Onavas Airport

The closure was most likely due to a combination of economic factors and obsolescence. Small, rural airstrips like Onavas were often built to serve remote communities before reliable road infrastructure was established. As the local road network improved, the need for a dedicated airstrip with its associated maintenance costs diminished. The low volume of traffic would have made it economically unviable to maintain and operate. There is no evidence to suggest it was closed due to a specific accident, military conversion, or environmental concerns.

The airport is abandoned and permanently closed. The physical site still exists, and the outline of the single dirt runway (approximately 1,200 meters / 3,900 feet) is clearly visible from satellite imagery. However, the runway is unmaintained, overgrown with vegetation, and has large white 'X's painted at each end to signify its closed status to any pilots overflying the area. There are no buildings, hangars, or other aviation infrastructure remaining on the site. The land appears unused, though tracks suggest occasional use by ground vehicles.

Onavas Airport (also known as Aeródromo de Onavas) was a small, unpaved airstrip that served the remote municipality of Onavas in Sonora. It never supported scheduled commercial airline service. Its operations were limited to general aviation, which would have included:
- **Private Flights:** Used by local landowners or business interests.
- **Air Taxi/Charter:** Providing on-demand transport to larger cities like Hermosillo or Ciudad Obregón.
- **Government/Medical Services:** Facilitating access for medical emergencies or government officials to the remote area.
- **Agricultural Aviation:** Potentially used for crop dusting or other agricultural support activities, given the region's economy.
Its primary significance was providing a vital transportation link for a community that was otherwise relatively isolated.

There are no known or published plans to reopen Onavas Airport. Given the small population of the municipality, the existence of adequate road transportation, and the significant cost required to rehabilitate the runway and bring it up to modern safety standards, the prospect of it ever reopening for aviation purposes is extremely low.
