Which regulatory body oversees repair stations in the United States?

The Federal Aviation Administration (FAA) is responsible for the oversight of repair stations in the United States. This regulatory body establishes the standards and regulations that ensure the safety and proper maintenance of aircraft. The FAA sets forth the certification requirements for repair stations, ensuring they adhere to strict guidelines regarding personnel qualifications, maintenance procedures, and safety practices.

The role of the FAA is crucial in maintaining the overall safety of civil aviation, which includes regular inspections and enforcement of compliance with federal regulations. The other organizations mentioned, such as the National Transportation Safety Board (NTSB), focus on accident investigations and safety recommendations rather than direct oversight of repair facilities. The International Civil Aviation Organization (ICAO) is involved in setting international aviation standards but does not operate at the local level in the U.S. Air Traffic Control, while essential for managing air traffic, does not engage in the oversight of aircraft maintenance or repair stations. Hence, the FAA's specific function in regulating and inspecting repair stations distinctly highlights its role as the correct answer.
