Rancho Grande (Tres Hermanas) Airport

No official reason for the closure is publicly available. As a private airfield, its closure was most likely due to private economic reasons, a change in the ownership of the associated ranch ('Rancho Grande'), or a cessation of aviation activities by the owner. There is no evidence to suggest it was closed due to a major accident, military conversion, or urban encroachment.

The airport is permanently closed and abandoned. The physical location is now part of the surrounding agricultural land. The faint outline of the dirt runway is still visible from satellite view, but it is unmaintained, partially overgrown, and appears to be used as a simple farm track or has been left completely derelict. There is no remaining aviation-specific infrastructure, such as hangars, lighting, or fuel services, on the site.

Rancho Grande (Tres Hermanas) Airport was a private airstrip serving a purely local function. Its name suggests it was built for and operated by the large ranch on which it is situated. Its primary operations would have involved general aviation for the private transport of the ranch's owners and personnel. Given the extensive agriculture in the region (visible as large center-pivot irrigation fields), it is also highly probable that the airstrip was used for agricultural aviation, such as crop dusting. The airport featured a single unpaved, dirt runway (designated 02/20) approximately 1,300 meters (4,265 feet) in length. It held no known public, commercial, or military significance.

There are no known or published plans to reopen or reactivate this airstrip. Given its status as a small, private, and rudimentary airfield that has been defunct for many years, the prospect of it reopening is extremely low to non-existent.
