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
New air system
Military Type Certificate (MTC)
Covers whole a/c, including engines and propellers
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
Statement of type design assurance
Dependent on assurance activities an MTC or ADCC may be issued
Def Stan 00-970 ‘Design and airworthiness requirements for service aircraft’ is the default certification specification for MOD military registered aircraft.
It is owned and sponsored by the MAA. The ADS team within the Certification division of the MAA are responsible for its content.
