In order to fulfil the inspection requirements of the parts manufactured and maintained, Dassault Aviation has invested in new inspection techniques, in particular Acoustical Interferometry, Acoustical Microscopy and Laser Based Ultrasonics which were amongst the most promising methods within the several NDT-NDE one's emerging and presented here. Each method of course has its own range of applications, unfortunately not one cover the whole required spectrum, and more than two different methods would be necessary if one would want to do it all the most efficient way, nevertheless most current problems and needs can be fulfilled. The main issue with the choice of these techniques is the low production rate of the components to be inspected in the European aircraft and aerospace industries, which do not facilitate their integration. Technical issues for Laser Ultrasonic, in terms of performances and integration will result from the evolving nature of technology. Air coupled ultrasound is already an alternative for contactless inspection and Acousto-ultasonics could be the answer for the more complex parts which will be manufactured for the next generation of aircrafts. A strong alternative associated with the development of new manufacturing technologies such as RTM is Process Control which should enable monitoring and material integrity assessment, thus suppressing final non destructive inspection.
