3.4 Airworthiness inspection division responsibilities
3.4.1 In all States it will be necessary to establish some form of airworthiness inspection organization to meet the requirements set forth in the Convention and in Annexes 6 and 8. The organizational structure of an inspection organization within the CAA, hereinafter referred to as the airworthiness inspection division (AID), will vary depending upon the level and scope of aviation activity within the State and whether an ACD has also been established.
3.4.2 The primary responsibilities of the AID should cover all matters concerning the registration of aircraft, continuing airworthiness, approval of maintenance organizations, maintenance certification of operators and, where no separate personnel licensing division exists, the licensing of aircraft maintenance personnel. In those States where an ACD is not established, it will normally be necessary for the AID to be responsible for those engineering tasks associated with continuing airworthiness, in which case suitably qualified staff will need to be employed.
3.4.3 Approvals and certificates
The AID should:
a) record, review and process applications for registration of aircraft, registering and de-registering aircraft as appropriate, and issuing Certificates of Registration;
b) survey aircraft for issuance, renewal and validation of Certificates of Airworthiness and the subsequent execution of such documents as appropriate; and
c) issue and review of Maintenance Organization Approvals and Air Operator Certificates (AOC).
3.4.4 Surveillance, investigations and enforcement
The AID should:
a) periodically review the airworthiness condition and records of aircraft on the registry in order to assess the adequacy of their maintenance and the competence and diligence of the persons and organizations who perform the maintenance;
b) investigate, in coordination with the ACD, significant defects discovered in aircraft and determine corrective action to be taken where airworthiness may be affected. Analyze defect experience to detect and correct any trends and to reveal areas most in need of airworthiness improvement, and establish a service difficulty reporting (SDR) system (for guidance on SDR systems, see Part III, Chapter 4, Section 4.4.4);
c) in conjunction with the ACD, review aircraft and component manufacturers’ service bulletins and airworthiness directives issued by foreign airworthiness authorities to determine their applicability to the national aircraft, and direct corrective action where airworthiness may be affected (guidance on the implementation of Airworthiness Directives is provided in Part III, Chapter 4, Section 4.4.5);
d) in conjunction with the ACD, approve minor modifications to aircraft, aircraft components and equipment;
e) conduct periodic surveillance of the maintenance-related facilities, procedures and work of holders of AOCs, making appropriate directions and recommendations and approving amendments to the operator’s AOC and to its maintenance organization’s procedures and quality control manuals as appropriate;
f) survey the facilities, procedures and staffing of applicants seeking approval to conduct maintenance on aircraft, and the issuance and renewal of such approval;
g) assess the qualifications of approved persons within an organization, and of other persons as alternates, to perform certain maintenance-related airworthiness functions, and monitor of the activities of these persons;
h) recommend and, where necessary, issue directives concerning the maintenance, overhaul and repair standards to be met by aircraft and aircraft components and equipment, and issue procedures to be followed by the aviation industry to comply with the national air law and regulations related to airworthiness;
