Federal Aviation Regulations Practice Test 2026 – Complete Exam Prep

The correct choice relates to Part 23 of the Federal Aviation Regulations (FAR), which specifically addresses airworthiness standards for normal, utility, acrobatic, and commuter category airplanes. Part 23 sets forth the design and performance requirements that manufacturers must adhere to in order to ensure that aircraft are safe and reliable for flight operations. This part includes specifications for structural integrity, performance capabilities, and operational limitations necessary for certification.

Other parts of the FAR, such as Part 91, concern general operating and flight rules; Part 61 relates to the certification of pilots and flight instructors; and Part 139 deals with certification of airports. While these parts address important aspects of aviation safety and operations, they do not encompass the specific standards related to the structural and performance requirements essential for determining the airworthiness of aircraft, which is exclusively found in Part 23.
