3 airports

The Val d’Oise department is home to one of the main European and international airport hubs with Paris Roissy- Charles de Gaulle International Airport, a global platform for air transport and freight, the business airports of Paris-Le Bourget and Pontoise-Cormeilles-en- Vexin, in Cergy-Pontoise. Paris-Roissy-CDG employs 85,000 people in 700 companies and over 200 occupations in 11 main business fields.

SIAE - First global aeronautics fair

Every two years, Val d’Oise hosts the first International Space and Aeronautics Fair (SIAE) in Le Bourget that brings together all of the global stakeholders in the aeronautics industry around the latest technological innovations.
The exhibition’s 300,000 m2 provide the opportunity to discover aircraft on the ground and in flight and to meet with 2,000 companies (including some 50 from the Val d’Oise department) from around the world.

Close-up of a sector

The aeronautics sector employs nearly 175,000 people1 in France. It includes 350 companies, mostly parts manufacturers and sub-contractors the majority of which are SMEs recognised for their know-how. The sector dedicates 15% of its turnover to R&D. Val d’Oise accounts for 10% of the aeronautics jobs in the Île-de-France region, concentrated in Argenteuil-Bezons, Cergy-Pontoise, in the Montmorency Valley or near the Paris-Roissy-CDG and Paris-Le Bourget airports.
Val d’Oise and the aeronautics industry, a history that dates back to the previous century. The first aircraft were manufactured outside of Paris, along the River Seine, just like cars. Some buildings on the site of the Dassault Aviation establishment which is involved in assembling military (Rafale) or civilian (Falcon) aeroplanes were built at the beginning of the previous century.

Val d’Oise covers all fields of aeronautics

A veritable aeronautics territory equipped with three airports, the Val d’Oise department covers the whole range of occupations in the aeronautics and airport services industry.
• Aircraft construction, both military and civilian: Dassault Aviation and Airbus Helicopters.
• Aeronautic sub-contractors : numerous SMEs (Aertec, Cefival, Chromalloy, Goodrich Actuation System Sas, Hispano Suiza, Laroche, Le Joint Français, Mäder, etc.) work here for Boeing, Airbus, Dassault, Embraer, etc.
• Aeronautic fasteners (hanging, rivet): two rivet manufacturing units, Lisi Aerospace (Blanc Aero industries) and Alcoa in Cergy- Pontoise, form an international centre of excellence in this field.

Aeronautics maintenance: Dassault Falcon Service for private jets ; Air France Industries KLM Engineering & Maintenance for servicing nearly 1,500 aeroplanes belonging to 150 national and international airlines ; Vector Aerospace France (formerly Seca), another specialist in turboprop maintenance and engines.
Pilot training and practice with Air France-KLM, Flight Safety, Sim Aero Training, etc. which run flight simulators, as well as specialised centres, for general aviation, such as Hispano Suiza, a leader in France.
Aircraft ground handling, grouping together several companies around the Paris-Roissy-CDG and Paris-Le Bourget airports, such as France Handling, Universal, Signature, etc. as well as catering companies (aeroplane refuelling, food, blankets, magazines, in-flight duty-free shops, etc.) such as Servair, New Rest, Uppersky Gourmet, etc.

Aeronautics continues to investments in Val d’Oise

In three years, major manufacturing projects have confirmed that Val d’Oise is the territory in which the aeronautics industry has invested the most.
Air France Industries KLM Engineering & Maintenance inaugurated the « Zephyr», in Roissy-en-France in 2012, a test bench for reactors on an international scale capable of carrying out tests on large aeroplane engines like those on the Boeing 777 and A380.


This building (€43 million) allows around 300 aeroplane engines to be tested each year. Hélios (€45 million) is home to the Aerostructures sector for Air France Industries KLM in a new building in Roissy-en-France, to attract the «aerostructures» market for fleets in the making: B787, A350.
Airbus Helicopters (80,000 m2) is opening a manufacturing (production of blades, logistics, offices, restaurant) and R&D site at the Paris-Le Bourget airport. Finally, numerous SMEs and mid-cap companies are undertaking substantial projects for production sites in Val d’Oise, proof of this sector’s development.
