The IOSA is the IATA Operational Safety Audit, organised by the International Air Transport Association as the world’s leading audit of flight-safety standards. IOSA is the world's first airline safety audit programme based on internationally harmonised standards. The programme is designed to improve the level of safety throughout the airline industry. By 2007, all IATA Members will need to have successfully undergone the IOSA audit in order to achieve or maintain IATA Membership. |
