The fan track assembly includes a body of collapsible material that is positioned within a cavity of the fan case and a spring arrangement provides as system that is operable to perform during normal operating conditions as well as during catastrophic blade failure conditions. In particular, the improved fan track design contemplates a liner that displaces sufficiently at energies less than large foreign object destruction type events.
