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.

2026-13440, 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.
2026-16157, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report indicating that the protection system on the left fan cowl of the right engine does not sufficiently cover the components and systems from possible cross engine debris. This proposed AD would require performing a maintenance records check or inspection of the right engine to determine the part number of the left fan cowl and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
2026-16129, Special Conditions: ATR-GIE Avions de Transport Régional Model ATR42-500 and ATR72-212A Airplanes; Electronic System Security Protection From Unauthorized Internal Access
The FAA is setting new safety rules for ATR42-500 and ATR72-212A airplanes because they have a cool new digital system that lets people inside the plane access its electronics through wireless and wired networks. These rules make sure this tech is just as safe as older systems. The changes kick in on August 7, 2026, and anyone can share their thoughts by September 21, 2026—no extra costs expected.
2026-16159, Revocation of Class E Airspace; Lake Geneva, WI
This action revokes the Class E airspace at Lake Geneva, WI. This action is due to the instrument procedures being cancelled and the closure of the airport.
