Information about MAA certification which ensures that an air system's design meets appropriate safety requirements.
MAA certification ensures that an air system’s design meets appropriate safety requirements. A systematic, independent certification process is required for both new types of military registered air systems and for major changes to existing designs. This process is detailed within Regulatory Article 1500.
6 Phase Approach
The Military Air Systems Certification Process (MACP) comprises 6 phases, some of which may run concurrently. You can view the 6 Phase Approach document below.
Applicability of the MACP
Whether the full MACP or a tailored MACP approach is applicable depends on project dates with respect to main gate/business case approval. You can view the MACP applicability diagram document below.
Outcomes of the MACP
The potential outcomes of the MACP are shown below
|Change Type||Approach||MACP Output||Comment|
|New air system||Full MACP||Military Type Certificate (MTC)||Covers whole a/c, including engines and propellers|
|Major change||Full MACP||Up-issue of type certificate* or issue an Approved Design Change Certificate (ADCC)**||*If an MTC already issued; **If an MTC has not been previously issued and changes not extensive enough for an MTC|
|New air system or major change||Tailored MACP||Statement of type design assurance||Dependent on assurance activities an MTC or ADCC may be issued|
