EADS Military aircraft is working on evaluation of modern ultrasonic equipment and coupling systems, for maintenance conditions and final assembly aircraft with focus on modern CFRP structures and corrosion problems on aging aircraft. To get the state of the art, a lot of approaches from conventional UT up to ultrasonic phased array have been investigated so far. The use of a high mobile phased array equipment allows a very comfortable and fast ultrasonic inspection under aircraft maintenance condition. The scans of the structures appear very plastic and give a good inspection tool to the inspector. Gate technique during Data evauluation is a good possibility to work out the defects from the scan by suppress the structure indications, so also not NDI people may get a feeling for a defect with less explanation. The sensors are very flexible for different inspection cases. The biggest problem is good coupling and also a constant angle of incedance, for reproduceable inspection results. EDAS is on a high level with the waterbox construction, but never the less, there are exciting problems to scan close to disturbing structures. There is still capable of improvement.
