EASA Regulation Part 66 Introduction
EASA Regulation Part 66 (Derived from Joint Airworthiness Authorities (JAR) JAR 66 establishes the requirements for issuing an Aircraft Maintenance Engineers License (AMEL) to support the process to manage the competence of Aircraft Maintenance Engineers.
Similar to other EASA regulations The Part 66 Regulation is divided into two parts.
Section A which sets out the requirements that must be met by Industry.
Section B deals with the procedures to be followed by the competent authorities.
In order to be entitled to exercise certification privileges on a specific aircraft type, the holder of aircraft maintenance license need to have his/her license endorsed with the relevant aircraft ratings.
The endorsement of aircraft type ratings requires the satisfactory completion of the relevant category B1, B2 or C aircraft type training.
In addition the endorsement of the first aircraft type rating within a given category / subcategory requires also satisfactory completion of the corresponding On-the-Job Training, as described in Appendix III to Annex III (Part-66).
Aircraft type training shall consist of theoretical training and examination, and, except for the category C ratings, practical training and assessment.
Theoretical training and examination shall comply with the requirement and shall be conducted by a maintenance training organization (MTO) appropriately approved in accordance with Annex IV (Part-147) or, when conducted by other organizations, as directly approved by the competent authority.
Practical training and assessment shall comply with the following requirements. Shall be conducted by an MTO appropriately approved in accordance with Annex IV (Part-147) or, when conducted by other organizations, as directly approved by the competent authority which will also comply with the approved standard.
The training shall include a representative cross section of maintenance activities relevant to the aircraft type and demonstrations using equipment, components, simulators, other training devices or aircraft.
The training shall have been started and completed within the 3 years preceding the application for a type rating endorsement.
The aircraft type training is divided into three levels, namely:
Level 1: A brief overview of the airframe, systems and powerplants as set out in the Systems Description Section of the Aircraft Maintenance Manual/Instructions for Continued Airworthiness.
Course Objectives Level 1:
Level 1 training, the student will be able to provide a simple description of the whole subject, using common words and examples of typical terms and identify safety precautions related to the airframe, its systems and powerplant.
It will be able to identify manuals relating to the aircraft and determine maintenance practices important to the airframe, its systems and powerplant.
Will be able to define the general layout of the aircraft's major systems and general layout and characteristics of the powerplant. Identify special tooling and test equipment used in connection with the aircraft.
Level 2 Training: Basic system overview of controls, indicators principal components including their location and purpose, servicing and minor troubleshooting. General knowledge of the theoretical and practical aspects of the subject.
Course objectives Level 2:
In addition to the information contained in the Level 1 student will be after completion of Level 2 training, able to understand the theoretical fundamentals, apply their knowledge in a practical manner using detailed procedures.
Remember precautions to be observed when working on aircraft, powerplant and systems or in their vicinity.
Describe systems and aircraft handling particularly access, power availability and sources. Determine the locations of the principal components and explain the normal functioning of each major system, including terminology and nomenclature.
It will also be able to perform the procedures for servicing associated with the aircraft for the following systems: Fuel, Power Plants, Hydraulics, Landing Gear, Water/Waste, and Oxygen.
Be able to demonstrate proficiency in use of crew reports and on-board reporting systems (minor trouble-shooting) and determine aircraft airworthiness per the MEL/CDL. Will be able to demonstrate the use, interpretation and application of appropriate documentation including instructions for continued airworthiness, maintenance manual, illustrated parts catalogue etc.
Level 3: Detailed description, operation, component location, removal/installation procedures and bite and troubleshooting to maintenance manual.
Course objectives Level 3:
In addition to the information contained in Level 1 and Level 2, the student after completion of Level 3 training, shall be able to demonstrate theoretical knowledge of aircraft systems and structures and their relationship to other systems, provide a detailed description of the subject using theoretical basic knowledge and specific examples and interpret results from various sources and measurements, as well as carry out, if necessary, corrective action.
The student will also be able to carry out systems, powerplant, component and functions as specified in the maintenance manual of the aircraft, and shall be able to demonstrate the use of appropriate documentation including structural repair manuals, manuals for trouble-shooting etc. interpret and apply it.
To have a full understanding of and be able to correlate technical information for the purpose of making decisions in respect of fault diagnosis and rectification in accordance with the maintenance manual.
