Classification of design changes.
(1) A “minor change” to the design of an article produced under a PMA is one that has no appreciable effect on the approval basis.
(2) A “major change” to the design of an article produced under a PMA is any change that is not minor.
Approval of design changes.
(1) Minor changes to the basic design of a PMA may be approved using a method acceptable to the FAA.
(2) The PMA holder must obtain FAA approval of any major change before including it in the design of an article produced under a PMA.

Title 14 published on 2015-01-01
The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 14 CFR Part 21 after this date.
These airworthiness design standards are issued to AutoGyro for certification of the Model Calidus gyroplane under the regulations for primary category aircraft.
The FAA is amending certification procedures and marking requirements for aeronautical products and articles. The amendment requires production approval holders to identify an accountable manager who is responsible for, and has authority over, their production operations and serves as the primary contact with the FAA; allows production approval holders to issue authorized release documents for aircraft engines, propellers, and articles; permits production certificate holders to manufacture and install interface components; requires production approval holders to ensure that each supplier-provided product, article, or service conforms to the production approval holder's requirements and establish a supplier-reporting process for products, articles, or services that have been released from or provided by the supplier and subsequently found not to conform to the production approval holder's requirements; removes the requirement that fixed-pitch wooden propellers be marked using an approved fireproof method; and changes the title of part 21 of title 14 of the Code of Federal Regulations. This amendment updates FAA regulations to reflect the current global aeronautical manufacturing environment, thereby promoting aviation safety.
This notice announces the FAA's intent to designate Silvercraft S.co.p.a. (Silvercraft) Type Certificate (TC) H2EU, issued in the normal category, as abandoned. The FAA has been unable to locate Silvercraft, the TC holder, concerning the continued airworthiness of the aircraft certificated under its TC. The Federal Aviation Regulations (regulations) require that TC holders report certain failures, malfunctions, and defects to the FAA. The regulations also require, upon request, that TC holders submit design changes to the FAA that are necessary to correct any unsafe condition in their products. The FAA is responsible for surveillance of Silvercraft's ability to perform continued operational safety management and oversight of the helicopter on its TC. This action is intended to ensure that Silvercraft Model SH-4 helicopters are under a TC that has active continued operational safety management and oversight by a TC holder that can be subject to periodic safety audits by the FAA.
This notice announces the existence of and requests comments on the proposed airworthiness design standards for acceptance of the AutoGyro Model Calidus gyroplane under the regulations for primary category aircraft.
The FAA is proposing to amend its regulations to adopt specific rules to allow the operation of small unmanned aircraft systems in the National Airspace System. These changes would address the operation of unmanned aircraft systems, certification of their operators, registration, and display of registration markings. The proposed rule would also find that airworthiness certification is not required for small unmanned aircraft system operations that would be subject to this proposed rule. Lastly, the proposed rule would prohibit model aircraft from endangering the safety of the National Airspace System.
