Operational Safety Audits

ICF International is the leading expert in aviation safety audits and operational integrity evaluations, auditing, and consulting, and is one of the founding Audit Organizations within the International Air Transport Association (IATA) Operational Safety Audit (IOSA) program.



IATA developed the IOSA program to streamline the ever-increasing proliferation of operational inspections, reviews, and audits required by the airline industry. With the implementation and international acceptance of IOSA, airlines and regulators achieve several benefits: 

  • A reduction in costs and audit resource requirements for airlines and regulators
  • Elimination of audit redundancy through mutual acceptance of audit reports
  • Continuous updating of standards to reflect regulatory revisions and the evolution of best practices within the industry
  • A structured audit methodology, including standardized checklists
  • Accredited audit organizations with formally trained and qualified auditors
  • Development of auditor training courses for the airline industry

ICF International knows the IOSA program—the original IOSA requirements were developed from the legacy Code Share auditing system utilized by several air carriers and alliance networks. Since 1995, ICF has performed operational safety assessments based on Safety Architecture, our independent, proprietary auditing methodology. ICF developed this comprehensive audit methodology based on internationally recognized audit and operational standards, advanced auditor training in forensic auditing, and a structured system for the sharing of audits, in order to help improve operations and reduce the number of audits in the industry.

ICF has assembled a team of experienced aviation safety professionals located around the globe. Each member of our team is a highly skilled aviation safety professional whose expertise, experience, and insight makes the IOSA experience a learning experience. Our aviation safety professionals exceed the stringent IOSA training and qualifications standards. Every IOSA audit team is led by an industry professional with extensive management and leadership credentials, hence ensuring that a thorough, fair, effective, and timely audit is conducted. Additionally, because our team is located around the world, we can minimize travel expenses, reducing the costs of the overall audit while providing auditors fluent in Arabic, French, German, Greek, Italian, Japanese, Portuguese, Russian, Spanish, and Tagalog.
