CS-E 860 Turbine Rotor Over-temperature

• ED Decision 2003/9/RM found in: CS-E Amdt 5 - Engines (Dec 2018)

CS-E 860 Turbine Rotor Over-temperature ED Decision 2003/9/RM (a) The most critical temperature conditions which the turbine rotor(s) can attain in the event of Failures of the cooling air supply must be established by analysis and tests, as appropriate. Failure of individual components of the Engine that can be classified as Extremely Remote need not be included in the analysis or tests. (b) Evidence to demonstrate that instrumentation is not required under [CS-E 60(e)](#_DxCrossRefBm1371447588) may be obtained from endurance running in an Engine or on rigs, or, where adequate margins can be demonstrated, by calculation. Where practicable, the duration of endurance running may be reduced by compensating increases in the test temperature.
