Aircraft MRO | Turgis Gaillard

Aircraft maintenance, repair and overhaul are carried out by a dedicated Turgis Gaillard subsidiary: Blois Aéro Services (BAS). For the company’s teams, aircraft availability is a constant concern, and every effort is made to get aircraft back in the air as quickly as possible.

The company's founder, Gérard Guy, have created an admirable state of mind within the company. The top priority is customer service, whether civilian or military, to ensure that aircraft get off the ground to perform their missions. Here, everyone knows the importance of their work.

BAS mainly works on business jets (Cessna Citation), single-engine aircraft (Pilatus PC-6, Piper PA-46 Meridian M500 and M600, Daher TBM family) and twin-engine aircraft (Beechcraft King Air 90 and 200, Beechcraft 1900, De Havilland Canada DHC-6 Twin Otter, Piper PA-42 Cheyenne), and occasionally on piston-engine aircraft.

The company also has an avionics workshop and an engine shop, with considerable expertise in Pratt & Whitney Canada PT6 turboprops.

BAS has been based at the Blois-Le Breuil airfield since 2003, and today has three hangars totaling 2,400m²: one dedicated to the maintenance of civil aircraft; another, built in 2022, for the maintenance of military aircraft; and a third reserved for special projects.

Work is also regularly performed outside the workshops, to troubleshoot AOG (“Aircraft on Ground”) or carry out scheduled maintenance. Two technicians are permanently on standby, ready to intervene anywhere in the world.

Madagascar, Sierra Leone, Burkina Faso, Sudan and Turkmenistan, we travel to wherever our customers operate their aircraft.

The teams at Blois Aéro Services perform airworthiness oversight, line maintenance (official checks and scheduled maintenance, troubleshooting, replacement of defective components, minor repairs), equipment maintenance (batteries, wheels, etc.) as well as more extensive repairs and modifications, such as:

engine modifications. BAS is a Black Hawk authorized agent and can apply STCs (supplementary type certificates) to fit more powerful, more environmentally-friendly or more modern engines to existing aircraft.
avionics retrofit. BAS is a Garmin and S-TEC authorized dealer, and its teams can install glass cockpits, change radios, radars and navigation equipment, and install or retrofit autopilots.
structural modification. BAS technicians regularly carry out major aircraft modifications and repairs, such as corrosion treatment, or wing box replacement. For example, a DHC-6 Twin Otter was recently converted into an amphibious aircraft by the company’s teams.

Military business has been expanded since Blois Aéro Services joined Turgis Gaillard in 2020. First as a subcontractor, for French Air and Space Force aircraft, then since January 2023 as the holder of the through-life support contract for the French Army’s PC-6 Pilatus, awarded by the French State Aircraft Maintenance Department (DMAé).

We're proud to give our forces the best possible availability. We understand their constraints: we've shared them. Most people here come from operational squadrons. We do everything we can to hand over aircraft as quickly as possible.
