Which regulation was instituted in 1996 to promote 'One Level of Safety' among air carriers?

• A. 14 CFR Part 121
• B. 14 CFR Part 135
• C. 14 CFR Part 119
• D. 14 CFR Part 91

Answer: (C)

The regulation instituted in 1996 to promote 'One Level of Safety' among air carriers is 14 CFR Part 119. This regulation established a unified set of safety requirements that apply to both scheduled and non-scheduled air carriers, regardless of the size or type of operation. By implementing these standards, it ensured that all operators meet the same stringent safety criteria, thus fostering a consistent level of safety across the aviation industry.

Part 119 is significant because it serves as the foundation for the certification process of air carriers and provides essential definitions and requirements related to safety management, operations, and the standards that all carriers must follow. This uniformity helps to maintain public confidence in air travel and ensures that all airlines, whether charter or scheduled, adhere to the same rigorous safety protocols.

In contrast, the other listed parts focus on specific operational issues or categories of aviation that do not directly establish the overarching safety framework meant by 'One Level of Safety.' For example, Part 121 governs the operation of scheduled air carriers, while Part 135 applies to commuter and on-demand operations. Part 91 outlines general operating and flight rules, but none of these regulations promote a unified safety standard across various categories of air carriers to the extent that Part 119 does.
