What entity primarily regulates commercial aviation safety in the United States?

The Federal Aviation Administration (FAA) is the primary entity responsible for regulating commercial aviation safety in the United States. Established within the U.S. Department of Transportation, the FAA's mission encompasses creating and enforcing regulations that ensure the safety of civil aviation. This includes overseeing aircraft operation standards, pilot licensing, maintenance practices, and the overall safety of aviation operations across the nation.

The FAA's broad scope of authority allows it to set safety and operational regulations that all commercial airlines and aviation stakeholders are required to follow. This regulatory framework is critical for maintaining high safety standards within the aviation industry, as it encompasses both airspace management and the certification of aircraft and personnel.

Understanding the FAA's role is paramount for anyone studying air law, as it directly impacts not just commercial airlines but also general aviation and air traffic control, forming the backbone of a safe and efficient aviation system in the U.S.
