Aviation Glossary :: Part 25  Aviation Glossary :: Part 25 FAA Written Test Preparation
Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

Part 25
Part 25
CFR 14 Part 25 is a section (Part) of the USA/FAA Federal Aviation Regulations (FARs) that deals with Airworthiness Standards: Transport Category Airplanes.

This part contains airworthiness standards for airplanes in the transport category.

Transport category airplanes are either:

  • Jets with 10 or more seats or a maximum takeoff weight (MTOW) greater than 12,500 pounds (5,670 kg); or
  • Propeller-driven airplanes with greater than 19 seats or a MTOW greater than 19,000 pounds (8,618 kg).

The Boeing 737 and later types, and Airbus A300 series, are well-known airplane types that were certificated to FAR Part 25.

Most of the Federal Aviation Regulations, including Part 25, commenced on February 1, 1965. Prior to that date, airworthiness standards for airplanes in the transport category were promulgated in Part 4b of the US Civil Air Regulations. The Boeing 707 and 727 are two well-known airplane types that were certificated to CAR Part 4b.
