference handbook (usually named “Pilot’s Guide”) available? If the latter, you’ll find the answer in the Limitations section of the aircraft or AFMS.
 
Here, for example, is the AFMS for a GTN

And one from the POH if a G36 Bonanza (I didn’t have a Cessna 172 NAVIII POH readily available)

You’re intermixing a couple things here. The AFM/POH and supplements are one item and whether they are paper or digital is a separate item. So is the question whether the supplements are required to be onboard or if those supplements can be paper or digital?

it really helped! but I was looking for legal requirements, but i guess since the poh/afm says to have those in the cockpit, I'll follow that thanks again!

Third question is whether it’s about the AFM/POH/AFMS at all or the Pilot Guides.
 
Paper or digital must be onboard....

FAA (or other regulatory authority) approved Airplane/Rotorcraft Flight Manual Supplements, and any other documents they state in their limitations section(s) are require themselves.

If you’re looking for a reg, how about 91.9?

That would seem to cover it ;)

... no person may operate a civil aircraft without complying with the operating limitations specified in the approved Airplane or Rotorcraft Flight Manual ...​
​
No person may operate a U.S.-registered civil aircraft ... unless there is available in the aircraft a current, approved Airplane or Rotorcraft Flight Manual ...​

@leejy1025, does that work for you for a "legal requirement"?

Key phrase, the interpretation of which is clear.

Unless there is a follow-up memo or letter from FAA because it wasn’t clear, or the intent of the reg when written hadn’t considered the invention and proliferation of our tiny portable electronic devices.

It doesn't say "unless there is available in the aircraft a current, approved Airplane or Rotorcraft Flight Manual in paper form."

Our tiny portable electronic devices are the subject of AC 120-76 (currently Revision E), Authorization for Use of Electronic Flight Bags, for the 91K, 121, 125, and135 people, and AC 91-78 (currently Revision A), Use of Electronic Flight Bags, for us plain vanilla Part 91 folks.

The FAA has actually been pretty good about this stuff, leaving it to the malleable world of guidance documents as opposed to the process of regulation.

I would add AC 120-76E - Authorization for Use of Electronic Flight Bags to the supporting documentation, especially appendix B.
