FAA Grounds Boeing 787s Over Sketchy Engine Rules
Published Date: 9/29/2026
Rule
Summary
The FAA is making a new rule for certain Boeing 787-8 and 787-9 airplanes to keep flights safe. It stops airlines from flying planes under a specific equipment rule that lacks proof the engines will work properly. This rule starts October 14, 2026, and airlines need to follow it to avoid safety risks, with comments open until November 13, 2026.

Boeing 787 operators banned from MMEL dispatch
If you operate Boeing 787-8 or 787-9 airplanes equipped with the listed Rolls‑Royce Trent 1000 engines, you may not dispatch the airplane under your minimum equipment list item corresponding to MMEL item 75-33-01 as of 60 days after the AD's effective date (effective date October 14, 2026; prohibition effective 60 days later). MMEL item 75-33-01 previously allowed dispatch for three days with one intermediate pressure bleed valve (IPBV) inoperative. The FAA estimates this AD affects 16 U.S.-registered airplanes and will cost about $85 per airplane (1 work-hour), $1,360 total for U.S. operators.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
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.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
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.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.

The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.

The FAA is getting ready to update its environmental review for SpaceX’s plan to launch and land up to 76 Starship-Super Heavy rockets each year at Cape Canaveral. This means more rocket action with up to 152 landings annually, including some right back at the launch site or in the ocean. The public can share their thoughts by October 14, 2026, helping shape the final plan that balances space excitement with environmental care.
