Modern nondestructive testing (NDT) is applied increasingly for improving the reliability and lifespan of aging aircraft. One method, Process Compensated Resonance Testing (PCRT) has recently seen increased implementation in the Aerospace Industry. In cooperation with Vibrant, Delta and Honeywell have largely been involved with the development of PCRT for aerospace applications. PCRT is a long proven NDT method and has been fully implemented and integrated into the automotive industry. The Aerospace and Power Generation Industries are now discovering the benefits that this inspection has to offer. PCRT provides a quick, easy, operator independent method for determining the structural acceptability of parts based on whole body resonance analysis. This technical paper covers the background of the PCRT technology and capabilities as it relates to specific applications for aerospace components. Highlighted are specific details for the application and validation of PCRT for in service testing of JT8D 1st stage high pressure turbine (HPT) blades to improve engine reliability. Experimental information pertaining to high temperature exposure and fatigue are also included. Additional information, related to defect detection in the CF6-80A 1st stage HPT blade and ceramic rolling elements used in hybrid bearings, is included as well. Overall it is clear that PCRT is emerging as a practical and inexpensive (compared to existing inspection methods) technology to use for defect detection, process control, and life monitoring of new and in-service components.
