of these, or finding of equivalent level of safety); d) lists of tests to be conducted; e) identification of substantiation reports to be submitted (as proof of compliance); f) identification of persons responsible for making findings of compliance; g) the level of involvement of the ACD, the applicant, or a delegate of the ACD in the
findings of compliance or witnessing of tests; and h) the certification project schedule, including the applicant’s milestones and when final certification is expected.
1.3.3.3.2 Tests, analyses, and inspections are expensive in terms of cost and time. Applicants, therefore, seek concurrence from the ACD that their proposed means of compliance with the certification basis are acceptable. The acceptance of the means, however, is not an acceptance of the data in advance, it is merely a recognition of the means as satisfactory for the demonstration of compliance. The certification compliance plan, although initially agreed to by the ACD, is a living document whose contents may change (the structure and format will remain the same) throughout the course of type certification. Some of the possible sources of change to this document are as follows:
a) design changes due to refinements or development;
b) revised means of compliance;
c) changes in level of involvement of the ACD and applicant;
d) changes to the certification basis caused by the issuance of special conditions of airworthiness, alternate means of compliance, or exemptions; or
e) other issues affecting the design or certification that modify any of the aspects of the certification plan.
1.3.3.3.3 The activities involving demonstration of compliance usually begins after a certification compliance plan has been agreed to between the applicant and ACD. The original (or master) copy of the certification compliance plan is retained by the ACD until completion of the type certification activity. Upon completion of the programme, the plan can be the official certification compliance record for the product.
1.3.3.4 Level of involvement
Some CAAs have regulations that allow delegation of some or all of their functions, duties or powers to qualified individuals or organizations. The responsibilities assigned by the regulations to a CAA, however, cannot be delegated and always remain with the CAA. Under a delegation system, appropriately qualified individuals or organizations may be granted permission or authority to make a finding of compliance on behalf of their CAA. A finding of compliance by a delegate is a finding of compliance by the CAA. As such, an administrative procedure should exist for the recording of the finding of compliance by the delegated individual or organization. Some findings of compliance, however, may be the exclusive responsibility of the ACD and cannot be delegated, or the ACD may limit a delegate to making recommendations only instead of making a finding of compliance. If the applicant proposes to utilize delegated persons or organizations in the certification programme, the exact role of these delegates should be clearly identified in the certification compliance plan and agreed to by the ACD. The levels of involvement of the ACD, applicant and delegates will be defined by the CAA’s delegation system, taking into account such factors as limitations of the delegates, complexity of the type design, availability of technical resources, and time constraints of the certification project.
