Title 49 › SUBTITLE VII — AVIATION PROGRAMS › PART A — AIR COMMERCE AND SAFETY › subpart i — general › CHAPTER 401 — GENERAL PROVISIONS › § 40125
Says when a government or military airplane counts as a "public aircraft." It gives short definitions: "commercial purposes" means carrying people or goods for pay (with a few narrow exceptions); "governmental function" means official government work like defense, firefighting, law enforcement, research, or inspections; "qualified non-crewmember" is someone on board who is not crew but is there for military or government duties; "armed forces" means the military as defined in title 10. Government-owned planes do not count as public aircraft if they are used for commercial work or carry someone who is not crew or a qualified non-crewmember. Military planes count as public aircraft if they are flown under title 10, or if they perform government functions under titles 14, 31, 32, or 50 and are not used for commercial purposes, or if they are chartered to provide commercial service to the military and the Secretary of Defense (or the relevant Secretary for the Coast Guard) says the flights are needed in the national interest. National Guard planes only count when they are directly controlled by the Department of Defense. A non‑leased plane used for search and rescue can be treated as a public aircraft only if the FAA finds extraordinary circumstances, the plane will do search and rescue, the community otherwise lacks those services, and a government shows the waiver is needed to avoid an undue economic burden.
