An organisation’s exposition details which 059 version is applicable
1. Non-Destructive Testing (NDT) is a standard maintenance procedure used in the Australian Defence Force (ADF) and refers to tests applied to structures or aeronautical product to detect internal, surface or subsurface defects or discontinuities using methods which do not damage the properties or quality of the item being tested.
2. Methods of NDT currently employed in the ADF are detailed in AAP 7002.043-36-Non-Destructive Testing General Procedures.
3. The Technical Airworthiness Regulator (TAR) has appointed Authorised Engineering Organisations (AEOs) for NDT which operates under the direction of the Directorate General Technical Airworthiness–ADF (DGTA–ADF).
4. This chapter prescribes the responsibilities and procedures to be followed to effectively conduct NDT.
MANAGEMENT RESPONSIBILITIES AND PROCEDURES
5. Scheduled NDT. Scheduled NDT requirements for a particular aeronautical product is initially specified by the Original Equipment Manufacturer (OEM), and may be revised periodically by the responsible Systems Program Office (SPO) due to in-service failure/deterioration. Scheduled tests are specified in authorised maintenance data.
6. When an Approved Maintenance Organisation (AMO) identifies a requirement to have a specific NDT procedure developed, an AEO appointed for NDT is to be tasked with developing the procedure, through the responsible SPO. The Certified NDT Procedures developed by the AEO appointed for NDT are forwarded to the responsible SPO for design acceptance prior to publication and use.
7. Unscheduled NDT. Unscheduled NDT requirements may arise as the result of a defect investigation, aircraft incident or AMO request which may require a General NDT procedure to be used. Unscheduled NDT shall be authorised in accordance with Section 8 Chapter 7-Non-Destructive Testing Procedures.
Levels of Personnel Performing NDT
8. All Technicians/Operators performing NDT on ADF aircraft are qualified and certified to AS 3669:2006-Non-Destructive Testing–Qualification and Approval of Personnel–Aerospace.
9. Personnel performing NDT are designated as Level 1 Limited, Level 2 and Level 3. Technician/Operator levels are indicative of the training, experience and scope of work performed by the Technician/Operator. NDT tasks can be performed, and results of the test certified by:
NDT Task Certification
10. Tasks performed by NDT Technicians have no requirement for Trade Supervision or second level certification and are to be certified as Self Certifying Tradesperson tasks in accordance with Section 4 Chapter 2-Recording and Certification of Aircraft and Aeronautical Product Maintenance.
NDT Technician Certification
11. Level 1 Limited and Level 2 Technician certification is performed by Non Destructive Testing and Composite Technologies (NDT&CT) Certification Section. Level 3 Technicians are certified by OIC NDT&CT. Certification is documented in the Technicians/Operators record of training and employment document.
NDT Technician Recertification
12. Level 1 Limited and Level 2 recertification is performed by NDT&CT Certification Section during the annual recertification visit. Recertification is documented in the Technicians/Operators record of training and employment document. Level 3 NDT Technicians will receive a Letter of Authority from the OIC NDT&CT to acknowledge the recertification.
13. At the discretion of Certification Section, an extension of up to six months can be authorised for Level 2 Technicians. If a further extension is required (six months maximum) it must be endorsed by OIC NDT&CT. All extensions are to be in writing and are to state the reasons for the extension, the length of the extension and the proposed date for recertification.
14. It is the Senior Maintenance Manager (SMM) or delegate's responsibility to ensure all personnel performing NDT are current. When personnel requiring recertification are unavailable during the annual recertification visit by NDT&CT Certification Section, the parent AMO is to arrange a suitable time for the personnel to be recertified at the parent AMOs expense.
