Delta TechOps highlighted the benefits it has seen through the application of Vibrant Corporation’s nondestructive testing (NDT) services in a presentation at the Airlines for America (A4A) NDT Forum. The presentation, titled “The Future of NDT and the Upcoming Paradigm Shift,” described Delta’s adaptation of NDT protocols in response to new NDT technologies, including Vibrant’s Process Compensated Resonance Testing (PCRT). Delta Principal Engineer David Piotrowski and Product Line Manager Alex Melton highlighted the importance of resonance frequency and mode data provided by PCRT, and the effectiveness of PCRT in detecting unacceptable material conditions like overtemperature in turbine blades. Delta TechOps uses PCRT for FAA-approved NDT of critical components for JT8D and CFM56 jet engines.

“We’re thrilled by Delta’s success in solving critical problems with PCRT,” said Vibrant VP of Operations Greg Weaver. “They’re a great model for the rest of the industry on how to approach NDT from a new perspective.”
