Flexjet Completes Seventh Air Charter Safety Foundation Industry Audit Standard, Becoming First in Industry

December 14, 2022

  • Successful Completion of Audit Confirms Company’s Consistent Commitment to Safety
  • Flexjet was First in the World to Complete the Air Charter Safety Foundation’s Industry Audit Standard in 2009


CLEVELAND, December 13, 2022Flexjet, Inc., a global leader in subscription-based private aviation, today announced it has, once again, successfully completed the Air Charter Safety Foundation (ACSF) Industry Audit Standard (IAS) audit. Not only has it completed a record-setting seventh audit, but it was the first company in the world to meet and pass the audit in 2009.

Designed specifically for Part 135 and Part 91 aircraft operators such as Flexjet, this audit aims at those who are committed to going far above the minimum safety requirements.

This audit has led the industry in setting high-performing safety standards and has consistently increased the audit’s safety performance evidence over the years. In April 2021, the IAS added the evaluation of an operator’s compliance with FAR 14 CFR Part 5 SMS standards (the FAA SMS voluntary implementation program) and ICAO Annex 19 safety management.

Safety is the highest priority at Flexjet and this announcement is one more in a long line of safety accolades and initiatives. Flexjet announced earlier this year its active conformance with the Federal Aviation Administration’s Safety Management System (SMS) and its 23rd Federal Aviation Administration Diamond Award of Excellence for Aviation Maintenance Technician Training.

In Flexjet’s ongoing efforts to detect and correct aircraft needs as early as possible, the company has adopted:

  • GE Digital’s Maintenance Insight software solution for its fleet operations, which detects aircraft and component degradation before even scheduled maintenance would catch it.
  • Transmission of flight data wirelessly and instantly upon touchdown. This initiative strengthens the company’s safety management system and makes Flexjet the only US-based fractional provider to apply this cutting-edge technology fleet-wide.


“Flexjet’s safety culture is present in everything we do, and this audit is among the accolades that confirm our commitment to providing the safest transportation for our aircraft Owners as well as our employees,” said Flexjet CEO Michael Silvestro. “We are proud to lead the industry in seeking and achieving the highest standards of safety and compliance as well as maintenance excellence.”

The ACSF Industry Audit Standard is an all-encompassing aviation audit for Part 135 and Part 91 aircraft operators. As its name implies, the IAS is the most comprehensive industry audit available, designed for those companies that truly desire to go above and beyond minimum safety requirements.

ACSF President Bryan Burns echoed Silvestro’s enthusiasm for Flexjet’s accomplishment. “Flexjet is truly a premier, elite operator,” he said. “They maintain the world’s highest standards for safety and security by actively participating in SMS, ASAP and FDM. Through the years, our criteria for IAS registry have become far more rigorous, making Flexjet’s commitment to its auditing standards that much more impressive.”
