Commercial aircraft powered by CFM56 engines

About MRO

Tier-1 OEM manufacturing excellence dedicated to engine component maintenance and fleet availability.

Our Difference

Extend the life of your engine equipment.

At Senior Aerospace Ermeto, Part 145 MRO is not an isolated repair shop: it directly leverages over 70 years of OEM experience in designing, qualifying and manufacturing critical aerospace fluid transfer lines and fittings.

Located at the heart of our Fossé (Loir-et-Cher, France) manufacturing plant near Paris, our MRO repair station has direct access to OEM inspection fixtures, CNC bending and end-forming tooling, and high-pressure test benches used for series production — along with raw material stocks of aerospace alloys (stainless steel, Inconel, titanium) in tube and bar, plus standard fittings and qualified hardware.

This unique synergy between OEM manufacturing and Part 145 MRO enables us to restore the full geometric and metallurgical integrity of your fuel manifolds, rigid tubes and flexible assemblies while optimizing costs and Turnaround Time (TAT).
