Military Aviation Authority certification

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

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
