Abstract : Recognizing the importance of visual inspection in the maintenance of the civil air fleet, the FAA tasked the Aging Aircraft Nondestructive Inspection Validation Center (AANC) at Sandia National Labs in Albuquerque, NM, to establish a visual inspection reliability program. This report presents the results of the first phase of that program, a benchmark visual inspection reliability experiment. The benchmark experiment had 12 airline inspectors perform specific inspection tasks on AANC's Boeing 737 in order to estimate overall performance characteristics of a typical set of inspectors on a typical set visual inspection tasks. The report also includes a separate but related probability of detection study on small but visible cracks at rivet locations on fabricated fuselage skin splices. Conclusions are drawn with respect to quantification of inspection reliability, search and decision aspects of visual inspection, use of job cards during inspection, and inspector specific factors affecting visual inspection performance.
