FAA Issues Hack-Proof Rules for Falcon 900EX Jet

## 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.

## Abstract

These special conditions are issued for the Dassault Aviation Model Falcon 900EX airplane. This airplane, as modified by Honeywell Aerospace US LLC (Honeywell) will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is the installation of a digital systems architecture that will allow increased connectivity to and access from external network sources, (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the airplane's previously isolated electronic assets (networks, systems, and databases). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

## Effects PRIA read

- New Aircraft Cybersecurity Requirements: cost, medium. 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…
- Operator Procedures for Continued Airworthiness: cost, low. 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 throu…
- Applies Only to Falcon 900EX Honeywell Mod: mixed, low. 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 a…
