Section 1 of each of the JAA requirements is available at no cost on the JAA website, this Section contains all of the 'requirements'. Section 2 contains the Acceptable Means of Compliance (AMC) and Interpretive and Explanatory Material (IEM) and for that you have to pay (a considerable amount).
If you are referred to a 'JAR' (e.g. JAR-FCL 1.125), it will be in Section 1 and available at no charge on the JAA website.
