 Easy Access Rules for Airworthiness and Environmental Certification (Regulation (EU) No 748/2012) EASA eRules: aviation rules for the 21st century Rules are the core of the EU civil aviation system. The aim of the EASA eRules project is to make them accessible to stakeholders in an efficient and reliable way. EASA eRules is a comprehensive, single system for structuring, sharing, and storing of rules. It is the single, easy-access online database for all aviation safety rules applicable to persons and organisations subject to Basic Regulation (Regulation (EU) 2018/1139). The Easy Access Rules (EAR) are the output of the eRules project. The EAR books are consolidated versions of those rules, combining EU regulations with the related EASA Executive Director (ED) decisions in an easy-to-read format with advanced navigation features through links and bookmarks. The EAR books are regularly updated, following the adoption of an official publication. The EAR books are available: — in PDF format; — as dynamic online publications (online format) with a wide range of functionalities, such as filters to obtain regulatory material tailored to one’s needs, a search function through the table of contents to quickly access the relevant sections, and easy navigation for computers, tablets, and mobiles; and — in XML (machine-readable) format that can be easily processed and automated by recipients, producing output that is compatible and can be synchronised with local applications, search databases, etc. The EASA eRules system is developed and implemented in close cooperation with the Member States and aviation industry to ensure that all its capabilities are relevant and effective.
