What is Part 25?
Part 25 is a section of the Code of Federal Regulations (CFRs) that specify the
design requirements for transport category airplanes.* These requirements are
known as airworthiness standards and ensure that any transport aircraft design
approved by the FAA can be operated safely. This FAA design approval process is
known as “certification”
*Note: In the CFRs, “airplane” means a heavier-than-air, fixed wing aircraft.
“Rotorcraf” means a heavier-then-air aircraft that uses one or more rotary wings
for flight; a helicopter is a kind of rotorcraft. The term “aircraft” includes both
airplanes and rotorcraft.
What is Aircraft Certification?
Certification is the FAA’s process to evaluate, conduct flight test, and approve a
proposed aircraft design. This process assures safe aircraft designs. FAA
certification results in a formal document called a Type Certificate
