AN INVESTIGATION ON THE AFFECT OF EXTERNAL CONDITIONS ON THE RELIABILITY OF AIRCRAFT INSPECTIONS

Abstract

The objective of this study is to develop an understanding of how external variables commonly encountered during an inspection affect an inspection systems detection capability. A probability of detection study was performed using representative structural samples, attached to a simulated naval flight asset. For the execution of these tests, common nondestructive testing equipment was utilized by multiple inspectors. For each test inspectors, test samples (with imbedded damage) and inspection locations around the test bed were varied to better simulate field inspection conditions. An understanding of how these variables affect inspection performance will give maintainers, designers, and planners a more realistic idea of what damage can be detected and quantified in field inspection conditions.
