FAA Adds Cyber Rules for Luxury Jet Networks

## Summary

The FAA is setting new safety rules for the Dassault Falcon 900EX airplane, upgraded by Honeywell Aerospace, to protect its electronic systems from unauthorized internal access. These rules make sure the plane’s digital networks stay safe and secure, matching modern tech needs. The new standards take effect immediately, and folks can send their thoughts by August 3, 2026.

## Abstract

These special conditions are issued for the Dassault Aviation (Dassault) 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 system that contains a wireless and hardwired network with hosted application functionality that allows access, from sources internal to the airplane, to the airplane's internal electronic components. 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

- Must Secure Falcon 900EX Internal Networks: cost, low. The FAA requires Honeywell’s modification of the Dassault Falcon 900EX to provide isolation or electronic-system security protection from unauthorized sources inside the airplane. The rule is effective June 18, 2026, and it explicitly requires the design to prevent inadvertent or malicious changes…
- Operators Must Follow Continued-Airworthiness Procedures: cost, low. Honeywell must establish procedures so airplane operators can maintain continued airworthiness and keep the approved electronic-system security safeguards in place, including for post-type-certification modifications. The special conditions take effect June 18, 2026, and comments are due by August…
