FAA cybersecurity conditions for Honeywell-modified Boeing 757-200 aircraft
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The rule adds cybersecurity requirements for Boeing 757-200 aircraft modified by Honeywell with a more connected digital systems architecture. The FAA says the existing airworthiness rules do not fully cover the risk that outside network access could reach aircraft electronic systems that were previously isolated. Honeywell and operators using the affected modified aircraft must show that the design protects critical airplane systems from unauthorized external access. The rule is effective June 1, 2026, while the FAA is also accepting public comments until July 16, 2026.

Key Changes
- Adds special FAA safety conditions for Honeywell-modified Boeing 757-200 aircraft with increased external network connectivity
- Requires protection of aircraft electronic systems from unauthorized external access
- Opens a public comment period through July 16, 2026, while making the conditions effective for Honeywell on June 1, 2026
Obligations
What this law requires
Honeywell must ensure the Boeing 757-200 modified digital systems architecture protects airplane electronic systems and assets from unauthorized external access through external network sources.
Honeywell must demonstrate that the modified aircraft design provides a level of safety for electronic system security equivalent to the existing transport-category airplane airworthiness standards.
Operators using Boeing 757-200 aircraft modified under the Honeywell design must maintain the aircraft configuration so that critical airplane systems remain protected from unauthorized external network access.
