Which regulatory body oversees ATP Instructor certification?

The Federal Aviation Administration (FAA) is the regulatory body responsible for overseeing ATP Instructor certification in the United States. The FAA establishes the standards and regulations for aviation, including flight training, instructor qualifications, and certification processes. This body ensures that all flight instructors, including those seeking ATP certification, meet the necessary qualifications and comply with federal regulations regarding aviation safety and training protocols.

The other mentioned organizations, while involved in various aspects of aviation, do not directly oversee the certification of flight instructors. The NTSB primarily focuses on investigating aviation accidents and ensuring safety, ICAO sets international aviation standards and regulations but does not have authority over individual instructor certifications, and the DOT encompasses broader transportation policies, which include but are not limited to aviation. Hence, the FAA is the correct authority in this context.
