ComScan 160 II set up for wing inspection.  In order to detect troublesome corrosion in the past, airplanes were periodically disassembled which took thousands of man hours.  With ComScan, the critical regions can be scanned compley without dismantling the airplane

ComScan 160 II has been designed for the inspection of light weight materials such as aluminum, honeycombs, aerospace composite materials, carbon fiber structures, etc.  Unlike conventional X-ray techniques which require both sides of the inspection sample for positioning of the X-ray sourceimaging device, ComScan only requires access to one side of the inspection sample.  This unique feature allows surface measurement of large, thick, bulky objects to be inspected which might otherwise not be possible with conventional X-ray techniques.

The system gives an accurate determination of defect sizedepth.   It is not even necessary for X-rays to penetrate the total inspection sample depth since ComScan utilizes back-scattered radiation.  The system is particularly well suited for the inspection of impact damage, corrosiondefective core conditions.
