Do you even know how to read an AC?

If you could, you would see that the AC addresses several regulations.

2.AUDIENCE. This AC is intended for use by aircraft operators, maintenance organizations,and maintenance personnel when determining the quality, eligibility, and traceability of aeronautical parts and materials intended for installation on U.S. TC’d products and articles, and to enable compliance with the applicable regulations.

5.RELATED CFR PARTS. Title 14 of the Code of Federal Regulations (14 CFR) parts 1, 21,39, 43, 45, 91, 119, 121, 125, 129, 135, and 145.
 
From FAA Order 8300.16A:

10. Commercial Off-the-Shelf (COTS) and Other Articles Not Produced Under § 21.9.

a. COTS Articles. COTS refers to articles that have been developed for sale to the general public. For the purposes of this order, both COTS and articles not produced under § 21.9 are addressed in the same manner. Installation of such articles can be approved but requires an evaluation based on their intended functions and failure modes and effects. In addition, such articles installed for “situational awareness” or as a supplemental system may be acceptable provided they do not interfere with or displace required equipment, or otherwise interfere with the safe operation and airworthiness of the aircraft.

b. Installation of COTS Articles. Section 21.9 was not intended to restrict an owner or operator or their repair and maintenance facility or person from installing “commercially available” articles on their products.

c. Determining the Suitability of an Alteration. A commercially available article (part) does not have to be approved in order for an alteration including that article to be accomplished in accordance with part 43. The installer must determine the suitability of the alteration as follows:

(1) For major alterations, the installation of an article must be performed with approved technical data.

(2) For minor alterations, the installation of an article must be performed with acceptable data.

(3) The approved or acceptable data must show that an article meets the airworthiness requirements and is suitable for its intended purpose.

d. Evaluating an Alteration. The ASI should use the same criteria for evaluating an alteration that includes the installation of an article not requiring FAA approval as that of any other alteration, since the provided data should show that the article is Airworthy. If the ASI has any doubt about the airworthiness of the article, he or she should request assistance from the ACO. The approved or acceptable data for the alteration does not mean the installed article is approved under § 21.9, nor does it mean the article is approved by the installation technical data approval.

e. Return to Service. Maintenance information for the COTS equipment in the form of repair instructions or test specifications will facilitate maintenance and approval for return to service of the original COTS item.

f. Limitations of COTS Articles. The installer and owner/operator should be aware of these limitations associated with installation and maintenance of COTS equipment
 
1. Purpose of This Order. This order provides guidance applicable to the data approval process for major repairs and alterations, including field approvals. The source basis for this order is Title 14 of the Code of Federal Regulations (14 CFR) part 43.

Who can tell me the difference between a order and a regulation ?
 
  • Orders and Notices: FAA orders and notices are issued by the FAA as guidance material for FAA personnel. While FAA personnel are the primary audience for orders/notices, the aviation industry may use orders/notices as reference and the general public may find particular orders/notices of interest. The FAA maintains all of its current and updated orders and notices on a single database.
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviationactivities in the United States. The FARs are part of Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, model rocketlaunches, model aircraft operations, Unmanned Aircraft Systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk.
 
21.9 Replacement and modification articles.
(a) If a person knows, or should know, that a replacement or modification article is reasonably likely to be installed on a type-certificated product, the person may not produce that article unless it is—

(1) Produced under a type certificate;

(2) Produced under an FAA production approval;

(3) A standard part (such as a nut or bolt) manufactured in compliance with a government or established industry specification;

(4) A commercial part as defined in §21.1 of this part;

(5) Produced by an owner or operator for maintaining or altering that owner or operator's product;

Good for you. :)
not tell us what a minor alteration /modification is?
 
I flew my Taylorcraft home once with duct tape holding the wing fabric together after cutting it open to remove bird nests found during an annual... with a ferry permit signed by the IA to make it legal.

We won't mention any other repairs that may or may not have been performed. Nowadays... it sure is nice to be flying an experimental...
