Mesa Bonita Airport

No single event has been documented. The closure was most likely due to a combination of economic factors and a lack of sustained demand. Maintaining even a simple rural airstrip is costly. Without sufficient traffic from general aviation, local business (such as mining or ranching), or medical services to justify the expense, such facilities are often abandoned. The gradual decay visible in historical satellite imagery supports the theory of abandonment due to disuse over a sudden closure event.

The airport is abandoned. The site, located on a distinct mesa ('Mesa Bonita') just east of the town of Arizpe, still features the clear outline of its dirt runway. However, the runway is completely unmaintained, partially overgrown with vegetation, and shows signs of erosion and informal use by off-road vehicles. There is no remaining aviation infrastructure, such as hangars, lighting, or terminal buildings, on the site.

Mesa Bonita Airport was a small, rural airstrip serving the historic town of Arizpe and the surrounding remote, mountainous region of Sonora. Its primary role was to support general aviation. Operations would have included private flights, air taxi services, support for local ranching and mining industries, and critically, medical evacuation (medevac) flights. Given the challenging terrain and limited road infrastructure in the area, the airport provided a vital link for rapid transportation. It was a basic facility with an unpaved, dirt runway (~4,265 ft / 1,300 m), designed for small, rugged propeller aircraft like Cessna or Piper models. It never handled commercial airline traffic.

There are no known or published plans to reopen Mesa Bonita Airport. The significant cost of refurbishing the runway, meeting modern safety and regulatory standards with Mexico's Federal Civil Aviation Agency (AFAC), and covering ongoing maintenance, combined with the limited economic activity in the immediate area, makes reopening highly unlikely in the foreseeable future. Any such project would require a major new economic driver for the region, such as a large-scale mining operation or a significant tourism development.
