AC Aero expands into U.S. General Aviation markets. Andrew Higgs, President has formally established AC Aero USA LLC with the immediate intentions of launching the Lycoming performance products and Higgs Diesel product lines to customers in the United States.

Karl Grove, CEO of AC Aero USA LLC has been appointed to establish and run the entity stateside and will lead sales, marketing and operations within the continental U.S.

A complete line of performance products will be available for the Lycoming 320, 360, 390 and 540 engine variants. We are focused on providing performance based solutions for the GA, EAB as well as other markets. Over the last several years we have been perfecting designs, production, manufacturing and marketing strategies prior to market entry.

“We are now ready to provide the products, service and product quality to our customers. Through the recent CEO appointment of Karl Grove I feel we have the infrastructure in place to make that happen,” said Andrew Higgs, AC Aero President.

Many improvements and content are being added to the site weekly in order to better communicate information and specs necessary for our customers.

We are now accepting reservations for all of the AC Aero product lines and further announcements will be forthcoming as we move towards taking deposits for all product lines.

Our ‘Build Centers’ will also be announced soon. Customers will be able to visit, see and experience our products first hand and either fly their aircraft in for refit or send in their core for overhaul or we’ll just build you a new turnkey engine.

We look forward to announcing more about the AC Aero USA journey in the coming weeks.
