Who we are
The company is located since 1973 in the very heart of the French aircraft industry, Toulouse.
There, by providing engineering services to Airbus and other major OEMs, SIER has grown its extensive know-how in aircraft mechanical design and installation of furnishing & equipment.
SIER has also a long history of in-service support, thanks to its participation to a former JV holding a DOA offering aircraft modifications & repairs to cargo deck & cabin interiors, oxygen / water / air / waste / electrical systems installation….
To ensure a better responsiveness and flexibility to our customers, we have recently developed our own DOA (EASA DOA 21J.659). Respectful of our people, our partners and subcontractors, oriented towards sustainability, SIER’s management style enjoys long term relationships and loyalty to its customers.
Also, the continuous involvement of SIER into European R&D programs guarantees a high level of expertise on material, processes and safety, with the use of the latest advanced technologies. SIER’s philosophy is to provide end-to-end management of changes & repairs projects, from the investigation of safe - while cost effective and low risks - solutions, up to the support to embodiment of your changes & repairs.
