Which Part of Title 14 of the CFR outlines "Certification Procedures for Products, Articles and Parts"?

The section that outlines "Certification Procedures for Products, Articles and Parts" is located in Part 21 of Title 14 of the Code of Federal Regulations (CFR). This part specifically details the requirements and processes for obtaining certification for various aviation products, such as aircraft, engines, and components. It includes procedures for both the type certification of new designs and the production certification for manufacturing.

Understanding this context is crucial for aviation professionals, as knowledge of the certification processes ensures compliance with federal regulations and contributes to the safety and airworthiness of aircraft. Additionally, being well-versed in Part 21 is essential for those involved in manufacturing, as it lays the groundwork for ensuring that parts and products meet the necessary standards before they can be used in aviation.

Other parts mentioned, such as Part 23, focuses mainly on airworthiness standards for normal, utility, acrobatic, and commuter category airplanes. Part 121 addresses the operating requirements for domestic, flag, and supplemental operations of airlines. Part 145 governs repair stations and their certification. While these parts are important in their own rights, they do not pertain specifically to the certification procedures for products, articles, and parts as outlined in Part 21.
