Which agency oversees aviation safety and standards in the United States?

The Federal Aviation Administration (FAA) is the correct answer because it is the primary agency responsible for regulating and overseeing all aspects of civil aviation in the United States. This includes the establishment and enforcement of safety standards for both commercial and private aviation, managing air traffic control, certifying pilots and aircraft, and promoting aviation safety measures. The FAA's comprehensive approach to aviation safety encompasses everything from aircraft design and production to the operation of airlines and maintenance protocols.

While the National Transportation Safety Board (NTSB) plays a crucial role in investigating aviation accidents and making safety recommendations, it does not have regulatory oversight or the authority to enforce aviation standards. The Department of Transportation (DOT) is a broader governmental body that encompasses various transportation sectors, including aviation, but it does not focus exclusively on aviation safety. Similarly, the Occupational Safety and Health Administration (OSHA) primarily addresses workplace safety and does not specifically oversee aviation safety or standards. Therefore, the FAA stands out as the authority overseeing aviation safety and standards in the U.S.
