Delta receives FAA approval to implement PCRT

摘要

In the USA, Delta Air Lines' maintenance division, Delta TechOps, has received Federal Aviation Administration (FAA) approval to implement process compensated resonance testing (PCRT), a method of non-destructive testing that identifies over-temperature conditions in aircraft engines. The PCRT inspection method replaces the previous original equipment manufacturer (OEM) sample-based destructive inspection of suspect turbine blades. Developed by Vibrant Corp, PCRT is a relatively new aerospace technology that provides environment-friendly, cost-effective and fast reporting on the structural integrity of components. In particular, PCRT offers increased sensitivity to defects, less engine down-time and reduced waste from blades that test negative for over-temperature conditions.
