1 - IOSA audit

The IATA Operational Safety Audit (IOSA) Program is an internationally recognized and accepted evaluation system designed to assess the operational management and control systems of an airline. The IOSA audit creates a standard that is comparable on a world-wide basis, enabling and maximizing the joint use of audit reports. 

All IATA members are IOSA registered and must remain registered to maintain IATA membership.


Aircraft applicability:


  - The IOSA Standards and Recommended Practices (ISARPs) as published in this version of the ISM are applicable only for the audit of an operator that operates a minimum of one (i.e. one or more) multi-engine, two-pilot aircraft with a maximum certificated takeoff mass in excess of 5,700 kg (12,566 lb) to      conduct:

• Passenger flights with or without cabin crew.

• Cargo flights with or without the carriage of passengers or supernumeraries.

ISARPs may not be applied or used for the Audit of an operator that either:

• Does not operate a minimum of one aircraft as specified above, or has all aircraft operations conducted by another operator.

ISARPs may not be applied or used for the Audit of operations that are conducted with:

• Aircraft that have a maximum certificated takeoff mass of 5,700 kg (12,566 lb) or less;

• Single engine aircraft;

• Piston engine aircraft;

• Single pilot aircraft;

• Helicopters;

• Seaplanes.

    - During an audit, ISARPs are applied only to those aircraft that are of the type authorized in the Air Operator Certificate (AOC) and utilized in commercial passenger and/or cargo operations. Certain ISARPs are also applicable to non-commercial operations, and such application is indicated in a note that is part of the standard or recommended practice. Other owned or leased aircraft that are not of the type authorized in the AOC and/or not utilized in commercial air transport operations will not be evaluated during an audit. However, the existence of such aircraft will be referenced with an explanation in the IOSA Audit Report (IAR).
