CS-E Amendment 7
This Decision amends CS-E to improve the certification of turbine engines to better assess and mitigate the potential hazards from blade failures, especially by better integrating the analysis and identification of the potential threats to the aircraft on which the engine is to be installed. The objective is to ensure a more robust certification process and decrease the risk of substantial aircraft damage and fatalities.
In addition, CS-E is amended to reflect the state of the art of engine certification, improve the harmonisation of CS-E with the Federal Aviation Administration (FAA) regulations and make some editorial corrections. To that end, amendments are made in the following areas: assumptions — oil consumption, instrument provisions, piston engine failure analysis, approval of engine use with a thrust reverser, fuel specifications for compression-ignition piston engines, ice protection, damage tolerance of critical parts, and engine critical parts — static pressure loaded parts.
The regulatory material is expected to improve safety, cause no social or environmental impacts, and provide economic benefits by streamlining the certification process
