Abstract

Abstract: A method for evaluating and controlling the probability of missed flaws in aircraft structure is presented in this paper. The method can control the largest size of the flaws missed at nondestructive testing with high probability of flaw detection and confidence level.This method can also raise the flaw detection probability and avoid flight accidents caused by the missed flaws in aircraft structure.It is simple and convenient for application in engineering.

Key words: nondest ruct ive test ing, aircraft st ructure, reliability, cont ro lling
