Abstract : This report presents Phase II results of an international Project Arrangement between the Federal Aviation Administration and Transport Canada Aviation for the development and testing of a nondestructive inspection system for aircraft corrosion detection in fuselage lap splice joints. The process is based on D SIGHT, an optical technique developed by Diffracto Limited. This report describes the further development of the D SIGHT system hardware and software based upon results obtained from prototype testing during Phase I. A better understanding of the corrosion process and the sensitivity of D SIGHT has been established by imaging numerous corroded specimens containing both artificially accelerated and naturally occurring corrosion in lap splices. A computer model was developed and validated which can accurately predict D SIGHT signatures for a variety of lap splice geometries. Finally, the new system was field tested at airline maintenance facilities to obtain user feedback.
