EASA Part-IS and Aviation Compliance: What You Must Know for 2025–2026

As aviation continues its digital transformation, information security is no longer optional—it’s essential. Enter EASA Part-IS: the regulatory framework developed by the European Union Aviation Safety Agency to ensure aviation compliance with cybersecurity and information management requirements.

But what exactly is Part-IS, how does it integrate with existing safety management systems, and what do aviation organisations need to do to prepare?

What is EASA Part-IS?

EASA Part-IS (short for Information Security) is a key regulation requiring aviation organisations to implement an Information Security Management System (ISMS) as part of their wider safety and operational structures.

This means entities such as airports, air carriers, CAMOs, ANSPs, and ATOs must adopt a structured framework to:

– Identify information security risks
– Implement safeguards to protect digital assets
– Ensure incident response, detection, and recovery mechanisms
– Integrate ISMS into their existing Safety Management Systems (SMS)

For full official guidance, EASA has outlined its position in its public documentation here:

Who Must Comply and By When?

The EASA Part-IS regulation is being rolled out in two phases:
– By 16 October 2025: Airports, design organisations, and production organisations must have a fully implemented ISMS in place.
– By 22 February 2026: This applies to AOC holders, CAMOs, ANSPs, ATOs, and other regulated entities.

Delays or failure to meet these deadlines could lead to serious compliance issues and operational consequences.

What is an ISMS in Aviation?

An ISMS (Information Security Management System) is a structured system designed to manage risks related to the information you hold. In the context of aviation, this includes safeguarding data and digital systems that affect aircraft operation, passenger safety, navigation, and communication.

For organisations seeking EASA compliance, your ISMS should:

– Align with international standards like ISO/IEC 27001
– Be scalable to your organisation’s size and risk exposure
– Integrate with your SMS (Safety Management System)
– Be auditable and up-to-date with emerging threats

Understanding the EASA Regulation Structure

The EASA regulation structure includes delegated and implementing acts under the Basic Regulation (EU) 2018/1139. Part-IS is one component within this structure, and it’s designed to complement—not replace—existing safety frameworks like Part-CAMO, Part-145, or Part-ARO.

Understanding where Part-IS fits into your regulatory obligations is key to achieving and maintaining compliance.

Why You Should Act Now

– Avoid penalties: Regulatory oversight will increase as deadlines approach.
– Protect operations: A cyber incident could ground flights or expose critical systems.
– Build trust: Compliance builds confidence with regulators, partners, and passengers.
– Future-proof your business: Aviation is moving toward more connected systems—being secure is now part of being safe.
