Fazenda Marazul III Airport

The closure was an administrative action initiated at the request of the aerodrome's operator/owner. The ANAC ordinance explicitly states the cancellation was 'a pedido do interessado' (at the request of the interested party). This is a common reason for the closure of private airstrips and is not related to accidents or military conversion. The reasons for the owner's request are typically economic, such as the sale of the property, cessation of aviation activities by the owner, or a desire to avoid the costs and regulatory burden of maintaining a registered airfield.

The site is now a defunct, unmaintained airstrip on private land. Analysis of recent satellite imagery shows the clear outline of the former dirt/grass runway. However, it is visibly overgrown with vegetation and shows signs of disuse, making it unsuitable for any aviation operations. The land has effectively reverted to agricultural or pasture use, with the former runway remaining only as a scar on the landscape.

Fazenda Marazul III Airport, which had the official ANAC ICAO-style identifier SIZX, was a private airstrip. Its sole purpose was to serve the logistical needs of the 'Fazenda Marazul III,' a large farm or ranch in a relatively remote part of the state of Mato Grosso. In regions like the Pantanal, private airstrips are vital for providing rapid transportation for farm owners, managers, and high-value supplies, as well as for emergency medical access, bypassing underdeveloped or seasonally impassable roads. Operations would have been limited to small general aviation aircraft, such as single-engine piston or turboprop planes, consistent with private agricultural and personal use.

There are no known public plans or official prospects for reopening the airport. Since it was a private facility closed at the owner's request, any initiative to reopen would have to come from the current landowner. This would require a significant investment to restore the runway to safe conditions and navigate the complete administrative process to re-register the aerodrome with ANAC. Given these factors, the prospect of reopening is considered extremely low.
