State of Registry roles and responsibilities (Article 12 of the Convention)
Each contracting State undertakes to adopt measures to insure that every aircraft flying over and maneuvering within its territory and that every aircraft carrying its nationality mark, wherever such aircraft may be, shall comply with the rules and regulations relating to the flight and maneuver of aircraft there in force.
» Each contracting State undertakes to keep its own regulations in these respects uniform, to the greatest extent, with those established from time to time under this Convention.
» Develops and promulgates regulations:
» Registration of aircraft
» Airworthiness and continuing airworthiness of aircraft
» Noise certification
» Issuance, validation, or acceptance of type certificates
» Issues certificates and permits:
» Certificate of Registration
» Certificate of Airworthiness
» Noise certificate
» Special flight permit
» Export Certificate of Airworthiness
» Approves
o Modification and repair
o Maintenance Organizations
o Maintenance programme
» Ensures the continuing airworthiness of aircraft
o Conducts surveillance
o Take appropriate enforcement action, when required.
o Ensure that it informs the State of Design when it first enters on its register an aircraft of a particular type b. Determine the continuing airworthiness of an aircraft in relation to the appropriate airworthiness requirements.
o Develop or adopt requirements to ensure the continuing airworthiness of aircraft during its service life including requirements that the aircraft:
o Continues to comply with the appropriate airworthiness requirements after a modification, repair, or installation of a replacement part.
o Is maintained in an airworthy condition and in compliance with maintenance requirements of Annex 6.
» Upon receipt of MCAI from the State of Design adopt directly or assess the information received and take appropriate action.
» Ensure the transmission to the State of Design all MCAI issued by the State of Registry in respect of a product or modification originated from that aircraft.
» Ensure there exist a system whereby information on faults, malfunctions, defects, and other occurrences that might cause adverse effects on continuing airworthiness is transmitted to the type design organization. If this is a modification, then the organization responsible for the design modification should be informed.
Each Contracting State should establish
In respect of large aircraft, the type of service information that is to be reported to its airworthiness authority by operators, organizations responsible for type design, and maintenance organizations. Procedures for reporting this information should also be established.
» Part III of Doc 9760 Certificate of Airworthiness State of Registry has to ensure that the design of the aircraft meets the appropriate airworthiness requirements.
» This can be done through:
o Type Certification - Full certification exercise
o Type Validation - certification review to the differences that exist between the State of Registry and State of Design
o Type Acceptance - recognition and direct acceptance of type certification already done by the State of Design
Maintenance program
An approved maintenance program is required for each aircraft type. The information in a maintenance program should contain at least the following:
» Maintenance tasks and the intervals at which these are to be performed
» When applicable, a continuing structural integrity program
» Procedures for changing and deviating from the above
