JCB Aero Gains Part 145 Approval for Boeing 737 Family

JCB Aero has secured Part 145 maintenance approval to perform base and line maintenance on the Boeing 737 aircraft family, expanding the French facility’s capabilities beyond its established Airbus operations.

The approval, received in August 2026 and announced by the company on September 3, 2026, covers the Boeing 737-600, Boeing 737-700, Boeing 737-800, and Boeing 737-900 variants. Located in Auch, near Toulouse, the subsidiary of the AMAC Aerospace Group initially launched its MRO operations in October 2024 with a focus on Airbus airframes.

Expanding MRO capabilities in Auch

The addition of Boeing 737 maintenance authorization allows JCB Aero to capture a broader segment of the narrowbody market. The company stated it has already begun issuing quotations for Boeing operators and expects to induct the first 737 airframes into its hangar in the coming months.

This expansion follows a period of high utilization for the Auch facility. Earlier in 2026, AMAC Aerospace reported full hangar capacity at the site, driven by maintenance and modification projects on Airbus Corporate Jets, specifically the ACJ318 and ACJ319 platforms.

Management perspective on the Boeing approval

The certification aligns with recent leadership transitions at the company, including the March 2026 appointment of Sébastien Kubler as Chief Operating Officer. Kubler previously served as the technical director of production and engineering for the firm.

In a statement regarding the new certification, Kubler highlighted the strategic value of the dual-manufacturer capability:

“Receiving this Boeing approval marks an important milestone in the development of JCB Aero’s MRO activities. Adding the Boeing 737 family to our existing Airbus capabilities enables us to serve a wider range of customers and further strengthens our position as a flexible and responsive MRO partner. This achievement is also a great recognition of the commitment and expertise of our teams.”

AirPro News analysis

Securing Part 145 approval for the Boeing 737 family represents a logical progression for JCB Aero as it matures its MRO footprint in southern France. By diversifying its capabilities to include both major narrowbody platforms, the facility reduces its exposure to single-manufacturer fleet dynamics. We view this dual-platform capability as a standard requirement for independent MRO providers seeking to maximize hangar utilization and attract mixed-fleet operators.
