Ensuring health and safety for all.



Safran Aero Boosters is committed to ensuring the health and safety of people on and around its sites, the safety of its facilities and respect for the environment and neighboring communities, as well as incorporating Health, Safety and Environment regulations into its design, development, manufacturing and distribution processes for its products and services.









Safety, a top priority

Safety is one of Safran Aero Boosters's top priorities. The company takes all practical measures to anticipate, prevent, eliminate, reduce and manage all safety risks arising out of its activities. It has developed a culture of anticipation and prevention to ensure that its staff, partners, suppliers, customers and any site visitors benefit from the highest possible level of risk management.





Improvement approach

Safran +, making headway in the drive for success.




Safran Aero Boosters is working with Safran to implement a continuous professional improvement drive, called Safran +, to provide a framework for improvement initiatives and meet client expectations of excellence.
















Safran Aero Boosters continuously seeks ways to improve both its products and services and its internal processes and operating methods. The Executive Board sets out the annual improvement plan then oversees its implementation through performance indicators updated on a monthly basis. A Total Quality specialists unit backed by a group of experts in various fields, both from the company and from the Safran Group, is assigned to co-ordinate and implement this plan.


Safran + is based on recognized tools and methods including Lean Sigma, QRQC, TPM, Visual Factory, SPC, 5S, SMED, etc.

An offshoot of the Fabrique Nationale de Herstal, Safran Aero Boosters began to acquire expertise in aerospace propulsion in 1949, manufacturing Rolls Royce and General Electric engines under license.

The company achieved international acclaim for its F100 Pratt & Whitney engine fitted in F15 and F16 fighters. It manufactured most of the components and was responsible for assembly and testing of over 600 engines of this type.


The 1980s marked a turning point for the future development of Safran Aero Boosters as it took part in major commercial aviation programs. The company's initial experiments in the aviation industry also led to its inclusion from the very outset in the first European space programs. The company gradually extended its R&D to offer clients end-to-end solutions from design to product manufacture.


Since the year 2000, Safran Aero Boosters has concluded numerous partnership agreements for low-pressure compressors and lubrication equipment in aircraft engines across the whole thrust range. With these agreements, the company is playing its part in financing new engines alongside engine manufacturers and takes full industrial responsibility for the modules and/or equipment, which can represent as much as a 10% share of the full engine.


Safran Aero Boosters has today acquired the technological maturity it needs to go one step further, by playing a real part in developing engine architectures within its sphere of responsibility, alongside some of the biggest engine manufacturers in the industry.



Subsidiaries, added expertise

To more effectively cater to its customers' needs, Safran Aero Boosters has chosen to deepen and widen its expertise by acquiring two subsidiaries: Safran Test Cells and Safran Oil Systems. Its strategy is already paying off.

Safran Test Cells, the world leader in test facilities

Safran Test Cells, a Safran Aero Boosters subsidiary since 2003, designs and produces aircraft engine test facilities for all types of engines, including military and commercial turbofan, turboprop and turboshaft engines.







Available 24H/24

The Minnesota site hosts 80 Safran Test Cells employees , who work in close collaboration with the 100 staff members at Belgium. Being present on two continents – and in two time zones – makes Safran Test Cells all the more efficient when dealing with customers. These include engine manufacturers, maintenance operators, airlines and the armed forces.


Safran Oil Systems, a Safran Aero Boosters subsidiary specialized in oil tanks for aircraft engines



Safran Oil Systems is a Florida-based company specializing in the design, development and production of welded, stainless-steel oil tanks.


An extensive range of oil equipment

Safran Aero Boosters, already the world leader in lubrication pumps at the time, acquired Safran Oil Systems in order to extend its range to all aircraft engine lubrication and cooling equipment. Safran Oil Systems boasts full oil tank design, engineering, manufacturing and repair capabilities and its products currently make up 75% of the world civil market.







Tanks for all engine manufacturers

Safran Oil Systems has made a name for itself on the world stage in its own niche field. Its technique for welding together stainless steel sheet metal performs optimally under weight and fire-resistance constraints, and allows for the creation of oil systems that are perfectly adapted to the needs of all aircraft engine manufacturers, such as Safran Aircraft Engines, General Electric, Pratt & Whitney and Rolls-Royce.

Safran Oil Systems is responsible for the CFMI LEAP, GE Passport, RR Trent XWB, PW1000G and Engine Alliance GP7200 engine tanks.
