RCC, which will plan the search and assign search areas. When
such aircraft are used, the RCC will provide the following
information as quickly as possible to the United States
immigration and customs authorities nearest the search area:
the purpose of the flight and the territory to be searched,
the identification markings of each aircraft, the number and
nationality of the crew of each aircraft, the duration of
stay, and the landing location if a landing is planned. If a
Canadian aircraft lands in the United States, either the RCC
or the aircraft pilot reports to the nearest collector of
customs to assist with any special importation required in the
SAR operation. (1949 Agreement Between Canada and the United
States Respecting Air Search and Rescue Operations, 63 Stat.

3. The SAR Agreement between Chief of Defence Staff, Canadian
Forces and Commandant, USCG, October 25, 1974, provides for
SAR response in certain waters. These waters are adjacent to
ICAO Search and Rescue Regions (SRRs), as well as waters on
either side of the international boundary between Canada and
the United States. In these waters, SAR forces of either
nation may begin or coordinate SAR operations in the maritime
area of the other, when such are required or appropriate.
Each nation keeps the other informed of activities of mutual
interest, or when it may help to ensure continuity of SAR
operations.
B. Mexico. Mexican vessels and aircraft may assist Mexican
vessels and aircraft and their crews and passengers in the following
United States territorial waters or on their shores: within 720 NM of
the international boundary on the Pacific coast, and within 200 NM of
the international boundary on the Coast of the Gulf of Mexico. The
commanding officer, master, or owner must send notice of his action or
intended action to authorities at the port of entry nearest the
distress. Having made this report, the Mexican unit may continue to
assist the distressed vessel or aircraft unless the RCC or other
competent authority determines that adequate assistance is otherwise
available or that assistance is not necessary. Upon departure from the
United States territorial waters, the commanding officer, master, or
owner of the vessel or aircraft must notify the competent authorities of
departure. (1935 Treaty Between Mexico and the United States Relating
to Assistance to or Salvage of Vessels, 49 Stat. 3359, TIAS 905)

country other than Canada or Mexico for SAR operations in the
United States, including the territorial sea, and follow-up
procedures are not otherwise established by prior agreement,

military commander responsible for the defense of the area and
the Department of State. Where overflight of the United
States land areas is involved or landing is planned, the
