Montreal-based business aviation support services company ACASS has been issued its third consecutive renewal of its IS-BAO Stage III registration from IBAC. This designation, first issued to ACASS in 2017, verifies that ACASS's SMS activities are fully integrated into its aircraft management operations and that a positive safety culture is consistently sustained.

“We are constantly expanding and enhancing the support services we offer our clients, but if they don't have complete confidence in our safety standards, those improvements are meaningless,” says Derek Holter, ACASS VP of operations. “Our IS-BAO Stage III makes it instantly clear that safety is our number one priority.”

The International Standard for Business Aircraft Operations was introduced by IBAC in 2003 and ACASS received its initial IS-BAO registration in 2008. It is a code of best practices designed to help flight departments worldwide achieve a superior level of safety and professionalism. The IS-BAO Stage III registration is the highest-level registration issued by IBAC and has been awarded to only a select group of aircraft operators worldwide. Audits are conducted every two to three years to ensure conformance with the standards and recommended practices.

“Transparency, authenticity and integrity are key elements of our corporate identity,” says Andre Khury, ACASS CEO. “When we say we are committed to the highest possible safety standards, we want to be able to tangibly and demonstrably back that up. In terms of safety, the IS-BAO Stage III registration proves that we mean what we say.”
