What is Safety Assurance in Aviation SMS
In order for an aviation safety management system (SMS) to be effective, the SMS must be monitored to provide assurance to managers and regulatory authorities that the SMS is both
- implemented correctly, and
- working as designed.
An ICAO compliant SMS is structured around four main components, which are also known as the Four Pillars. The third aviation SMS component is Safety Assurance (SA). The primary purpose of safety assurance is to demonstrate the SMS remains functional and alert management of substandard safety performance. Substandard safety performance is corrected under the direction of the Accountable Executive.
