Fazenda São Paulo - Retiro Santa Maria Airport

The closure was due to the airstrip falling into disuse for economic and logistical reasons. As a private airfield serving a farm ('fazenda'), the most probable reasons include a change in the farm's ownership or operational needs, the cost of maintenance becoming prohibitive, or the owner no longer possessing or operating an aircraft. There is no evidence suggesting closure due to a major accident, military conversion, or regulatory action.

As of the latest available information and satellite imagery, the site is completely defunct as an airfield. The former dirt/grass runway is no longer maintained, is heavily overgrown with vegetation, and is largely indistinguishable from the surrounding pasture. The land has effectively reverted to agricultural use as part of the Fazenda São Paulo property.

The airport, more accurately a private airstrip (aeródromo), was named 'Fazenda São Paulo - Retiro Santa Maria,' which directly indicates its purpose. Its historical significance was purely private and logistical, serving the agricultural activities of the farm it was on. Operations would have been limited to private general aviation, likely involving small, single-engine aircraft used for transporting the farm's owners, staff, or essential supplies to and from the remote rural location. It held no public or commercial significance and was never open for public use.

There are no known public plans, official discussions, or prospects for reopening this airstrip. Any potential reactivation would be entirely at the discretion and expense of the private landowner. Given its current state of significant disrepair, reopening would require substantial investment to clear, grade, and potentially recertify the runway with Brazil's National Civil Aviation Agency (ANAC). Therefore, reopening is considered highly unlikely.
