This advisory circular (AC) establishes an acceptable means, but not the only means, to obtain Federal Aviation Administration’s (FAA) airworthiness approval for the installation of an Integrated Modular Avionics (IMA) System that uses hardware elements authorized under Technical Standard Order (TSO)-C153, Integrated Modular Avionics Hardware Elements. The FAA’s TSO process is a means for obtaining FAA design and production approval for an appliance, system, or product; however, the TSO authorization does not provide installation approval. This AC provides guidance for applicants involved in the integration, installation, certification, and continued airworthiness of IMA systems into an aircraft or engine, when the IMA system utilizes hardware elements that comply with TSO-C153. The guidance applies to the entire IMA system, not just the hardware elements. The guidance is specific to installations of these systems on aircraft or engines approved under Title 14 of the Code of Federal Regulations (14 CFR) parts 23, 25, 27, 29, 33, and 35.
