In Europe, military and state operated aircraft are excluded from the scope of the European Aviation Safety Agency (EASA) legislation. As a result, military airworthiness is regulated only at national level.
The need to improve European defence capabilities influenced decision of the European Defence Agency (EDA) to establish the Military Airworthiness Authorities (MAWA) Forum to develop, adopt and implement harmonized European Military Airworthiness Requirements (EMARs). Up to date, MAWA Forum has developed and approved five sets of EMARs that cover: Initial Aircraft Certification (EMAR 21), Aircraft Maintenance (EMAR 145) , Maintenance Training Organizations (EMAR 147). EMAR M and EMAR 66.
