Tierra Prietas Airport

The official reason for closure is unknown, as the airport was likely an unofficial or private entity. The most probable reasons are abandonment or forced closure by authorities. Given its remote location in a region known for narcotics trafficking, it is highly plausible that it was a clandestine airstrip ('narcopista') that was either abandoned by its operators or discovered and disabled by the Mexican military (SEDENA), a common practice which involves trenching or plowing the runway surface.

The site is abandoned and the airstrip is in a state of severe disrepair. Current satellite imagery shows the runway is heavily eroded, overgrown with desert scrub, and crossed by numerous vehicle tracks. It is completely unsuitable for any aircraft operations. The land appears to be unused, remaining as open desert terrain.

Tierra Prietas Airport has no known official historical significance. The identifier 'MX-1984' is not an official ICAO code (which begin with 'MM' for Mexico) but rather a user-assigned code found in non-official databases, likely for flight simulators. The facility was a simple, unpaved dirt/gravel airstrip approximately 1,250 meters (4,100 feet) in length, with no hangars, terminals, or other infrastructure. When active, it was likely used for private general aviation, possibly serving a local ranch ('rancho'), or for illicit/clandestine transport operations.

None known. Due to its remote location, complete lack of infrastructure, unofficial status, and the poor condition of the runway, there are no known or plausible prospects for reopening the airstrip for any official aviation purposes.
