Fazenda Santa Maria Airstrip

There is no official documented reason for the closure. As a small, private airstrip serving a farm ('fazenda'), the closure was almost certainly due to economic or operational reasons. Common causes for such closures include the farm changing ownership, the owner ceasing to operate aircraft due to high costs, or the land being deemed more valuable for agricultural cultivation than for maintaining a runway.

The site is no longer an active airstrip. Current satellite imagery confirms that the land has been fully reclaimed for agricultural purposes. The faint outline of the former dirt/grass runway is still visible, but it is completely overgrown and has been integrated into the surrounding crop fields. The area is actively being farmed.

The airstrip held no major public or historical significance. Its purpose was purely utilitarian, serving the logistical needs of the Fazenda Santa Maria. Operations would have been limited to private general aviation, supporting the farm's agricultural business. This likely included the use of small single-engine aircraft for transporting personnel, light cargo, and potentially for agricultural aviation (crop dusting). The identifier 'BR-1539' is not an official ICAO code (which begin with 'S' in Brazil) but rather an internal or third-party database identifier.

There are no known plans or prospects for reopening the Fazenda Santa Maria Airstrip. Reopening would require a significant investment from the landowner to clear, regrade, and re-certify the runway with Brazil's National Civil Aviation Agency (ANAC). Given that the land is currently productive farmland, a return to aviation use is highly improbable.
