SECTION 3.

QUALIFICATION OF PERSONNEL 3.1 Procedures for the Qualification of NDT Personnel.

All Approved Maintenance Organizations involved in any aspects of NDT shall develop and maintain procedures for the qualification and authorization of their NDT personnel.

The BCAD/FSI recognizes and accepts NDT qualifications from the following bodies.
Revision: Original Date: 24th April 2012 Page 2  AC 05-008 - PERSONNEL CERTIFICATION FOR NON DESTRUCTIVE TESTING OF AIRCRAFT, ENGINES, COMPONENTS AND MATERIALS Persons qualified in accordance with the scheme for Personnel Certification in Non- Destructive Testing (PCN) administered by the British Institute of Non-Destructive Testing.
Persons qualified in accordance with EN473 “General Principle for Qualification and Certification of NDT Personnel.” Persons qualified in accordance with the procedures and standards of the American Society for Non-Destructive Testing, (ASNT).

Persons qualified in accordance with the Canadian CGSB procedures and standards.
The holder of an appropriately type rated AMT license in either categories “A” or “C” may issue a Certificate of Release to Service to cover Non-Destructive Testing Inspections on aircraft or components, within the privileges of the license, only for inspections requiring the use of a field kit for the Colour Contrast Dye Penetrant technique.

Note: Type II penetrant examinations shall not be used for final acceptance examination of aerospace products.
In addition, Type II penetrant examinations shall not be used prior to a Type I penetrant examination of the same surface.

SECTION 4 QUALIFIED STAFF 4.1 Approved Maintenance Organizations undertaking NDT must satisfy the BCAD/FSI that they have adequate numbers of suitably qualified staff to discharge the responsibilities of the approval.
4.2 Approved Maintenance Organizations shall nominate in writing, supported with evidence of certification, an individual responsible to the Accountable Manager for the technical supervision of NDT.

This individual will hold independent certification at Level 3 in accordance with Section 3 in the appropriate industry sector and will be referred to as the “Nominated Level 3”.
This position shall be identified within the Maintenance Procedures Manual (MPM) and any change in this position advised to the BCAD/FSI.

4.3 Where the Nominated level 3 is not qualified in all methods used by the Organization, then additional Level 3 personnel necessary to provide coverage shall be independently certified.

4.4 Additional Level 3 Certification holders shall be listed in the MPM or reference made in the MPM to other documents containing the list of Level 3 holders.
Any changes to this list are to be notified to the BCAD/FSI through appropriate amendments.

SECTION 5.

Inspections and Certification of Inspections.

5.1 NDT inspections shall be carried out by personnel approved in accordance with the AMO’s written practice.
Where NDT procedures are specified by the organization responsible for the design and/or manufacture of the aircraft, material, structure or component, then these must be used, except where change is permitted and authorized as defined in paragraph 6 of this advisory circular.
Where non mandatory inspections are to be undertaken, for which the responsible design/manufacturing organization has not specified NDT procedures, then the NDT method, technique, procedure and instruction shall be prepared in accordance with paragraph 6 of this circular and approved by a Level 3 holder qualified in the applicable method.
