Which organization is responsible for communications search for missing aircraft under the national search and rescue plan?

The organization responsible for communications search for missing aircraft under the national search and rescue plan is the Federal Aviation Administration (FAA). The FAA plays a critical role in ensuring the safety of the airspace and the operation of aircraft. One of its responsibilities includes coordinating search and rescue operations for aircraft that are reported missing.

The national search and rescue plan outlines how various agencies work together during such events, and the FAA is integral to that setup, primarily due to its expertise and authority over civil aviation. While other organizations, such as the National Transportation Safety Board (NTSB), study accidents and provide recommendations, and the Department of Defense (DoD) may become involved in certain instances, the FAA is directly tasked with managing the immediate response to missing aircraft through its air traffic control systems and communication channels. NASA, primarily focused on aerospace research and exploration, does not have a direct role in search and rescue operations for civilian aircraft.
