Significant Factors

Summary

  1. The pilots of CYC were conducting in-flight familiarization training using the emergency power lever. That procedure was not contained in the aircraft manufacturer's pilot operating handbook.
  2. The engine manufacturer's documentation contained information on the use of the emergency power lever, which did not preclude the use of the emergency power lever for in-flight familiarization training.
  3. The engine sustained a flameout at an altitude above mean sea level from which reignition of the engine was not successfully completed.
  4. Erosion of the first-stage compressor blades would have reduced the aerodynamic efficiency of the compressor blades.
