Or are you already an experienced mechanic with an Aircraft Maintenance Licence from outside of Europe, and you want to work in the EU? Like Australian CASA, FAA from USA or ICAO licence from some other countries?
Then you have come to the right guide!
Today, we will unfold the details of EASA Part 66 Modules and its exams, which are the basic requirements before applying for the Part 66 licence.
In this guide, we will be covering all the Part 66 modules and the means of approaching them, as some can be challenging because of their extensiveness.
But don’t worry – we’ll break it down in simple terms here.
You will get a clear picture of what each module touches on, how critical it is, and the way you might ace the exams for licensure. In this way, you will have a confident feeling about your abilities to pass the exams for all the required modules.
Why do we have to study modules of EASA Part 66 in the first place?
The world of aviation is a complex one-on-one hand, but you still have to be detail oriented as each mistake can cause serious problems down the road. With this reason in mind, the European Aviation Safety Agency (EASA) has set strict rules on the subjects of knowledge for the aircraft maintenance staff.
Basic knowledge is organised into multiple modules that every trainee must learn and understand.
These EASA Part 66 modules form the core knowledge of every aircraft engineer, equipping you with the ability and skills needed to uphold safety in aviation maintenance.
EASA Modules Categories
To become a licenced aircraft maintenance personnel under EASA regulations, you must complete a series of specific basic modules based on the type of licence you are pursuing (A, B1, B2 or B3).
These are known as Part 66 modules and are divided according to several categories of licences, such as:
Category A: Basic maintenance tasks.
Category B1: Engine & airframe maintenance, including aircraft structure, engines, and mechanical systems such as fuel system & flight control …etc.
Category B2: Electric & avionics maintenance, covering aircraft electronics & electrical systems such as VHF / HF / VOR …. etc.
Category B3: Specialises in piston-engine non-pressurized aircrafts below 2000 kg.
Category C: Licenced aircraft maintenance engineer able to release to service an aircraft after a complex maintenance checks
EASA Part 66 module list
The syllabus contains 17 modules, each of which focuses on a specific area of expertise to ensure that maintenance personnel have a comprehensive understanding of multiple systems and components in an aircraft.
Let’s take a closer look at the contents of the modules listed by the EASA regulation:
Now for you to know which Part 66 modules you have to take in order to apply for a specific category licence, we will cover them here in more detail. As per your desired licence category, you do not need to pass all the modules.
You will skip the ones that do not apply to your situation.
