The Tenth Circuit Court of Appeals has ruled against Bruce Adams, who operates Southwest Safaris, in his challenge to a ban on commercial air tours over Canyon de Chelly National Monument. The court's decision, filed on October 22, 2026, upholds an Air Tour Management Plan (ATMP) established by the Federal Aviation Administration (FAA) and the National Park Service (NPS). This ruling affects not only Adams and his business but also the cultural and spiritual practices of the Navajo Nation, which holds the monument as sacred.

Adams, who has been conducting air tours in the American Southwest since 1974, argued that his flights did not have a significant impact on the cultural resources of the area. However, the court found that the FAA and NPS had substantial evidence to support their decision to prohibit air tours, citing feedback from the Navajo Nation that indicated such flights intruded on the privacy and cultural practices of the local community.

Background

The dispute began when the FAA and NPS developed the ATMP under the National Parks Air Tour Management Act of 2000 (NPATMA). This act requires federal agencies to create management plans that mitigate the adverse impacts of commercial air tours on national parks and tribal lands. Canyon de Chelly, located in northeastern Arizona, is part of the Navajo Nation and contains numerous culturally significant sites.

After receiving feedback from the Navajo Nation, which overwhelmingly opposed air tours, the agencies proposed an ATMP that would prohibit such flights. The feedback indicated that air tours disturbed residential areas, impacted the serenity of the land, and disrupted cultural and religious practices. Following public meetings and a thorough environmental assessment, the agencies issued a record of decision that concluded air tours would cause significant adverse impacts to the monument's cultural resources.

The Ruling

The Tenth Circuit Court reviewed Adams's petition under the Administrative Procedure Act (APA), which requires the court to determine whether the agencies acted arbitrarily or capriciously. The court found that the agencies had adequately justified their decision to prohibit air tours, stating, "The significant adverse impacts on Tribal lands are primarily due to the invasion of the privacy of the Navajo people." The ruling emphasized that air tours would disrupt traditional cultural practices and ceremonies.

The court also noted that the agencies had engaged extensively with the Navajo Nation, seeking input from various tribal representatives and chapters. This engagement was crucial in determining the impacts of air tours, as the entirety of the monument lies within Navajo tribal trust lands. The court concluded that the agencies' decision was reasonable and well-supported by the evidence presented.

Impact

This ruling has significant implications for the future of air tours over national parks and tribal lands. It underscores the importance of considering the cultural and spiritual significance of these areas when making regulatory decisions. The court's decision affirms the agencies' authority to prohibit air tours if they are found to have significant adverse impacts, thereby reinforcing the protections afforded to tribal lands under NPATMA.

For Adams and other potential air tour operators, this ruling may limit opportunities for commercial flights over culturally sensitive areas. The decision highlights the need for operators to consider the broader implications of their activities on local communities and their cultural practices.

What's Next

Adams has the option to appeal the ruling to the U.S. Supreme Court. However, details regarding any potential appeal or related cases were not available in the court filing. The outcome of this case may influence similar disputes involving air tours and other commercial activities over tribal lands in the future.
