JAR-FCL was drafted to harmonise European regulations on flight crew licensing in order to facilitate mutual recognition of licences and ratings. However, the Joint Aviation Requirements (JAR) (see the JAA publications) have been implemented under national law and under the full responsibility of each Member State.
Therefore the Rulemaking Directorate is not in the position to interpret or make comments on JAR-FCL requirements. In addition, please note that the Agency cannot intervene in cases where the national JAR text deviates from the original.
The national aviation authorities are responsible for interpreting and implementing JAR-FCL requirements.
We therefore recommend that for assistance in interpreting the JAR-FCL requirements, the national aviation authorities should be contacted directly.
A list of the national aviation authorities can be found here.
