Which regulation governs the air safety of civil aviation in the U.S.?

• A. 14 CFR Part 121
• B. 14 CFR Part 91
• C. 14 CFR Part 135
• D. 14 CFR Part 141

Answer: (A)

The regulation that governs the air safety of civil aviation in the U.S. is 14 CFR Part 121. This specific part lays out safety regulations for the operation of large transport-category airplanes. It is primarily applicable to scheduled air carriers and covers a wide range of safety-related aspects, including the operational and maintenance requirements for commercial air transportation.

By establishing detailed regulations under Part 121, the Federal Aviation Administration (FAA) ensures that commercial operations meet rigorous safety standards, thus contributing to the overall safety of civil aviation. This includes regulations regarding crew training, aircraft maintenance, operational procedures, and reporting of accidents or incidents, all of which are essential for protecting passengers and ensuring safe operations.

In contrast, the other parts mentioned serve different purposes. Part 91 governs general operating and flight rules applicable to all civil aviation operations, but it is not specific to commercial air carriers. Part 135 pertains to commuter and on-demand operations, covering operators that conduct non-scheduled flights, while Part 141 sets standards for pilot schools. Each of these regulations plays a role in the broader framework of aviation safety but does not specifically target large transport air carriers in the same comprehensive way as Part 121.
