The European Aviation Safety Agency (EASA) is the centrepiece of the European Union’s strategy for aviation safety. Its mission is to promote the highest common standards of safety and environmental protection in civil aviation.
The Agency’s mandate is twofold. It shall provide technical expertise to the European Commission by assisting in the drafting of rules for aviation safety in various areas and providing technical input to the conclusion of the relevant international agreements.
In addition, the Agency has been given the power to carry out certain executive tasks related to aviation safety, such as the certification of aeronautical products and organisations involved in their design, production and maintenance.
