Québec aerospace supplier manufacturing precision aerostructure and aircraft-engine components and assemblies.
Operating context
Groupe Meloche combines precision machining with finishing, inspection, assembly and engineering for aeroengine and aerostructure supply chains. Its 2026 growth transaction adds Rossi Aéro in France to an established Quebec manufacturing base. For aerospace customers, the relevant offer is an integrated component-production chain rather than only machine-shop capacity; the inspected transaction announcement does not establish specific new platform awards.
Canadian footprint
Groupe Meloche publishes an operating presence in Beauharnois, Quebec, Canada, and its current public record anchors Precision aerospace machining and assembly to that Canadian organization.
Beauharnois, Quebec is the published city-level context for Groupe Meloche. It does not imply a street address or exact facility location.
Groupe Meloche combines Quebec aerospace component manufacturing with a broader footprint following the Rossi Aéro transaction. Its integrated machining-to-assembly offer and financing support matter to customers seeking production partners, while the actual transfer of work and capacity needs confirmation.
Interpretation of the public record. Not qualification, endorsement or evidence of buyer interest.
Precision aerospace component and assembly manufacturing
Read technical summary
Groupe Meloche provides integrated aerospace-component and assembly manufacturing, connecting design and engineering with machining, finishing and logistics. Its engine-component work includes precision machining, assembly, validation and inspection through the Hemmingford operation.
Evidence of maturity
The established Québec manufacturing group expanded through Hemmingford. May 2026 financing supports Novacap’s majority ownership and the Rossi Aéro acquisition, but is not evidence that additional planned production capacity is already commissioned.
Commercial availability
Aerospace customers can scope integrated component and assembly supply across engineering, manufacturing and logistics. Programme qualification and Canadian or French work allocation require project-specific confirmation.
Core features
Integrated engineering, manufacturing, finishing and logistics
Precision engine-part machining and assembly
Validation testing and inspection for defined aerospace programmes
On May 4, 2026, Investissement Québec announced CAD65 million in support for Groupe Meloche's strategic growth, involving a Novacap majority acquisition and the addition of France-based Rossi Aéro.
Groupe Meloche currently presents Precision aerospace machining and assembly as part of its public commercial offering.
Financing and disclosed activity
Investissement Québec announced CAD65 million in financing on May 4, 2026 to support the Novacap majority transaction and Rossi Aéro acquisition. This financing amount is not the disclosed purchase price of either transaction.

Questions for a first conversation
01
How will Rossi Aéro and the Quebec sites divide engineering, manufacturing and customer programme responsibilities?
The CAD65million financing is not an acquisition price, and site/staff figures refer to the Quebec footprint described in the announcement.
