GRAY SERVICE CENTER
TROYES SERVICE CENTER
Built on the shared expertise of two sister companies — JG Aviation, founded in 1995, and Troyes Aviation, founded in 1973 — JGA Group holds a leading position in airworthiness management, maintenance and modification services for general aviation in France and Western Europe, with three locations — Gray, Troyes and Paris-Le Bourget — and approvals from five aircraft manufacturers: Pilatus, TBM, Cirrus, Piper and Mooney.
JG Aviation is the authorized Pilatus PC-12 and PC-24 Service Center for France, Belgium and Luxembourg, with an AOG team based at Paris-Le Bourget Airport.
Troyes Aviation is the authorized service center for TBM, Cirrus, Piper and Mooney in France, and is also an avionics specialist with Garmin and Avidyne dealer status.
Bringing the shared DNA of both companies together under a single brand is a natural step forward. That brand is Bellonte Aviation.
The name pays tribute to Maurice Bellonte, who took off with Dieudonné Costes from Paris-Le-Bourget in 1930 for the first Paris–New York crossing. An aircraft engineer as well as a pilot, Maurice Bellonte embodies one of our deepest convictions: technical excellence is the foundation of flight freedom.
His aircraft was called Point d'Interrogation. A bright red Breguet XIX bearing the Alsatian stork, the emblem of France's elite squadrons during the First World War. It took off from Paris-Le Bourget Airport on September 1, 1930, to complete the first east-to-west flight from Paris to New York. At the time, this achievement was considered impossible.
Point d'Interrogation is also the story of two men: Dieudonné Costes and Maurice Bellonte. Costes at the controls, Bellonte overseeing navigation and technical monitoring. They knew their aircraft down to the smallest detail and prepared it without leaving anything to chance.
Like Maurice Bellonte, the aircraft engineer and mechanics who prepared that historic crossing, we carry every mission through to destination. Every aircraft has its own mission, operating environment, constraints, history and technical specificities. Every aircraft has a story.
This is why, under the Bellonte Aviation brand, we offer a complete range of services designed to support every stage in the life of your aircraft:
This promise reflects the standard we set for ourselves in every mission, every project and every aircraft we support. We help preserve each aircraft's legacy by ensuring its records are complete, its maintenance history is clear, and its technical condition is managed with care and precision.
Our teams of dedicated specialists are trained and certified on the aircraft they work with every day. True experts in their field, operating as authorized manufacturer Service Centers while supporting a wide range of general aviation aircraft.
Troyes Aviation and JG Aviation have earned the loyalty of their clients over several decades. With Bellonte Aviation, that story continues. You work with people who have learned to understand your aircraft and will always provide the best guidance for its long-term care.
Predictable costs, defects identified during inspections, a three- to five-year maintenance outlook, and step-by-step follow-up on every intervention. You always know where things stand. Our rates are public, accessible and continuously updated.
AOG assistance, dedicated teams, OEM parts stock and a mobile repair team at Paris-Le-Bourget. Our organization brings together all the services required to support your aircraft, built around one clear priority: your aircraft is available when you need it.
