FAA Issues Hack-Proof Rules for Falcon 900EX Jet
Published Date: 6/18/2026
Rule
Summary
Honeywell Aerospace is upgrading the Dassault Falcon 900EX with new digital systems that connect the plane to outside networks like the internet and wireless devices. Because this is a new kind of tech for airplanes, the FAA is setting special safety rules to keep hackers out and protect the plane’s electronics. These rules take effect June 18, 2026, and Honeywell must follow them to keep flights safe without extra costs for passengers.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 2 costs, 1 mixed.
New Aircraft Cybersecurity Requirements
The FAA requires Honeywell to protect the Dassault Falcon 900EX's electronic systems from unauthorized external access, including access that could occur during maintenance. The rule requires identifying and assessing electronic-system security threats and implementing protection strategies so the airplane's safety, functionality, and continued airworthiness are not compromised.
Operator Procedures for Continued Airworthiness
Honeywell must establish procedures so the airplane operator can maintain electronic-system safeguards and continued airworthiness, including after post-type-certification modifications that affect those safeguards. These procedures are intended to ensure security protections remain effective throughout the aircraft's service life.
Applies Only to Falcon 900EX Honeywell Mod
These special conditions apply to the Dassault Aviation Model Falcon 900EX airplane as modified by Honeywell. The Falcon 900EX is a three-engine transport airplane with a maximum takeoff weight of 48,300 to 49,000 pounds and a maximum passenger capacity of 19 persons; the special conditions would also apply to other models on the same type certificate if Honeywell later applies to modify them.

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.
2026-19343, Airworthiness Directives; Leonardo S.p.a. Helicopters
If you own or maintain Leonardo AB139 or AW139 helicopters, the FAA wants you to update your maintenance rules with new safety limits to keep flying safe. This replaces an older rule and means you’ll need to revise your maintenance manuals soon. Comments on this change are open until November 6, 2026, so get ready to act and keep those choppers in top shape!
2026-19345, Airworthiness Directives; Bell Textron Canada Limited Helicopters
If you own or operate Bell Textron Canada Model 429 helicopters, heads up! The FAA wants you to check the sliding door’s lower roller parts for damage and fix any issues to stop doors from jamming. You’ll also need to update the roller setup soon, with comments on this rule due by November 6, 2026. This keeps your chopper safe without breaking the bank.
