How to get an EASA Part-66 Maintenance Licence

Introduction

The aviation industry places a high premium on safety and technical expertise. For aircraft maintenance engineers, holding an EASA Part-66 Maintenance Licence is essential for ensuring aircraft airworthiness and pursuing a successful career in aviation maintenance. This article will guide you through the process of obtaining the licence, while answering key questions such as: What is the EASA Part-66 licence? What is the difference between EASA Part-66 and Part 147? How do I get an EASA license? What is the primary difference between the B2 and B2L licenses? And, which countries accept EASA licenses?

What is the EASA Part-66 Licence?

The EASA Part-66 Maintenance Licence is a certification issued by the competent airworthiness authority of  a European Union Aviation Safety Agency (EASA) member state that qualifies an individual to certify the airworthiness of an aircraft after maintenance. This licence is a crucial credential for engineers who wish to work on aircraft registered in EASA member countries. It is part of a regulatory framework that ensures uniform safety and maintenance standards across the aviation sector.

Unlike general engineering qualifications, the Part-66 licence is aviation-specific and focuses on the skills and knowledge required for maintaining and certifying various types of aircraft, including aeroplanes, helicopters, and business jets.

What is the difference between EASA Part-66 and Part-147?

EASA Part-66 and Part 147 are closely related but serve distinct purposes in aviation training and certification. Part-66 establishes the standards for individual maintenance engineers, including the knowledge and experience they must demonstrate to obtain a licence. On the other hand, Part-147 governs Approved Maintenance Training Organisations (AMTOs) that provide the necessary training and examinations for aspiring engineers.

In simple terms, Part-66 sets the requirements for the licence, while Part-147 outlines how training and examinations should be conducted. Attending a Part-147-approved institution ensures you receive structured and compliant training that meets EASA standards.

How do I get an EASA Licence?

Obtaining an EASA Part-66 Maintenance Licence involves several steps, which include meeting educational requirements, gaining practical experience, and passing examinations. Below is a detailed overview:

1. Choose the Right Category

   EASA EASA Part-66 licences are divided into different categories, each corresponding to specific aircraft and systems:

   • Category A: Basic maintenance tasks.
   • Category B1: Mechanical systems, including airframes, engines, and associated systems.
   • Category B3: piston-engine non-pressurised aeroplanes of 2 000 kg Maximum Take-off Mass (MTOM) and below.
   • Category B2: Avionics systems
   • Category B2L: Avionics systems with a modular approach to specialized functions.
   • Category L: composite sailplanes, sailplanes, composite powered sailplanes, hot air balloons, gas balloons, hot-air ships
   • Category C: Base maintenance tasks for large aircraft

    

   Selecting the right category depends on your career goals and interests in aviation maintenance.

    

2. Meet Educational Requirements

   You need a strong foundation in mathematics, physics, and engineering principles. A high school diploma with a focus on science or technical subjects is typically required. Enrolling in a Part-147-approved training organization can significantly enhance your chances of success.

    

3. Gain Practical Experience

   To qualify for the licence, you must accumulate hands-on experience in aircraft maintenance. The duration of experience varies depending on your educational background:

   • 2 years for candidates who complete a Part-147 approved course.
   • 3 years for candidates with relevant technical education.

   • 5 years for candidates without formal training.

      

4. Pass the Examinations

   You must pass a series of approved examinations covering theoretical and practical knowledge. These exams are rigorous and test your understanding of aircraft systems, safety protocols, and maintenance procedures. Training at a Part-147-approved organization ensures you are well-prepared for these tests.

    

5. Apply for the Licence

   Once you meet all requirements, submit your application to the relevant EASA member state competent airworthiness authority. Ensure all supporting documents, including proof of experience and examination results, are included. Processing times may vary depending on the authority.

   NOTE: 
   The process may vary from one airworthiness competent authority to the other. The majority of EASA Member state would want to ensure that the applicant has a long term relation with the country or state from where the applicant is requesting the issuance of the licence. Normally this involves demonstrating that the applicant has the right citizenship and/or the right working relationship with an EASA approved maintenance organisation.

What is the primary difference between B2 and B2L licences?

The EASA B2 and B2L licences both focus on avionics systems but differ in scope and specialization:

• B2 Licence: Covers a wide range of avionics systems, including communication, navigation, and autopilot systems. It is a comprehensive certification for engineers handling advanced avionics. A B2 Licence holder needs to undergo aircraft type training for each aircraft type he/she intends to work on. This licence is valid for Complex Motored Powered Aircraft

   

• B2L Licence: Introduced as a modular alternative, the B2L licence allows engineers to specialize in specific avionics functions, such as electrical systems, instrument systems, or radio systems. This licence is ideal for those seeking targeted expertise. This licence is applicable to non-complex motored powered aircraft.

The choice between B2 and B2L depends on your career objectives and the type of aircraft you intend to work on.

Which countries accept EASA Licences?

The EASA Part-66 Maintenance Licence is recognized in all EASA member states, which include the European Union countries and associated states such as Norway, Iceland, Liechtenstein, and Switzerland. Additionally, several non-EASA countries accept the licence due to bilateral agreements or its reputation as a gold standard in aviation maintenance.

Some of the non-EASA countries that accept the licence include:

• The United Arab Emirates
• Singapore
• Malaysia
• Qatar
• Australia (with additional requirements)

Before working in a specific country, confirm its regulatory acceptance of the EASA Part-66 licence.

Conclusion

Earning an EASA Part-66 Maintenance Licence is a significant achievement that opens doors to a rewarding career in aviation maintenance. By understanding what the licence entails, the difference between EASA Part-66 and Part 147, and the specific requirements for each category, you can chart a clear path to success. Whether you choose to pursue a B2 or B2L licence, the recognition of this certification in numerous countries ensures global opportunities for skilled engineers.

Start your journey by selecting a reputable Part-147 training organization, and with dedication and effort, you can achieve this prestigious certification and contribute to the safety and reliability of the aviation industry.
