2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.

The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.

2026-15602, Amendment of Jet Route J-24 and Very High Frequency Omnidirectional Range Federal Airways V-244, V-508 and Revocation of Very High Frequency Omnidirectional Range Federal Airway V-255 in the Vicinity of Hays, Kansas.
This action proposes to amend Jet Route J-24 and Very High Frequency Omnidirectional Range Federal (VOR) Airways V-244 and V-508 and revoke VOR Federal Airway V-255 in the vicinity of Hays, Kansas. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Hays, KS, VOR/Tactical Air Navigation (VORTAC) navigational aid (NAVAID). The VOR portion of this NAVAID is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program. The TACAN portion of this NAVAID will be retained.
2026-15532, Airworthiness Directives; CFM International, S.A. Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2018-26-01, which applies to all CFM International, S.A. (CFM) Model CFM56-7B engines. AD 2018-26-01 requires initial and repetitive ultrasonic inspections or eddy current inspections of certain fan blades for crack indications and, depending on the results of the inspections, replacement with parts eligible for installation. Since the FAA issued AD 2018-26-01, CFM issued updated service material providing improvements to the ultrasonic inspection procedures and expanding the inspection area. This proposed AD would require initial and repetitive ultrasonic inspections or eddy current inspections of certain fan blades for crack indications and, depending on the results of the inspections, replacement with parts eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
