At 23 years old Sébastien Lefebvre, student engineer and private pilot, notices an ageing of the air park. Facing a weak offer of modern aircrafts he decides to develop a brand of innovative and competitive light aircrafts.

A market survey confirms this approach and validates the feasibility of this project. Besides the fact to confirm, it highlights an ageing of the air park and an expectation of pilots and flying clubs.

 He creates the company LH Aviation in May 2004 in North of France. Activity? Develop an innovative two seats sport plane; the LH-10 Ellipse. A major turning for light aircraft market. 

Engaged in an industrial process and quality, LH Aviation leaves the region North in March 2008 to reach the centre of Aerospace Activity of Melun- Villaroche in “Seine et Marne” near Paris, the current headquarters.
