Developments in techniques for detecting cracks and structural defects could yield monitoring systems that enhance safety while reducing inspection time and cost.
Two technologies in particular show promise. One is comparative vacuum monitoring (CVM) , which uses in-situ sensors. Boeing is adding CVM to its common practices NDT (nondestructive testing) manuals as an option for inspecting commercial airframes. It is reporatedly the first aircraft manufacturer to do so, although CVM is under study by Airbus and other builders.
