Military Aviation Authority certification
Information about MAA certification which ensures that an air system's design meets appropriate safety requirements.
To ensure 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.
6 Phase Approach
The Military Air Systems Certification Process (MACP) certifies new UK military registered Air Systems and major changes to the type design of new and in-service Air Systems.
The MACP comprises 6 phases, some of which may run concurrently. You can view the 6 Phase Approach 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 |
