What is the EASA Part 66 Guide?

The EASA Part 66 guide is a structured framework created to prepare candidates for the European Union Aviation Safety Agency’s licensing exams. Successful completion of these exams allows engineers to become licensed Aircraft Maintenance Engineers (AMEs), capable of certifying aircraft as airworthy after maintenance.

Unlike regular courses, the EASA Part 66 guide not only details the subjects covered but also helps learners understand exam structures, recommended study methods, and assessment formats.

Importance of Part 66 Modules

The Part 66 modules form the cornerstone of the EASA curriculum. Each module addresses core knowledge areas required in aviation maintenance, ranging from mathematics and physics to highly specialized subjects such as avionics, structures, and propulsion.

Key modules include:

  • Module 1: Mathematics

  • Module 2: Physics

  • Module 3: Electrical Fundamentals

  • Module 4: Electronic Fundamentals

  • Module 5: Digital Techniques and Systems

  • Module 6: Materials and Hardware

  • Module 7: Maintenance Practices

  • Module 8: Basic Aerodynamics

  • Module 9: Human Factors

  • Module 10: Aviation Legislation

  • Module 11–17: Specialized modules covering aerodynamics, engines, airframes, and advanced topics including EASA Module 17 Propeller.


The EASA Part 66 guide ensures students cover each area with focus and precision, essential for exam success.

Understanding the Aviation Exam

The aviation exam under EASA licensing is designed to ensure candidates possess both theoretical knowledge and practical skills.

  • Multiple choice questions assess technical knowledge and memory.

  • Essay or structured questions test deeper application of concepts, calculations, and analysis.

  • Practical assessments evaluate the candidate’s ability to perform real maintenance tasks.


This ensures that license holders are not only technically proficient but capable of applying theoretical knowledge to real-world situations.

Why You Need an EASA Part 66 Guide

Preparing for the aviation exam without direction can be overwhelming because of the sheer number of part 66 modules to cover. The EASA Part 66 guide is essential for:

  • Breaking down complex subjects into digestible formats.

  • Providing practice questions based on real exam patterns.

  • Offering a sequence of study that builds from basics to specialized topics.

  • Reducing study anxiety through structured preparation.


Challenges Students Face

Exam preparation for aviation can be difficult because of:

  • Volume of content: From mathematics to complex aerodynamics, the subjects are vast.

  • Technical depth: Many modules include detailed diagrams, systems, and regulations.

  • Application of knowledge: Passing the aviation exam requires not just memorization but understanding practical maintenance practices.

  • Regulatory updates: Aviation regulations evolve constantly, which means materials must stay current.


The EASA Part 66 guide helps reduce these challenges by presenting reliable, up-to-date resources.

Role of Practice Exams

Mock exams and past papers aligned with part 66 modules allow students to practice under exam conditions.

Benefits include:

  • Familiarity with the format of aviation exams.

  • Time management skills during actual tests.

  • Identifying topics requiring extra attention.

  • Building confidence before sitting the official exam.


Resources like EASA Module 17 Propeller are excellent examples of module-specific practice and study aids.

Focus on Module 17: Propeller

One of the crucial part 66 modules is Module 17: Propeller. It equips maintenance students with the knowledge required for working on propeller systems used in both piston-driven and turboprop aircraft.

Topics covered include:

  • Classifications of propellers.

  • Constant-speed and variable-pitch propeller systems.

  • Governing mechanisms and controls.

  • Propeller maintenance techniques.

  • Safe handling and balancing procedures.


As a specialized field, Module 17 is critical for engineers working with propeller-driven aircraft. In-depth resources like EASA Module 17 Propeller simplify complex areas for effective learning.

Exam Preparation Strategies

  1. Study in Sequence: Follow the EASA Part 66 guide starting from maths and physics (Modules 1 and 2) towards advanced propulsion and avionics modules.

  2. Use Multiple Learning Formats: Texts, video tutorials, diagrams, and online test banks.

  3. Plan Regular Revision: Go back to earlier modules to strengthen retention.

  4. Simulate Exam Conditions: Attempt sample tests within time limits.

  5. Balance Theory with Practice: Apply theoretical knowledge during workshops or internships.


Opportunities After Certification

Clearing the aviation exam and becoming EASA Part 66 certified unlocks global opportunities. Engineers can:

  • Work with airlines, MROs (Maintenance, Repair, Overhaul), and OEMs.

  • Find employment opportunities worldwide, not just in Europe.

  • Earn higher wages as certified AMEs.

  • Progress to specialized or supervisory maintenance roles.


Continuous Learning in Aviation

Even after certification, aviation professionals are required to continuously update their knowledge. New technologies, updated regulations, and modernized aircraft models demand ongoing learning, and revisiting the EASA Part 66 guide helps maintain professional readiness.
