The Board acknowledges the Civil Aviation Safety Authority and the Aerospace Industry for their essential support and assistance, which enables the Board to operate and to bring to you this useful site. It has a range of information to help those involved in NDT in the Australian Aerospace industry.

Welcome to the website of the National Aerospace
Non Destructive Testing (NDT) Board of Australia

Our Objectives

The Board's objectives are listed in our publications found on the site. The most fundamental of these is to work with CASA to advance and promote aircraft safety, through the correct application of NDT in aircraft maintenance. Intergral to this is the oversight and recognition of employer based qualification and examination programs which comply with applicable industry standards. The Board offers this oversight, and an interpretation guideline to help industry, training organisations and NDT technicians understand how to apply the available standards. The Board is also a reference point for the Aerospace Industry on NDT matters, and its membership's wide expertise makes it well placed to do this. Transition to EN4179 The Board for many years has promoted the adoptation of EN4179 to align Qualification and Certification of the Australian Aerospace NDT Industry with that of the many other countries. The widely used AS3669-2006 has now been revised to the AS3669-2025 edition. AS3669-2025 alignes the training, experience and ongoing revalidation requirements for all NDT certification Levels with EN4179 and removes the competency based training appendix of AS3669. Those AMO's using AS3669-2006 should consider revision of their procedures to comply with the current 2025 edition. Airliner Heli Prop

AS3669:2025 Aerospace – Qualification and approval of personnel for non-destructive testing (EN4179:2021, IDT) has now been published. 

Not revisied since 2006, the 2025 revision now includes significant changes to the qualification and revalidation of Aerospace NDT personnel. The NANDTB recommends that those MRO’s that reference AS3669 should review the new requirements
