Notice of Proposed Rulemaking (NPRM) - Amendment of Class D Airspace for Chandler (KCHD) and Phoenix-Mesa Gateway (KIWA) Airports – Comments Due Monday, 2 February 2026
As many of you may already know, the FAA has issued an NPRM to amend the Class D airspace for both KCHD and KIWA. This proposed rulemaking is the result of “biennial airspace reviews intended to support instrument flight rule operations and to ensure compliance with agency orders.”
For KIWA – the Class D radius would increase from 5 miles to 5.4 miles. The proposal includes adding exclusion areas for KCHD and Pegasus Airpark.
For KCHD – the Class D airspace radius would increase from 4 to 4.8 miles. The vertical limit would increase from 3,000 to 3,700 feet. The KIWA exclusion area would be removed as it is no longer required.
The FAA also intends to establish Class E airspace extending upward from 700 feet above the surface for both Stellar Airpark and Mesa Gateway Airport. For Stellar Airpark, this would encompass a 13.9-mile radius. For Mesa Gateway, the Class E area would include a 7.9-mile radius and specific extensions to the southeast to accommodate aircraft approaches.

Those of you that are based at P19, Pegasus, KFFZ, KCHD and KIWA or fly in the vicinity of these airports know that it is very congested airspace and these proposed changes will introduce significant safety concerns. As an example, there is a significant volume of traffic that utilizes the corridor from KFFZ to KCHD for transition around the Phoenix Class B and to access the south practice areas. The NPRM would decrease the vertical space between the Phoenix Class B and KCHD Class D to just 300 feet, increasing the potential for conflicts and midair collisions. There are many others.
APA will be submitting comments opposing this NPRM, and we urge individual pilots to submit comments prior to the 2 February deadline.
