GM4 21.A.7(b) Integration of ICA between products (aircraft, engines, propellers) ED Decision 2021/007/R The aircraft/engine/propeller type-certificate holder (TCH) should ensure the availability of ICA to allow maintenance of the aircraft, including engines/propellers when installed on the aircraft. When referring to engine/propeller ICA directly in the aircraft ICA, the aircraft TCH should not perform additional verification and validation. However, the integration and interface aspects between the aircraft and the engine/propeller are still under the responsibility of the aircraft TCH. If the ICA published by the aircraft TCH include some engine/propeller ICA developed by the engine/propeller TCH, the engine/propeller TCH should make an arrangement with the aircraft TCH setting out engine/propeller TCH and aircraft TCH shared responsibilities with respect to the ICA under point [21.A.7](#_DxCrossRefBm1649096932). This arrangement should: — define the part of the engine/propeller ICA which is published in the aircraft ICA; and — address the development, publication and update processes of these ICA, including completeness and timely availability aspects. The incorporated engine/propeller data content remains under the responsibility of the engine/propeller TCH, and the publication is under the responsibility of the aircraft TCH. Therefore, the aircraft TCH must coordinate with the engine/propeller TCH regarding any modification or alteration of the incorporated data. ##### GM4 21.A.7(b) Integration of ICA between products (aircraft, engines, propellers) *ED Decision 2021/007/R* The aircraft/engine/propeller type-certificate holder (TCH) should ensure the availability of ICA to allow maintenance of the aircraft, including engines/propellers when installed on the aircraft.
