EASA Regulatory Essentials: A Comprehensive Introduction to Parts 21, M, 66, 145 & 147

Course Overview

This course provides a detailed understanding of the European Union Aviation Safety Agency (EASA) regulatory structure and its application to aircraft design, production, maintenance, and personnel licensing. It introduces learners to the core EASA Parts — 21, M, 66, 145, and 147 — explaining their scope, technical requirements, and interrelationships. Participants will gain insights into certification processes, continuing airworthiness, maintenance standards, and training organization approvals under the EASA system.

Learning Objectives

• Understand the structure, purpose, and responsibilities of EASA and its Member States.
• Explain the role of ICAO and its Annex system in shaping international aviation safety.
• Interpret the key EASA regulations and their functions within the aviation industry.
• Describe the main provisions of EASA Parts 21, M, 66, 145, and 147.
• Recognize the links between EASA regulatory Parts and global safety frameworks.
