**SUPPLEMENTARY INFORMATION:**
**History**
An NPRM was published in the *Federal Register* on March 20, 2025 (90 FR 13111) under Docket No. FAA-2025-0466, which proposed to amend 14 CFR part 71 by establishing Class E airspace extending upward from 700 feet above the surface at Wickenburg Municipal Airport, Wickenburg, AZ. Subsequent to publication, new airspace data was received changing the airspace requirements and therefore necessitating a substantial change to the proposed airspace modifications. Therefore, the FAA is withdrawing the NPRM. The FAA anticipates separately issuing a new NPRM to establish the Class E airspace extending upward from 700 feet above the surface at Wickenburg Municipal Airport to support the new instrument procedures being developed.
