The ACSF Industry Audit Standard (IAS) was designed to be a single, comprehensive standard for the on-demand air charter and fractional aircraft ownership industry. The IAS comprehensively evaluates both an air charter operator’s or fractional aircraft ownership company’s SMS and its FAA regulatory compliance.
Read testimonials from operators that have gone through the ACSF audit program:
“The experience of having undergone the ACSF audit process left us with a much stronger, cohesive, and safe operation.   The standards set out by ACSF provided us with a roadmap of where we needed to focus our resources to improve or add systems where a shortfall was identified.  In addition, the audit left us with a very clear picture of what we are capable of accomplishing, and how to get there. Meeting this standard has given our organization another tool to grow while keeping safety as our number one priority.”
 - Levi Stockton, President, Advanced Air, LLC
“Priester Aviation is thrilled by its addition to the Air Charter Safety Foundation registry. All of us at Priester Aviation have worked hard to achieve the high level of performance required by the ACSF standards.”
- Andy Priester, President and CEO, Priester Aviation, LLC.

“We are extremely proud of achieving registry status with the Air Charter Safety Foundation. It was an enlightening process and a team-building experience that I have not seen before in our company or industry. The preparation for the ACSF audit was the most comprehensive process we have ever experienced. We have always participated in the outside audit process, but unlike other audits, this was conducted to the International Civil Aviation Organization standards and resulted in fine tuning our entire operation, not just flight operations.”
- William F. Haberstock, President and CEO, Keystone Aviation
“I am thrilled that Mayo Aviation joins the ranks of companies accredited by the ACSF. This elite group of companies represents industry leaders committed to providing the highest level of safety possible. For organizations participating in the Air Charter Safety Foundation audit, safety is no accident. For these organizations, safety is prescriptive, planned and deliberate - a daily focus that permeates everything they do.”
  - Bill Mayo, President and CEO, Mayo Aviation
