Quick Summary
EASA published a new revision of the Easy Access Rules for Continuing Airworthiness (EAR for CAW) on June 2, 2026. This formally incorporates Regulation (EU) 2025/111 — the EU’s continuing airworthiness regulation for electric- and hybrid-propulsion aircraft.
The revision also applies to other non-conventional aircraft, including new air mobility (NAM) vehicles.
This was the first revision to include (EU) 2025/111, which had been deliberately excluded from the September 2025 revision pending its finalization.
The update also refines training requirements for maintenance-certifying staff working on NAM aircraft under Part-66 and is available in PDF, XML, and an enhanced online format via the EASA eRules platform.

What Changed
Regulation (EU) 2025/111 Now Incorporated
The June 2026 revision is the first EAR for CAW to include Regulation (EU) 2025/111, adopted January 23, 2025.
Regulation (EU) 2025/111 amends Regulation (EU) No 1321/2014 to introduce continuing airworthiness rules specifically for:
- Electric-propulsion aircraft
- Hybrid-propulsion aircraft
- Other non-conventional designs — including new air mobility (NAM) aircraft such as eVTOL vehicles
Before this regulation, EU continuing airworthiness rules were designed entirely around conventional combustion-engine aircraft. The introduction of (EU) 2025/111 creates the first formal EU regulatory framework for maintaining, certifying, and managing the continuing airworthiness of aircraft with fundamentally different propulsion architectures.
CS-MCSD Amendments for NAM Aircraft Training
EASA’s ED Decision 2026/001/R, which preceded this revision, amended CS-MCSD (Certification Specifications for Maintenance Certifying Staff Data) to support the implementation of (EU) 2025/111.
The CS-MCSD amendments allow type-certificate applicants for NAM aircraft to use the updated specifications when identifying training requirements for maintenance certifying staff — specifically:
- Type-rating training requirements for engineers certifying maintenance on electric and hybrid aircraft
- Training that is not currently defined in Annex III (Part-66) for these aircraft types
- The basis for developing and approving Part-66 type-rating training courses for NAM aircraft
Key Practical Impact for Part-66 and Part-145
Before this revision:
- No Part-66 type-rating training standard existed for electric or hybrid aircraft
- Part-145 organizations had no standardized continuing airworthiness framework for NAM aircraft
- CAMOs had no regulatory basis for approving NAM aircraft maintenance programs
After this revision:
- The EAR for CAW provides the integrated compliance reference for electric and hybrid aircraft continuing airworthiness
- Part-145 organizations can begin developing NAM-specific maintenance capabilities within a defined regulatory framework
- Part-66 engineers and ATOs have the basis for developing type-rating training courses for specific NAM aircraft types
Why the Revision Was Published
Entry into service of new air mobility aircraft is imminent. Several eVTOL aircraft types — including those from manufacturers like Joby Aviation, Archer, Lilium’s successor programs, and Airbus — are in advanced certification stages with both FAA and EASA. The absence of a continuing airworthiness framework for these aircraft was a critical regulatory gap.
Regulation (EU) 2025/111 was deliberately staged. When the September 2025 EAR for CAW revision was published, EASA noted that (EU) 2025/111 would be included in the next revision. The June 2026 revision fulfills that commitment.
Training standards must precede commercial operations. Without defined Part-66 type-rating training standards for NAM aircraft, operators would have been unable to certify qualified maintenance engineers for aircraft entering service — creating an operational bottleneck regardless of airworthiness certificate status.
Who Is Affected
Part-145 MRO Organizations: MROs planning to establish capabilities for electric, hybrid, or NAM aircraft must now use the June 2026 EAR for CAW as their primary compliance reference. Capability scope expansion applications to national authorities should reference (EU) 2025/111 and the updated EAR.
Continuing Airworthiness Management Organizations (CAMOs): CAMOs that manage or plan to manage NAM aircraft must develop maintenance programs consistent with the June 2026 EAR for CAW. The updated framework gives CAMOs the regulatory basis to seek approval for NAM aircraft maintenance program structures.
Part-66 Licensed Engineers seeking type-ratings on electric or hybrid aircraft now have a regulatory framework for the required training — though specific type-rating courses depend on aircraft type certificate holder training material being developed under the CS-MCSD framework.
Approved Training Organizations (Maintenance — Part-147) ATOs developing training courses for NAM aircraft type ratings must use the CS-MCSD amendments incorporated in this revision as the basis for course design and EASA approval applications.
Type Certificate Holders for NAM Aircraft Manufacturers with EASA type certificate applications for eVTOL and other NAM aircraft must now incorporate (EU) 2025/111 requirements into their Operational Suitability Data (OSD) — specifically the maintenance certifying staff training requirements.
Airlines and Operators Acquiring NAM Aircraft: Any operator planning to acquire and operate electric or hybrid aircraft covered by (EU) 2025/111 must understand the continuing airworthiness obligations applicable to those aircraft from day one of operations.
Compliance Timeline
| Milestone | Date |
|---|---|
| Regulation (EU) 2025/111 adopted | January 23, 2025 |
| ED Decision 2026/001/R — CS-MCSD amendments | February 2026 |
| EAR for CAW September 2025 revision (excludes EU 2025/111) | September 2025 |
| EAR for CAW June 2026 revision (incorporates EU 2025/111) | June 2, 2026 |
| Part-66 type-rating courses for NAM aircraft | To be developed by ATOs using CS-MCSD basis |
| First NAM aircraft entering commercial service (projected) | 2026–2027 |
Operational Impact
Immediate Compliance Reference Update: All Part-145 organizations, CAMOs, and Part-66 practitioners must update their reference documents to the June 2026 revision. The September 2025 revision no longer reflects the complete regulatory position for organizations working with or planning for NAM aircraft.
NAM Capability Development Part-145 organizations wishing to extend capability scope to electric or hybrid aircraft can now formally initiate the process. The regulatory framework exists; the practical pathway is defined.
Training Gap Assessment ATOs and airlines should assess their current Part-66 training catalogue against the new framework. Type-rating training for specific NAM aircraft types will need to be developed as aircraft enter the certification and entry-into-service pipeline.
CAMO Maintenance Program Development: CAMOs acquiring or planning to manage NAM aircraft should begin developing maintenance program structures under (EU) 2025/111 — this work requires lead time relative to aircraft delivery schedules.

Frequently Asked Questions
What is the Easy Access Rules for Continuing Airworthiness?
It is EASA’s primary integrated compliance reference document for all aspects of aircraft continuing airworthiness under Regulation (EU) No 1321/2014 — covering Part-M, Part-145, Part-66, Part-147, Part-ML, and Part-CAO. It is updated regularly to incorporate new regulations and AMC/GM.
What is Regulation (EU) 2025/111?
A Commission Implementing Regulation adopted January 23, 2025, that amends Regulation (EU) No 1321/2014 to introduce continuing airworthiness rules for electric- and hybrid-propulsion aircraft and other non-conventional aircraft. It is the first EU regulation to specifically address the maintenance of new air mobility aircraft.
What are new air mobility (NAM) aircraft?
NAM aircraft include eVTOL (electric vertical take-off and landing) vehicles, electric commuter aircraft, and other aircraft with non-conventional propulsion architectures that fall outside existing Part-66 type-rating categories.
Why was (EU) 2025/111 not in the September 2025 revision?
EASA explicitly stated in the September 2025 revision that (EU) 2025/111 would be included in the next revision, planned for 2026. The June 2, 2026 publication fulfills that commitment.
Where can I access the June 2026 EAR for CAW?
