Evaluation of NDT Technologies in Support of CP 140 Aircraft Sampling Inspection.
Abstract
This evaluation was undertaken to identify possible nondestructive inspection systems that will fulfill the requirements of the CP140 Aircraft Structural Integrity Programme (ASIP). The CP140 aircraft is fast approaching its originally intended life expectancy and staff from the Directorate of Technical Airworthiness and the CP140 Aircraft Engineering Office are considering an extension. In that light, the third line support contractor (i.e., Industrial Maritime Products (I.M.P.) Group Limited) has identified critical areas via the Reliability Centered Maintenance methodology. More specifically, the Common characteristic of these areas is the fact that they are not inspected under the current maintenance plan. As a result, data is lacking for a proper assessment of the aircraft structure. Hence, I.M.P. Group Limited has devised a number of Shop Instruction Notes (SINs) for the inspection of these areas that will require the use of nondestructive inspection systems. The proposed SINs call for the inspection of large surfaces, which preclude the use of most nondestructive inspection systems on a cost and time constraint basis. However, two systems were perceived as fulfilling the inspection requirements. They are the Magneto-Optic Imager (MOI) by PRI Research and Development Corporation and the D-Sight Aircraft Inspection System (DAIS) by Laser Measurement International (LMI) Inc. Automotive Division Both of these systems could provide for quick inspection of large surfaces. The evaluation documented in this report provides some insight on the advantages and disadvantages associated with both systems. Eased on the evaluation results, the DAIS should enable the quick inspection of the overall aircraft structure and highlight areas with corrosion. However, this inspection systems will not cover all SINs requirements. This deficiency can only be addressed by the use of other inspections systems.
