Document Title: AC 43-218, Operational Authorization of Integrated Aircraft Health Management Systems
Summary: Automated health monitoring in aircraft maintenance uses onboard sensors, data transmission, and data analysis to provide information regarding aircraft system performance. The result is then used to make aircraft airworthiness determinations that enhance operational safety and provide economic efficiencies. This end-to-end process is known as Integrated Aircraft Health Management (IAHM). This AC provides guidance for developing an operator’s IAHM Program.
