In the world of aviation, there are a number of organizations that set guidelines for all areas of flight. Since aircraft are tasked with carrying valuable cargo from one place to another, safety is paramount in every phase from construction to lift-off to overseas travel. One such organization, known as the EASA (European Union Aviation Safety Agency) aims to promote safety in aviation, worldwide. 

Overview

The primary objective of the EASA is to facilitate the movement of European products and services throughout the world. Although the EASA works closely with and for each of the 27 EU member countries, partnerships with authorities and organizations around the globe work to support a set of global safety standards.

As part of this global reach, the EASA has international offices in the United States, China, Canada, and Singapore. 

The Importance of the EASA

Again, the EASA organization targets the entire aviation industry around the world, working to strengthen cooperation, provide safety information, and implement agreements. The efforts, in turn, encourage uniformity when it comes to standards of excellence in aviation safety.

Bilateral Aviation Safety Agreement

A BASA unifies the EU and several non-EU countries in support of EASA initiatives. The United States currently has a BASA in place with the EU in recognition and acceptance of EASA certificates and rules. For example, EASA implementing rule 66 is a regulation that defines conditions by which a maintenance engineer is able to gain (through a company approval) authorization to work on, certify, and release an aircraft into service after a maintenance operation.

An EASA Part-66 license is very valuable for those who wish to enter the field of aviation mechanics.

EASA Part-66 Categories and Training Modules

When it comes to aircraft maintenance licenses, there are a number of license categories according to the EASA. They are as follows:

Categories

Category A

Category A1 – Certifying Mechanic Piston Engine Powered Fixed-Wing Aircrafts

Category A2 – Certifying Mechanic Turbine Engine Powered Fixed-Wing Aircraft

Category A3 – Certifying Mechanic Piston Engine Powered Helicopter

Category A4 – Certifying Mechanic Turbine Engine Powered Helicopters

Category B

B1.1 – Certifying Technician Piston Engine Powered Fixed-Wing Aircrafts

B1.2 – Certifying Technician Turbine Engine Powered Fixed-Wing Aircraft

B1.3 – Certifying Technician Piston Engine Powered Helicopter

B1.4 – Certifying Technician Turbine Engine Powered Helicopters

B2 – Certifying Technician Avionics

B3 – Certifying Technician Ultra-Light Aircraft

Category C

Category C – Certifying Engineer

Modules

In order to obtain a license in a particular category, one has to complete certain training modules and pass a number of exams. Not all modules need to be completed for each category, but here is a comprehensive list of all EASA Part-66 training modules for reference:

Module 1 – Mathematics

Module 2 – Physics

Module 3 – Electrical Fundamentals

Module 4 – Electronic Fundamentals

Module 5 – Digital techniques / Electronic instrument systems

Module 6 – Material and Hardware

Module 7 – Maintenance practices
