About us


Founded in 2001, Aviation Quality Services (AQS) is a full-service provider of safety and quality management solutions in the aviation industry. Besides various audit programs, AQS offers training and services worldwide to provide a long-term effect on operational efficiency and performance. 

Our experience

We were the world’s first IOSA Audit Organization (AO) accredited by IATA in 2003 to audit international airlines according to the IOSA standard. As one of the only two IATA Endorsed Training Organizations (ETO) accredited to conduct the IOSA Auditor Training, AQS is able to train new IOSA auditors on behalf of IATA. AQS is economically fully independent; however, as a 100% subsidiary of Lufthansa Aviation Training, we benefit from the financial backing of Europe’s largest airline group.
