To assist in the evaluation of proposed structural inspection programs for commercial jet transport aircraft, a logic was developed to simulate structural defects, failures, and inspections. This logic was incorporated in a computer program entitled Structural Area Inspection Frequency Evaluation SAIFE. With the objective of quantifying the evaluation process currently used to establish and modify inspection intervals, SAIFE accounts for the following factors 1 aircraft design analysis 2 fatigue testing 3 production, service, and corrosion defects 4 probability of crack or corrosion detection and 5 aircraft modification economics. As a five-volume document, this report covers the initial contract effort plus a subsequent parametric analysis as follows Volume 1 presents the SAIFE logic and documents the methodology for the decision-making processes in the simulation logic. Volume 2 presents the background data for the analytical functions and decision- making processes, and includes data for a typical simulation problem. Volume 3 presents data tabulations derived from historical trends and design input data for a SAIFE demonstration problem. As the users manual for the SAIFE computer program, Volume 4 contains detailed computer logic flow diagrams and a complete listing of the program which is written in SIMSCRIPT II.5. Volume 5 presents the results of the program application to a hypothetical aircraft and compares these results with the service experience of operational aircraft.
