The company’s estimated annual revenue of $114.4 million and a workforce of 372 employees provide a solid foundation for leveraging this new certification into sustained business growth.

Background and Company Profile

Founded in 1998 by William Borgsmiller, ACI Jet began as a modest charter operation in San Luis Obispo, California, with a single Piper Seneca III aircraft. Over the years, the company has evolved into a full-spectrum aviation services provider, expanding its fleet, infrastructure, and service offerings to meet the diverse needs of business and private aviation clients.

Strategic investments and partnerships have played a crucial role in ACI Jet’s growth trajectory. In 2014, French investor Olivier Leclercq’s involvement provided the capital necessary for scaling operations and enhancing staff capabilities. Facility expansions at key California airports, including John Wayne Airport and San Luis Obispo County Regional Airport, have further solidified ACI Jet’s presence in the region.

Today, ACI Jet operates across several business verticals, including aircraft management, charter services, maintenance and repair, and Fixed Base Operations (FBO). Its “aviation ecosystem” approach allows it to offer comprehensive solutions, from supplemental charter flights to detailing and fueling, creating a one-stop-shop experience for aircraft owners and operators. This integrated model has become increasingly attractive in an industry where efficiency, reliability, and regulatory compliance are paramount.

EASA Certification: Technical and Regulatory Significance

Achieving EASA Part 145 approval is no small feat. The process, led by ACI Jet’s Quality Control Manager, Isaac Garner, spanned more than a year and required a thorough overhaul of operational manuals, safety management protocols, and internal audit procedures. The certification process included detailed documentation, facility upgrades, and close collaboration with the FAA’s Flight Standards District Office to ensure compliance with European regulatory standards.

The technical scope of EASA Part 145 encompasses stringent facility, personnel, and quality system requirements. Maintenance organizations must demonstrate adequate space, tooling, and safety protocols, while ensuring staff qualifications and independent quality management systems are robust and traceable. These requirements often exceed those mandated by U.S. authorities, setting a high bar for operational excellence.

For ACI Jet, EASA certification authorizes maintenance, repair, and overhaul (MRO) services for European-registered aircraft, a significant expansion given the scarcity of such services on the U.S. West Coast. This is particularly relevant for Bombardier aircraft, as ACI Jet’s status as an Authorized Service Facility allows it to extend factory-trained expertise and warranty support to European operators.

“We made improvements not because we had to, but because we should. That’s the ACI Jet way.” – Isaac Garner, Quality Control Manager, ACI Jet

Market Context and Industry Trends
