Published: 08/31/2016

Federal Aviation Regulations (FARs) or 14 CFR Part 25

(n): Title 14, Chapter 1, Subchapter C, and Part 25 of the Code of Federal Regulations (CFR), which is the codification of the general and permanent rules published in the Federal Register by the departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation.1

Did you know that every part on a commercial airplane has to be certified to be deemed airworthy by the U.S. Federal Government in order for it to be installed on the aircraft and flown within the United States? 14 CFR Part 25 is the part of the Federal Aviation Regulation (FARs) that specifies the standards for airworthiness, specifically within the transport category. There are many subparts to the regulation to address all sections of planes in the transport category. Transport category airplanes are defined as jets weighing over 12,500 lbs with more than 10 seats, as well as propeller-driven airplanes weighing over 19,000 lbs with more than 19 seats. Aerospace equipment and component manufacturers within the transport category must abide by these regulations in order for their products to be allowed in flight.
