FAA shields planes from crew hacking via internal networks?!

## Summary

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.

## Abstract

These special conditions are issued for the ATR-GIE Avions de Transport R[eacute]gional (ATR) Model ATR42-500 and ATR72-212A airplanes. These airplanes 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

- Cybersecurity Requirements for ATR42/ATR72: benefit, medium. The FAA requires new cybersecurity protections for ATR Model ATR42-500 and ATR72-212A airplanes effective August 7, 2026. The design must prevent unauthorized internal access and stop inadvertent or malicious changes to systems required for safe flight, protecting the confidentiality, integrity, an…
- Operator and Applicant Security Procedure Duties: cost, low. ATR (the applicant) must design isolation or electronic-system security protections and establish procedures so operators can maintain those safeguards, including for post-type-certification modifications. This requirement is effective August 7, 2026, with comments due September 21, 2026; the FAA s…
