Instructions for Continued Airworthiness are the documentation set that describes the maintenance, inspection, repair, and overhaul tasks needed to keep an aircraft or component airworthy throughout its service life. In technical publications, ICA appears as a distinct category of source data referenced by maintenance programs, repair manuals, service bulletins, and continuing airworthiness summaries, and it must remain consistent with approved design data throughout the product life.
Translators encounter ICA in continuing airworthiness sections of maintenance manuals, type certificate data supplements, and repair station documentation. It appears when distinguishing mandatory continued airworthiness requirements from general maintenance guidance, and in cross-references to service bulletins or airworthiness directives. Localizers must preserve the document category label rather than rendering it as a directive.
A frequent error is translating “Instructions for Continued Airworthiness” as “airworthiness directives” or “continuous airworthiness instructions,” conflating a document category with mandatory airworthiness action. This causes maintenance documents to sound legally binding when they are not, or to blur the boundary between manufacturer instructions and regulatory requirements. Another mistake is abbreviating ICA as a proper name in the target language without explaining it.
EASA and CE certification impose language requirements on maintenance and safety documentation. These terms carry airworthiness and liability implications, so they are rendered against the governing standard rather than translated freely.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
