ANAC-certified repair stations: the map of Brazilian MRO, state by state
No aircraft flies without a certified repair station. The map of Brazilian MRO says a lot about where business aviation really lives.
Business aviation shows up in photos as a ramp of jets gleaming in the sun. The part that holds it all up sits behind a closed gate: the maintenance hangar, where every flight hour sold out front is born from hours of certified work in here. No aircraft flies commercially without passing through one of these doors.
An ANAC-certified repair station (MRO) is the maintenance organization ANAC certifies under RBAC 145 (Brazil's Part 145 equivalent): only it may perform and sign off the return to service of civil aircraft. Certification is scoped (airframe by model, engine, avionics, propeller, components), the list is public, and where these shops sit on the map says a great deal about where Brazilian aviation really lives.
Why 'certified' is a license, not a badge
Aircraft maintenance is not an open service market. Whoever performs it must be a certified organization, with a quality system, calibrated tooling, qualified staff and approved manuals, all audited by ANAC. The practical consequence is blunt and simple: work signed off by an uncertified shop does not count, and an aircraft with irregular maintenance loses the very standing of its Certificate of Airworthiness.
It is the link that closes the loop: certified air taxi (RBAC 135, akin to Part 135) operators are required to keep aircraft on an approved maintenance program, carried out by these organizations. Registry, operation and maintenance all tie into the same regulatory knot.
The detail that defines markets: scope
"Certified" never means "certified for everything." The certificate lists scopes, and scope defines each shop's addressable market.
| Scope | What it covers | The commercial consequence |
|---|---|---|
| Airframe (by type) | Structure and systems of the listed models | Certified for the King Air does not sign off Phenom work |
| Engine | Listed engine types and models | PT6 turboprop and turbofan are different certifications |
| Avionics | Onboard electronics and navigation | Panel upgrades live here |
| Propeller | Overhaul and repair of the listed propellers | Its own line item, forgotten until it stalls the schedule |
| Components | Bench work: landing gear, wheels, brakes, accessories | The supplier ecosystem around the big shops |
Read the table again with a salesperson's eye: each shop's scope defines exactly the fleet it can serve. Airframe certification for the King Air equals the addressable market of every King Air in the country. That cross-reference (installed capacity times registered fleet) is what Jet Tracker's MRO analytics does automatically.
The map: where maintenance lives
MRO geography follows the fleet's: the São Paulo axis (Sorocaba, Jundiaí, Campinas and the greater capital region) stands as the country's largest hub for executive maintenance, with strong hubs in the South, in Minas Gerais and in Goiás. That is no coincidence: São Paulo held half of Brazil's executive jets in the July 2026 census (Portrait of Brazilian Business Aviation, data as of Jul 12, 2026). In the interior and the North, smaller shops scoped for turboprops and piston aircraft keep the working fleet flying, including the agricultural fleet Jet Tracker Agro tracks.
Choosing the shop for your aircraft
- 01
Scope before price
Confirm in ANAC's public list that the organization is certified for your model (airframe) and for whatever will be touched (engine, avionics). A quote from a shop without the right scope is a quote for a different aircraft.
- 02
Fleet served is a proxy for competence
How many aircraft of your model does the shop actually service? Fleet served means parts on the shelf, mechanics trained on the type, and problems they have already seen before. The MRO directory shows capacity by organization.
- 03
Logistics factor into the bill
Ferrying the aircraft to the shop costs flight hours and schedule. For a heavy inspection, the distant hub can pay off; for routine work, the nearby base wins. The hourly math behind that call is in how much a jet really costs.
- 04
Queue and calendar
Limited capacity means a queue at inspection peaks. Whoever schedules maintenance by watching the market's calendar, not only their own, shaves weeks off aircraft downtime.

Frequently asked questions
What is an RBAC 145 certified repair station?
It is the maintenance organization ANAC certifies to perform and approve the return to service of aircraft and components. The certification lists specific scopes: airframes by model, engines, avionics, propellers and components. A shop without the scope for your model cannot sign off the work.
How do you check whether a repair station is certified?
ANAC publishes the list of certified maintenance organizations and their scopes. Jet Tracker's MRO directory organizes these shops by state, capacity and fleet served, and cross-references them against the registered aircraft to show each one's addressable market.
Does aircraft maintenance have to be done in Brazil?
Not necessarily. Part of the executive fleet has heavy maintenance done abroad, at centers authorized by the manufacturer. The decision weighs cost, turnaround time, ferry logistics, and the installed capacity in Brazil for that model.
