This Notice of Proposed Amendment (NPA) proposes to amend the Certification Specifications and Acceptable Means of Compliance for Engines (CS-E) in order to reflect the state of the art and best practices, based on the selection of non-complex, non-controversial, and mature subjects.
- Issue 1: Turbine engine transient over-temperature, over-speed and over-torque limit approval
- Issue 2: Turbine engine medium bird strike and ingestion – Additional integrity assessment
- Issue 3: References to CS-34
- Issue 4: Safety analysis for turbine engines
- Issue 5: Vibration and endurance tests of piston engines installed on a rotorcraft
- Issue 6: Propeller control system components as part of engine type design
- Issue 7: Engine control system development errors
- Issue 8: Turbine engine thrust or power rating achieved during the endurance test
- Issue 9: Corrections
The proposed regulatory material is expected to provide a safety benefit, would have no social or environmental impacts, and would provide some economic benefits by streamlining the certification process. It would also increase the harmonisation with the USA Federal Aviation Administration (FAA) regulations.
