Abstract : This report presents Phase I results of a joint Project Arrangement between the FAA and Transport Canada Aviation for the development and testing of a nondestructive inspection (NDI) system for aircraft corrosion detection in fuselage lap joints. The process is based on D Sight, an optical technique developed by Diffracto Limited. This research project had the following major components: identification of corrosion areas of concern, collection of corrosion samples, acceleration of specimen corrosion in the laboratory, construction and testing of a breadboard inspection device, and laboratory and field trials of the breadboard device. The outcome can be summarized as follows: a library of aircraft corrosion samples has been established, a corrosion process has been developed that matches in-service corrosion well, a breadboard D Sight NDI system has been built and tested, and a proposal for follow-on work has been completed.
