Canadian Forces (CF) CF188 Hornet aircraft have been plagued with water ingress and related damage in their composite flight control surfaces (FCS). Water ingress can cause structural degradation including corrosion, delamination and disbond. Two different radiology inspection systems were recently acquired by the CF. A new Neutron Radioscopy system and an X-ray Computed Radiography (CR) system underwent evaluation for detecting water ingress in the composite FCS of the CF188. A Probability of Detection (POD) study revealed that the new neutron radioscopy system has an a90/95 value of 4.65 micro L for water detection. Furthermore, the X-ray CR system demonstrated sensitivity similar to conventional X-ray film radiography; its a90/95 value for water detection is 20.55 micro L. The image plate from the CR system was also used in conjunction with a conversion screen for neutron radiography and was able to identify water defects in the FCS.
