The KSI Report is the culmination of an industry effort initiated by the Certification Process Study (CPS) effort and directed to be implemented by Commercial Aviation Safety Team (CAST) through Safety Enhancement #24. The KSI Development Team consisted of aircraft and engine manufacturers, airline operators, and aviation regulatory agencies. The goal of the project and the report is to increase the level of aviation safety via an Advisory Circular that describes methods and processes whereby OEM�s can make operators aware of Key Safety Information. All parties have worked together to develop a mutually agreed document that also outlines operator�s and regulatory agency�s responsibilities in the process.
