EASA Part-66 training
EASA Part-66 regulates the knowledge requirements for Certifying Staff in EASA Part-145 Approved Maintenance
Organisations. The Part-66 is developed from JAR-66 and defines the following categories of Certifying
Staff:
A - Line Maintenance Certifying Mechanic
The category a licence allows an experienced and knowledgeable mechanic the authority to certify certain simple
and routine tasks, provided they have carried out the work themselves.
Category A1 Turbine Engine Aeroplanes
Category A2 Piston Engine Aeroplanes
Category A3 Turbine Engine Helicopters
Category A4 Piston Engine Helicopters
Category A5 Reserved for Airship (to be developed)
B1 - Line Maintenance Certifying Technician - Mechanical
This category is mechanically orientated and covers aircraft structure, airframe systems, engines and propellers
or rotors, as appropriate. Category B1 licence holders will also be able to certify all electrical work including
power and distribution systems and control and indication systems.
NB B1 licence holders may not certify electrics associated with avionics systems
B2 - Line Maintenance Certifying Technician - Avionics
These licences are avionic based and confer privileges similar to those of mechanical technician, covering
electrical power and distribution and control and indication systems associated with avionics systems.
NB B2 licence holders may not certify electrics associated with mechanical systems
C - Base Maintenance Certifying Engineer
What is an EASA Part-66 ‘C’ Licence?
This Licence is required in large Part-145 Maintenance Organisations where multiple Licensed Engineers work on
aircraft. It allows the holder to sign off the aircraft’s final Certificate of Release to Service after a
significant period of maintenance. With a BSc (Hons) Degree, the
experience requirement for this Licence is reduced by several years. However, B Licence holders are required to be
in possession of their license for a minimum of 2 years before applying for a C Licence
EASA Part-147 organisations
The Part-147 replaces JAR-147 and describes the training standards that a training institute has to follow in
order to fulfill the Part-66 requirements. Lufthansa Technical Training, as one of the parent companies of
Lufthansa Resource Technical Training, received its JAR-147 Approval in January 1999 as the first organisation
worldwide.
Part-147 Approved integrated basic training solutions are designed to match customer requirements using proven
teaching methods and world-class facilities for knowledge training, hand skills training and practical
training.
HAND SKILLS TRAINING
The Hand Skills are the tools and techniques related to standard aviation maintenance practices such as:
Basic Metalwork
Riveting and Fastener Techniques
Wire-locking
Pipes and Hoses
Control Cable Swaging
Electrical Cables, Connectors and Looming
Composite Structural Repair (in association with Heatcon Abaris)
PART 66 Category A, B1 and B2 is also available as PART 66 Web-Based-Training (WBT) via the Internet. These
courses are provided as a modular combination of home based Internet training and seminars at a PART 147
maintenance training organisation.
The program covers all modules and includes many interactive lessons to intensify the learning progress. The
seminars provide additional classroom training to supplement the WBT and selected practical sequences as well as
allowing for the execution of the full examinations.
Every student is assigned a dedicated tutor and all student activities are monitored by a learning management
program.
