Recent theft of non-airworthy turbofan engine parts

Published: 31 March 2026 · Approx. 6-minute read

EASA has now published the exact P/Ns and S/Ns of the stolen parts relating to CFM56-5B, CFM56-7B, V2500, PW1100 and RB211-535E4 applications.^[1] The downloadable attachment published by EASA contains 625 identified P/N-S/N entries.^[2] In broad fleet terms, those engine applications reach into A320 CEO, A320 NEO, Boeing 737NG and Boeing 757 operations, although the attachment itself is an engine-model list rather than an aircraft installation-eligibility document.^[2]

“The stolen parts and equipment as listed in the attachment are to be considered unapproved and not eligible for installation on an aircraft.” ^[1]

What EASA has published

The EASA notification was published on 26 March 2026 under reference OC-EASA-2026002221 and states that the case was reported to the Agency on 17 March 2026 by Spain’s national aviation authority.^[1] EASA’s published attachment, titled Parts List with PN SN and Engine Models, is the core operational document for industry checks.^[2] A count of the published entries shows 265 parts for CFM56-5B, 17 for CFM56-7B, 80 for V2500, 159 for PW1100 and 104 for RB211-535E4, giving a total of 625 listed P/N-S/N entries.^[2]

What happened in Spain

According to EASA, a consignment of formally declared non-airworthy turbofan engine parts was rerouted in Spain in late January 2026 by a third party that allegedly impersonated the contracted mutilation provider.^[1] The shipment consisted of 12 containers of engine parts, three of which contained Critical or Life-Limited Parts that had not been mutilated.^[1] EASA says law-enforcement agencies are investigating the case, but the public notice does not identify suspects, does not give a more precise site than Spain, and does not give a more precise theft date than “late January 2026”.^[1]

Why this matters beyond one theft

This case matters not only because of the theft itself, but because it tests whether organisations already have a functioning forbidden-parts or blocked-parts control. EASA says owners, operators and maintenance organisations should inspect aircraft and inventories for the listed part numbers and corresponding serial numbers and, if found, remove and quarantine the parts and inform the competent authority.^[1] The wider control question is whether that same logic exists before the next alert appears: is the list driven only by ADs, or is it also fed by EASA SUP notifications, authority alerts, OEM instructions, shop findings, internal reports and contract-driven restrictions such as lease requirements?^[3]

EASA’s background page explains that unresolved SUP cases are published to raise awareness across the European aviation industry and that the published list is maintained and updated based on available information and responses received from industry.^[3] EASA SIB 2017-13R1 adds a practical warning that unlawfully removed parts may later appear on the market with forged documentation or untraceable history, and recommends consulting the EASA SUP information before accepting a part or fitting it to an aircraft.^[4]

Identification, segregation and mutilation

The EASA control framework is clear on the fundamentals. EASA guidance says the unserviceable status of a component should be clearly declared on a tag together with the component identification data and any information useful to define the necessary actions.^[5] For unsalvageable components, EASA guidance says mutilation should make the component permanently unusable for its originally intended use and should prevent it from being reworked or camouflaged to provide the appearance of being serviceable.^[5] The current case demonstrates exactly why those controls exist.

FAA guidance points in the same direction. AC 20-154A says receiving and inspection systems should help prevent the introduction of unairworthy parts into inventories and notes that life-limited parts, when sold or transferred, must include the mark, tag or other record used to comply with 14 CFR 43.10.^[6] FAA guidance on life-limited parts also highlights the importance of current life status and supporting traceability.^[6] FAA AC 21-38, which addresses unsalvageable aircraft parts and materials, says mutilation should prevent such items from being sold as serviceable parts and refers suspected unapproved parts for reporting through FAA Form 8120-11 or the FAA Hotline.^[7]

SUP handling and reporting

For EASA organisations, suspected unapproved parts handling should sit inside a smooth internal reporting route, linked to occurrence reporting and the Safety Management System. EASA SIB 2017-13R1 links the SUP framework to Article 4(4) of Regulation (EU) No 376/2014 and to Commission Implementing Regulation (EU) 2015/1018, which includes “the use of products, components or materials, from unknown, suspect origin, or unserviceable critical components” among reportable occurrences.^[4] In practical terms, teams should know how to identify a suspect part, quarantine it, escalate the case, preserve the evidence trail and report through the correct authority channel without delay.

The FAA applies a similarly structured reporting logic. The FAA SUP Program says the agency investigates every SUP report and invites reporting through the FAA Hotline or FAA Form 8120-11, while AC 21-29D describes that form as the standardised means of reporting.^[8] That is particularly relevant for organisations operating in mixed regulatory environments or dealing with suppliers, repair stations and inventories that touch both EASA and FAA systems.

Supporting note on release-document awareness

Alongside the immediate stock, quarantine and reporting actions, organisations may also wish to review whether their internal spare-parts procedures clearly address cross-border release-document requirements where these arise. EASA notes that its component-release table is only a reference tool. Final acceptance always depends on the applicable regulation or bilateral agreement, such as the EU-US TIP or MAG, which set the detailed conditions.^[9] EASA’s FAQ on the EU-US bilateral framework says a dual release is required for acceptance of used engine/components from a U.S.-based repair station, subject to the detailed conditions stated by EASA.^[10] The FAA’s Technical Implementation Procedures for Airworthiness and Environmental Certification explain that the TIP covers design approvals, production activities, export airworthiness approvals and technical support between the United States and the European Union.^[11]

The same principle extends beyond the EU-US framework. The UK CAA publishes component-acceptability tables for new and used / maintained components and explicitly says they should be read against the latest bilateral agreement or working arrangement.^[12] EASA’s own reference material lists ANAC Form F-100-01 in the applicable bilateral cases, and CAAC’s CCAR-145 requires used material to come with Form AAC-038 issued by an approved maintenance organisation within its system.^[9]^[13] If an aircraft is leased, the operator should also confirm that lessor or lease-management documentary requirements are aligned with the receiving and installation decision.

What organisations should review now

Immediate check of aircraft, records and inventory against the published EASA P/N-S/N list.
Immediate quarantine and escalation route for any match or suspect match.
Review of the forbidden-parts / blocked-parts process, including its feeding sources and update ownership.
Review of approved supplier and approved MRO controls, including notification of this event where relevant.
Verification that the receiving-inspection process captures traceability, life status and release-document checks.
Targeted awareness for stores, procurement, logistics, technical records, planning, workshops and certifying staff.
Consideration of an internal Safety Bulletin so the organisation reacts consistently, not only at stores level.

Current investigation status and likely motive

On the current public record, the investigation is still at an early visible stage. EASA says law-enforcement agencies are investigating, but no suspects have been named publicly and no official motive has been published.^[1] The clearest immediate risk described by EASA is illicit resale into the open market.^[1] Recent trade coverage has also framed the case against wider aftermarket integrity concerns and tight legitimate-parts availability.^[14] Reuters reported in October 2025 that severe shortages of next-generation engines had, in some cases, flipped market economics so that engines were worth more as spares than the aircraft they powered.^[15] That does not prove motive in this case, but it does show why the market environment can create incentives for fraud, illicit resale and document abuse.

Conclusion

The lesson from this event is operationally simple but organisationally demanding: a published stolen-parts list is useful only if it is connected to receiving inspection, supplier control, inventory segregation, installation decision-making, reporting, and staff awareness across the whole organisation. A forbidden-parts control that exists only in one person’s spreadsheet is not a resilient control.

Global Aero Services A&C can support operators, CAMOs, lessors and MRO stakeholders with independent review of spare-parts internal procedures, SUP handling arrangements and practical improvement actions.
