We recognize that the independent evaluation of our Safety Management System (SMS) through the IAS is critical to maintaining continuous safety improvements and a healthy corporate culture.


The Air Charter Safety Foundation’s (ACSF) Industry Audit Standard (IAS) is a revolutionary audit program that provides a comprehensive, independent review of an operator’s adherence to safety and security regulations. The ACSF Industry Audit Standard (IAS) is the only audit that specifically evaluates compliance with Federal Aviation Administration (FAA) Part 135 (and/or 91 Subpart K) regulations. The IAS requires an SMS to be in place and evaluates the SMS based upon published International Civil Aviation Organization and FAA standards. Operators must adopt and implement operational risk assessment. An on-site IAS audit is required every 24 months.
