Risk-based IOSA
Risk-based IOSA
In today’s dynamic environment, airlines need an IATA Operational Safety Audit (IOSA) that focuses on safety risks, specific to the auditee, rather than applying a "one-size-fits-all" approach. Risk-based IOSA delivers an audit scope that will be tailored for each airline. Furthermore, the new approach introduces a maturity assessment of the airline's safety-critical systems and programs.
Focusing on pertinent safety risks, while maintaining a baseline of safety, Risk-based IOSA increases the effectiveness of the audit and contributes to the overall industry goal of reducing the accident rate
Tailored Audit Scope
Tailored Audit Scope
Audit scoping is based on a combination of industry standards and operator-specific elements such as operational profile, safety events, and the operator's IOSA audit history.
The below example illustrates how different factors will be considered in the audit scoping and how this practice differs from today's process.
Example of audit scoping under a risk-based approach to IOSA
AUDIT SCOPING
Worldwide runway excursion rate has been increasing
An operator has been demonstrating conformity with a non-critical ISARP for several consecutive audits
TODAY
All ISARPs are audited regardless of their universal criticality
All ISARPs are audited regardless of their criticality for the operator
FUTURE
ISARPs are prioritized in regular intervals. In this example ISARPs related to runway excursions are identified as high priority and audited in-depth
The scope is tailored to the Operator's operating profile and audit history.
ISARPs with low criticality may be audited at lower frequency to allow focus on high-criticality ISARP
