Overview
Héroux-Devtek is a Canadian aerospace company headquartered in Longueuil, Quebec. Founded in 1942 as Héroux Machine Parts Limited, it developed from a general machining business into a major supplier of landing gear, actuation systems, ball screws, precision-machined parts, and related repair and overhaul services. Its customers and programs span commercial aviation, military aircraft, business jets, helicopters, space-related applications, and the aerospace aftermarket. The company entered landing-gear design and manufacturing in the 1960s. One of its most notable technical accomplishments was the manufacture of landing gear for the Apollo 11 Lunar Module Eagle, which supported the first crewed lunar landing in 1969. This program helped establish the company's credentials in demanding aerospace engineering and manufacturing work. Héroux became a publicly traded company in 1986 and expanded through acquisitions during the following decades. These transactions broadened its capabilities in gas-turbine components, precision machining, military aircraft structures, landing gear, hydraulic systems, actuation, ball screws, surface treatment, and maintenance, repair, and overhaul. The acquisition of Devtek Corporation in 2000 strengthened the company's commercial landing-gear business and led to the adoption of the Héroux-Devtek name. The business operates an integrated aerospace manufacturing network in Canada, the United States, the United Kingdom, and Spain. Its capabilities include engineering and program development, forging and machining, surface treatment, assembly, testing, installation support, and aftermarket repair and overhaul. Facilities have supported large landing-gear systems for aircraft such as the Boeing 777 and 777X, while other sites produce components and systems for military and commercial platforms. In 2019, leadership transitioned from longtime chief executive Gilles Labbé to Martin Brassard, with Labbé becoming executive chairman of the board. The company also expanded through the acquisition of Alta-Precision and a majority interest in Tekalia Aeronautik, adding further landing-gear component and surface-treatment capabilities. In February 2025, Platinum Equity announced completion of its purchase of Héroux-Devtek. The company therefore continued as an active aerospace supplier under private ownership, although detailed post-acquisition ownership structure and executive information are not established in the supplied reference material.
History
Héroux-Devtek traces its origins to 1942, when Héroux Machine Parts Limited was established in Longueuil, Quebec. The early business was involved in machining and manufactured components for industrial and aerospace applications. In 1960, it began designing and producing landing-gear components, creating the foundation for the aerospace systems business that later became its central activity. A major early milestone came in 1969, when the company manufactured landing gear for the Apollo 11 Lunar Module Eagle. The landing gear had to support the spacecraft during lunar descent and landing, making the program an important demonstration of the company's precision-manufacturing capability and participation in a historically significant space project. The corporate structure changed in the mid-1980s. On June 26, 1985, the corporation merged with 2320-4894 Québec Inc., a management company incorporated by senior executives Gilles Labbé and Sarto Richer in connection with Bombardier's sale of its shares. Héroux Inc. became publicly traded in 1986. It subsequently expanded through acquisitions, including McSwain Manufacturing Corporation in 1987, adding gas-turbine-component capabilities, and Métro Machining Corporation and Les Industries C.A.T. Inc. in 1999. In 2000, Héroux acquired Devtek Corporation. The transaction strengthened its position in commercial-aircraft landing gear, and the combined company adopted the name Héroux-Devtek Inc. Further expansion followed in 2004 with the acquisition of Progressive Inc. of Arlington, Texas, a producer of complex structural components for military aircraft. During 2007 and 2008, Héroux-Devtek won design work for landing-gear systems associated with the Learjet 85, Sikorsky CH-53K, and Embraer Legacy 450 and 500 programs. The company continued to build its precision-manufacturing footprint in 2010 through the acquisition of Eagle Tool & Machine Co. and E2 Precision Products in Ohio. In 2012, it sold substantially all of its aerostructures and industrial-products operations to Precision Castparts Corporation, concentrating the portfolio more heavily on landing gear and related aerospace systems. A significant commercial program relationship was established in 2013, when Héroux-Devtek signed a long-term contract with Boeing to supply complete landing-gear systems for the 777 and 777X programs. In 2014, the company acquired APPH, an integrated provider of landing gear and hydraulic systems and assemblies serving original-equipment and aftermarket customers. It marked its 75th anniversary in 2017 and entered an acquisition agreement involving Beaver and CESA in 2018. In 2019, Gilles Labbé moved into the role of executive chairman while Martin Brassard became president and chief executive officer. Héroux-Devtek also acquired Alta-Precision and obtained a majority stake in Tekalia Aeronautik, broadening its landing-gear component and surface-treatment capabilities. Its facilities across Canada, the United States, the United Kingdom, and Spain supported machining, assembly, testing, engineering, surface treatment, and repair and overhaul. In February 2025, Platinum Equity announced completion of its acquisition of Héroux-Devtek. This transaction moved the company from public ownership to private ownership. The supplied reference material does not establish the post-acquisition executive team, transaction value, or any subsequent strategic changes. Héroux-Devtek remains an active aerospace supplier with a portfolio centered on landing gear, actuation, ball screws, precision components, and aftermarket services.
