An aircraft registration is an alpha-numeric string marked prominently on the exterior surface of all civil aircraft. The aircraft registration code must also appear on the aircraft’s Certificate of Registration. Military aircraft use a slightly different version called a “Tail Number”. When we perform an aircraft rewire for a civil fixed or rotary wing aircraft, we use the Aircraft Registration when we reference the aircraft. When we perform aircraft Kapton rewire on military aircraft, we use the Tail Number when referencing the airplane or helicopter. Visit our page for more details.
