Dassault Aviation
A proud heritage
Dassault Aviation, though formally dating from the post WWII era, originated in WWI with Marcel Dassault’s creation of the Éclair propeller, fitted on SPAD fighters and noticeably improving performance.
Thus began a heritage of precision, performance, and even beauty, which was always considered when designing a new aircraft. The first business jet from Dassault, the Falcon 20, flew in 1963 and entered service in 1965. The company set up a formal service organization with the formation of EFS, now DFS, two years later, dedicated to providing complete and exception service support for the new business jet line.
DFS Le Bourget is the largest Falcon service center in Europe, capable of handling 25 Falcons at once. That is large and comprehensive by anyone’s standards. And yet service is highly personalized.
As the Falcon fleet grew, so did the service organization, with factory service in the U.S., then elsewhere. Today that network includes a global MRO network of 40 factory service locations and 20 additional authorized service centers. As new service locations have come online, they have often done so with direct assistance from the experienced team at DFS. Moreover, DFS constantly dispatches its experts around the world to support AOG repairs and assist other centers as they introduce new capabilities.
Dassault MRO
A world of service for the Falcon fleet
The Dassault MRO network spans the globe with service centers and GoTeams at the ready.
The Dassault Factory MRO network includes 40 facilities in all corners of the globe. They perform routine inspections, heavy maintenance and upgrades. They dispatch teams to help new customers place aircraft into service and to respond to AOG situations. They are supplemented by 20 authorized service facilities and 15 parts distribution facilities, the two largest near Paris and at Teterboro, New Jersey
Falcon operators can expect one uniformly high standard of service within the Dassault MRO factory service network, and each location has the full support of the factory itself and the Engineering department when needed.
These MRO locations offer major and minor upgrades for Falcons, such as the FalconEye Combined Vision System and a flight deck upgrade for 7X and 8X aircraft to the EASy IV flight deck.
Dassault makes it easy to plan and schedule maintenance and find the best slots and most appropriate capabilities. Coordination is simplified by having a single point of contact in the Western Hemisphere and in the Eastern Hemisphere. AOG response is coordinated by the Falcon Command Center which never sleeps, supplemented by the Maintenance Command Center for Europe, Africa , the Middle East and Asia.
