Part 23 & 25 (FAA regulations)

FAA Part 23 covers certification standards for small aircraft, focusing on safety, design, and performance requirements for general aviation airplanes. It ensures these aircraft meet specific safety criteria before being approved for flight. Part 25 applies to large transport category aircraft, primarily commercial passenger planes, setting rigorous safety, performance, and maintenance standards. Both parts aim to ensure aircraft are designed, built, and maintained to protect passengers and crew, with Part 23 addressing smaller aircraft and Part 25 dedicated to larger, more complex commercial aircraft.
