IOSA assess the airline on eight operational scopes for safety, quality and ISAGO level of conformity as a ground handling service provider at Bandaranaike International Airport, Colombo, Sri Lanka. The audit is conducted by IATA accredited audit organization and ISAGO pool members’ auditors, in accordance with the IOSA and ISAGO Program Manuals, and the standards that are published in IOSA and ISAGO Standard Manuals. Even though the assessment mainly focuses on operational areas, it also includes accountability of organisational management functions relevant to aviation safety.
The IATA Operational Safety Audit (IOSA) programme is an internationally recognized and accepted evaluation system designed to assess the operational management and control systems of an airline. Every IATA member is subject to assessment every 24 months prior to reregistration. All IATA members are IOSA registered and must remain registered to maintain IATA membership. SriLankan Airlines first attained the IOSA operator status in 2006 and ISAGO in 2008 and has retained the registry since then.
