ANNEX I - Continuing Airworthiness Requirements

MUTILATION OF COMPONENTS
(a) Mutilation should be accomplished in such a manner that the components become
permanently unusable for their originally intended use. Mutilated components should not
be able to be reworked or camouflaged to provide the appearance of being serviceable,
such as by replating, shortening and rethreading long bolts, welding, straightening,
machining, cleaning, polishing, or repainting.
(b) Mutilation may be accomplished by one or a combination of the following procedures:
(1) grinding;
(2) burning;
(3) removal of a major lug or other integral feature;
(4) permanent distortion of parts;
(5) cutting a hole with cutting torch or saw;
(6) melting;
(7) sawing into many small pieces; and
(8) any other method accepted by the CAA.
(c) The following procedures are examples of mutilation that are often less successful
because they may not be consistently effective:
(1) stamping or vibro-etching;
(2) spraying with paint;
(3) small distortions, incisions, or hammer marks;
(4) identification by tags or markings;
(5) drilling small holes; and
(6) sawing in two pieces only.
Section A Subpart F Maintenance Organisation

Reference Description
M.A.601 Scope
This Subpart establishes the requirements to be met by an organisation to qualify for the issue or
continuation of an approval for the maintenance of aircraft other than complex motor powered aircraft
and components to be installed therein not used by licenced air carriers in accordance with
Regulation (EC) No 1008/2008.
M.A.602 Application
An application for issue or change of a maintenance organisation approval shall be made on a form
and in a manner established by the CAA.
M.A.602 AMC Application
An application should be made on a CAA Form 2 (Appendix IX to AMC M.A.602 and AMC M.A.702) or
equivalent acceptable to the CAA.
The CAA Form 2 is valid for the application for M.A. Subpart F (refer to Article 4(2)), Part-145, M.A.
Subpart G (refer to Article 4(2)), Part-CAMO and Part-CAO organisations. Organisations applying for
several approvals may do so by using a single CAA Form 2.
M.A.603 Extent of approval
(a) An organisation involved in activities subject to this Subpart shall not exercise its activities
unless approved by the CAA. To that aim, the CAA shall use the template set out in
Appendix V.
(b) The scope of work subject to approval shall be specified in the maintenance organisation
manual in accordance with point M.A.604. Classes and ratings to be used for the approval
of maintenance organisations are set out in Appendix IV of this Part.
(c) An approved maintenance organisation may fabricate, in conformity with maintenance
data, a restricted range of parts for the use in the course of undergoing work within its own
facilities, as identified in the maintenance organisation manual.
M.A.603(a) AMC Extent of Approval
The following table identifies the ATA Specification 2200 chapter for the category C component rating.
If the maintenance manual (or equivalent document) does not follow the ATA Chapters, the
corresponding subjects still apply to the applicable C rating.
