Write a brief report explaining what are ‘Instructions for Continued Airworthiness (ICA)’ and its importance to aviation. In your report, address the following: What regulations define an ICA, for both the FAA and EASA? What guidance documents exist to help you create ICAs? (e.g. Advisory Circulars, Orders, Certification Standards, etc.) Are the FAA and EASA harmonized in terms of the regulations and Advisory Circulars?
