CS-E 140 Tests - Engine Configuration ED Decision 2007/015/R (See [AMC E 140](#_DxCrossRefBm1371447669)) (a) The configuration of the Engine or components or parts to be tested must be sufficiently representative of the type design for the purpose of the test. (b) All automatic controls and protections must be in operation unless it is accepted that this is not possible or that they are not required because of the nature of the test. (c) Variable devices that are not intended to be adjusted during Engine operation must be set in accordance with the type design prior to each test, except when the particular test demands adjustments to be made or as required by paragraphs relating to specific tests. Other variable devices must operate or be operated in a manner consistent with both the type design and the operating instructions to be provided under [CS-E 20(d)](#_DxCrossRefBm1371447571) unless otherwise necessary for the purpose of the test. (d) (1) All equipment drives not essential to the satisfactory functioning of the Engine must be disconnected or off loaded during the Calibration Tests of [CS-E 350](#_DxCrossRefBm1371447625) or [CS-E 730](#_DxCrossRefBm1371447624). Throughout all other tests, except as required by CS-E 140(d)(2), they must be suitably loaded, either with the equipment listed in the constructor's declaration or with slave units of a suitable type. (2) When running the additional endurance test sequence required by [CS-E 740(c)(3)(iii)](#_DxCrossRefBm1371447586), the accessory drives and mounting attachments need not be loaded if it can be substantiated that there is no significant effect to the durability of any accessory drive or Engine component. However, the equivalent Engine output power extraction from the power turbine rotor assembly must be added to the Engine shaft output. (e) Certain features prescribed in [CS-E 500](#_DxCrossRefBm1371447610) and [CS-E 560](#_DxCrossRefBm1371447608) to [CS-E 590](#_DxCrossRefBm1371447653) may be incorporated as part of the aircraft installation rather than as part of the Engine type design. In this case, where the performance of the Engine is affected, the features concerned must be satisfactorily represented throughout the Engine tests. (f) In addition to the combined Engine and Propeller tests required by [CS-E 180](#_DxCrossRefBm1371447614), other tests prescribed in Certification Specifications for Propellers may be conducted jointly with Engine tests where it is accepted that these combined tests do not constitute a less severe test for either the Engine or the Propeller or both.
