2.3 Nationality and Registration of Aircraft

The principle — the Chicago Convention's rules: the aircraft has the nationality of the state of registry (the Article 17 family): the aircraft's legal identity — the flag's aviation face. The registration's duties: the single registry (the aircraft registered in one state — the dual registry's bar); the register's maintenance by the state; the nationality-and-registration marks (the "9N" prefix for Nepal — the call-sign's legal face); the registration's conditions (the state's own rules: the ownership-and-operator links — the "genuine link" debates of the flag-of-convenience type). The nationality's consequences: the jurisdiction's anchor (the flag state's law aboard the aircraft — the Tokyo Convention's foundation, Unit 5.2); the responsibility's attribution (the state's oversight of "its" aircraft — the safety-and-security duties); the transfer's discipline (the deregistration-and-re-registration on sale — the Cape Town Convention's financial-interests' face: the aircraft's mortgage-and-lease world). Nepal's practice: the CAAN's register (the "9N" marks); the registration's requirements under the Civil Aviation Act 2053's regime.
