How are EASA approved components released to service following component maintenance activities?

Components are released by the authorized person who signs a Form 1 to release the component as a serviceable component.

Are other checks, tests or inspections considered as a Certificate of Release to Service (CRS)?

Exactly in the same way that the various elements of a base maintenance check contribute to the overall preparation of the completed work package which enables the base maintenance check to be signed by a C certifier, A Component CRS is certified by a person who has the knowledge back ground, experience, and competence to validate that all work has been performed to prepare the component for service.

The Maintenance Training Organisation Exposition (MTOE) defines the organisation and procedures upon which the EASA Part 147 Organisation approval is based. The MTOE must be constructed in such a way that through the document the organisation is able to demonstrate full compliance with all regulatory requirements.
Consider that the purpose of the MTOE is actually two fold:
a) To demonstrate full compliance with the regulatory environment 
b) To describe the most efficient process to enable the organisation to operate in an effective way.
Also to consider that the Accountable Manager is responsible for the overall operation of the Maintenance Training Organisation and considering he has the necessary power to maintain adequate facilities, equipment, materials, technical data and qualified personnel as necessary, pertinent to the operation of the Maintenance Training Organisation. It is important that the contents of the MTOE are fully understood and accepted by the AM.

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.

How to Ensure the Independence of Audits within an EASA Part 147 Organization

When we talk about the Quality System we are off course considering both the function of QA & QC.
The QA audit process must be independent which means the auditor is not involved in the day to deliver delivery of training or management of processes.

It should also be understood that the audits do not replace the need for ongoing Quality Control (QC) activities.

The audits which we will carry out are considered as “compliance audits” and essentially follow a prescriptive checklist ensuring that all elements of the process are delivering in accordance with both the regulatory and organizational requirements.

A Part 66 License belongs to an individual and is valid for 5 years, an organization approval is only valid whilst the holder is employed by the organization and may in fact have expiration's which are limited by other factors. (For example recurrent training validity)
Part-66 licenses facilitate the certification of the release to service of aircraft after maintenance and to work within the Base Maintenance (note the need for company authorization) there is a distinct difference between gaining an Aircraft Maintenance Engineers License (AMEL) and gaining organization approval to certify aircraft.

To become a Licensed Aircraft Engineer, there are basically two routes:

a) The approved course (Taught by a suitable approved EASA Part 147 Training Provider)
Note - In the case of attendance to an approved course, the minimum experience requirement is reduced from 5 years to 2 years for approved course graduates.
b) The self-improver (The Self-Improver Route Requires evidence of 5 years of appropriate experience together with passes in all applicable Part 66 modules. The evidence is then presented to the Competent Authority. (10 years allowed))

The EASA Part 66 license is the qualification that enables the holder with suitable type or task training to provide through organizational approval and in some situations directly the Certification of European registered managed or maintained aircraft to allow a Certificate of Release to Service either through EASA Part 145.A.50 or EASA Part M Subpart H CRS.

What will a Part 66 license allow me to do?

A Part 66 license is a pre-requisite to allow you with appropriate organizational approval to certify the release to service of aircraft after maintenance and to work in maintenance organizations as support staff. It should be noted that all education received in support of Part 66 Basic Aspirations must be acquired under the control and oversight of a Part-147 training organization approved by EASA. There is currently no conversion process available in non EU countries which allow for the issue of a Part 66 license it is necessary to follow fully the EASA Guidelines and process to obtain your Part 66 License.

An application for an aircraft maintenance License or change to such License shall be made on an EASA Form 19 (Form 19 is adopted and issued by each regulatory authority).
The application are normally made under the jurisdiction of the Competent Authority of any European Member State.
Once a member state issues your license you will normally continue to use this Member State (It is possible to change though there is little reason to do so!).
Please note that SofemaOnline works with our Romanian Partner, European Aviation Institute who is an EASA Part 147 approved Maintenance Training Organization (MTO) with Certificate of Approval No RO.147.0003. Therefore the applicable regulatory authority is the Romanian Civil Aviation Authority.

The following information introduces the different Aircraft Maintenance Engineers license types which are available to European EASA Part 66 Licensed aircraft Engineers.
The Basic, non-type rated license also known as a Category “A” License does not in itself convey certification rights, directly but allows the holder to certify “limited and simple maintenance tasks only” as specified on his (or her) “personal authorization Document”.
On the basis of the Maintenance Engineers License, together with satisfactory demonstration of competency and knowledge of organizational procedures the personal authorization document is issued by an approved Part-145 organization.
