São Paulo ATC outage

For 71 minutes on April 9, the radar room that manages aircraft around São Paulo went dark, and Brazil’s aviation regulator said the power failure halted operations in the São Paulo Area Control Centre from 8:58 a.m. to 10:09 a.m. local time. Flights were held on the ground while controllers worked under contingency procedures. (visahq.com) That room is not just for one airport. The São Paulo Area Control Centre helps sequence traffic for the country’s busiest air corridor, so a failure there spills outward fast to São Paulo/Guarulhos, Congonhas, Viracopos, and then to flights connecting through the rest of Brazil. (decea.gov.br) Brazil’s National Civil Aviation Agency, the Agência Nacional de Aviação Civil, said it activated a pre-crisis protocol after the outage. That means the problem was treated as a system event, not a single delayed departure. (visahq.com) (gov.br) The timing made it worse. The stoppage hit in the middle of the morning bank, when aircraft are arriving from overnight domestic routes and turning back out for business-heavy shuttle flights across southeastern Brazil. (decea.gov.br) (gov.br) São Paulo/Guarulhos is the biggest airport in Brazil, and the Transport Ministry said it handled 2,571,698 passengers in November 2025 alone, or 29.11% of all passengers in the Southeast that month. When a control center serving that region pauses, missed aircraft rotations keep showing up for hours after the screens come back on. (gov.br) Congonhas adds another pressure point because it is built for dense short-haul traffic and tightly managed takeoff and landing slots. At an airport like that, even a brief interruption can scramble the rest of the day because there is very little empty space in the schedule to absorb it. (gov.br) Brazil ended 2025 with a record 130 million airline passengers, according to the Ministry of Ports and Airports. More people in the system means less slack when one technical fault hits the country’s busiest hub region. (gov.br) Passengers caught in the disruption also fall under Brazil’s delay and cancellation rules, which the aviation agency lists on its consumer guidance pages. Those rules cover rebooking, refunds, and assistance during long waits, which becomes important once a 71-minute control-center failure turns into half-day delays at the gate. (gov.br) (visahq.com) This landed in a travel season that already looks brittle. The Atlantic reported on April 10 that airlines and airports are dealing with a mix of real operational strain and rising passenger anxiety, so each outage now hits a system that is already running with less trust and less patience. (theatlantic.com) A one-hour outage used to sound like a local inconvenience. In a network built around São Paulo, it behaves more like pulling a fuse on the busiest junction box in the country: the lights come back first, and the backlog clears later. (decea.gov.br) (gov.br)
