Porto São Sebastião Airport

There are no official public records detailing the reason for closure. The identifier 'BR-2120' is not an official ICAO code issued by Brazilian authorities, but rather an unofficial code used by third-party aviation databases, indicating it was a private airstrip (aeródromo). The most likely reason for its closure is the cessation of operations by its private owner. This could be due to economic reasons, the sale of the associated property (likely a large farm or 'fazenda'), or the airstrip falling into a state of disrepair and no longer meeting minimum safety standards for operation. The closure appears to be a result of abandonment rather than a formal regulatory action.

As of the most recent satellite imagery, the site is an abandoned airstrip. The single, unpaved runway is still clearly visible from the air but is unmaintained, heavily overgrown with vegetation, and shows clear signs of disuse. There are no visible hangars, terminals, or any other airport-related infrastructure on the site. The land has not been repurposed for another use like farming or construction; it is simply returning to its natural state.

Porto São Sebastião Airport was a small, private airstrip with purely local significance. Located in a remote rural area of Mato Grosso, a major agricultural state, its primary function was almost certainly to provide air access for a large private ranch or agricultural operation. It would have handled small general aviation aircraft (e.g., Cessna, Piper) for transporting personnel, urgent supplies, and high-value, low-volume cargo. It may have also supported agricultural aviation activities like crop dusting. It never served commercial or scheduled passenger flights and was not part of Brazil's public airport infrastructure.

There are no known public plans or prospects for the reopening of this airstrip. As a private facility, any initiative to restore and reopen it would have to come from the landowner. Given its remote location and the significant investment required to clear the runway and ensure it meets safety regulations, reopening is considered highly unlikely unless a new, compelling economic need arises for the property it serves.
