Overview of Aircraft Mortgages and Security Interests
What is an Aircraft Mortgage?
An aircraft mortgage is a security instrument that creates a legal interest in an aircraft to secure the repayment of a financial obligation, typically a loan or credit facility extended for the purchase or lease of the aircraft. It allows the lender (mortgagee) to enforce its rights against the aircraft if the borrower (mortgagor) defaults.
Security Interests in Aviation
Security interests encompass mortgage liens, charges, and other rights over aircraft assets, including engines and parts. They serve as critical risk mitigants for lenders and lessors in a capital-intensive sector, ensuring recovery of loaned capital in default scenarios.
International treaties, such as the Convention on International Interests in Mobile Equipment (Cape Town Convention) and its Aircraft Protocol, play a significant role in harmonizing the recognition and enforcement of these interests globally, a factor both the UAE and Saudi Arabia have addressed in their national legislation.
UAE Law on Aircraft Mortgages: Key Statutes and Regulatory Bodies
Relevant Legal Framework
- Federal Law No. 20 of 1991 concerning the Civil Aviation and the Regulation of Aircraft Registration
- Federal Decree-Law No. 16 of 2021 Regarding Moveable Assets as Collateral for Securing Debt
- The Cape Town Convention (CTC) and its Aircraft Protocol, ratified by the UAE by Federal Decree No. 57 of 2008
- Cabinet Resolution No. 49 of 2021 Implementing the Law on Moveable Assets
- UAE General Civil Aviation Authority (GCAA) as the main regulatory body for aircraft registration and security interest recordation
Core Provisions and 2025 Updates
The UAE aviation security interest regime reflects a convergence of domestic and international rules:
- The GCAA maintains the National Aircraft Registry, which records both aircraft ownership and associated security interests (mortgages and liens).
- Under the 2021 Decree, aircraft constitute moveable property, whose security interests must be registered with the Emirates Moveable Collateral Registry (EMCR).
- Priority of interests is established by registration order, not execution of the agreement.
- New updates for 2025 (pending confirmation as per Ministry of Justice bulletins) are expected to clarify perfection mechanisms and streamline cross-border enforcement processes, particularly for international lessors and financiers.
Practical Application Insights
- It is necessary to dual-register aircraft security interests: (1) with GCAA for recognition against third parties and (2) with the EMCR for priority among competing creditors.
- International interests must, in addition, be registered via the International Registry as per the Cape Town Convention.
- Lenders should review documentation templates to align with the latest statutory requirements to avoid administrative rejection.

Saudi Law on Aircraft Mortgages: Legal Foundations and Recent Developments
Governing Law and Key Institutions
- Saudi Civil Aviation Law (Royal Decree No. M/44 of 2005)
- Implementing Regulations issued by the General Authority of Civil Aviation (GACA)
- Cape Town Convention and the Aircraft Protocol, ratified by Saudi Arabia in 2008
- Saudi Moveables Mortgage Law 2020 (reflecting recent asset-based financing reforms)
Main Provisions and Recent Updates
Saudi Arabia, like the UAE, integrates the Cape Town system with local requirements:
- The GACA Aircraft Register is the official record for registering aircraft mortgages and security interests.
- Saudi Moveables Mortgage Law enables non-possessory security arrangements, broadening the scope for asset-backed lending.
- Registration with the International Registry is mandatory for international enforceability.
- Recent regulations have clarified out-of-court enforcement and streamlined GACA approval for repossession, reflecting best practices in cross-border asset enforcement.
Consultancy Insight: Navigating Compliance in Saudi Arabia
While the process for registering security interests is generally harmonized with international practice, local language requirements, GACA-specific forms, and Sharia principles may necessitate bespoke legal advice. Engaging with local counsel early in the process is essential for navigating these nuances, especially for foreign institutions.
Saudi Legal Update Table: Key Changes in Aircraft Security Interest Legislation
| Aspect | Pre-Cape Town/Early Regime | 2020–2025 Legal Landscape |
|---|---|---|
| Registration Authority | GACA only | GACA + International Registry |
| Scope | Aircraft primarily | Aircraft and engines/ancillary parts |
| Priority | Date of agreement | Date of registration |
| Enforcement | Judicial process (courts) | Enhanced out-of-court enforcement, subject to GACA consent |
Comparative Analysis: UAE Versus Saudi Approaches
Harmonisation and Divergences
Both UAE and Saudi regimes draw heavily from the Cape Town Convention, but there are important distinctions to note.
| Feature | UAE | Saudi Arabia |
|---|---|---|
| Governing Registry | GCAA + EMCR + CTC International Registry | GACA + CTC International Registry |
| Priority Rules | Date of registration in local registry | Date of registration in local registry |
| Dual Registration | Yes (GCAA & EMCR) | No (GACA only, but CTC for international) |
| Enforcement Options | Court and out-of-court enforcement per CTC | Judicial & streamlined out-of-court options |
| Legal Updates Frequency | Regular, proactive reforms | Periodic, driven by sectoral needs |
Practical Tips for Cross-Border Transactions
- Due Diligence: Always verify registration status in both local and international registries before advancing credit or concluding a lease.
- Governing Law Clauses: Carefully draft governing law and jurisdiction clauses, accounting for both UAE/Saudi law and applicable international conventions.
- Documentation Language: Prepare versions in Arabic for government filings in Saudi Arabia and, where needed, in the UAE.
Registration and Perfection: Process Flow and Compliance Checklist
Registration Steps in the UAE
- Draft Security Documentation: Prepare an aircraft mortgage agreement specifying the secured assets, obligations, and enforcement terms as per UAE Civil Code and Decree-Law requirements.
- GCAA Application: Submit mortgage documents and aircraft details to GCAA for notation on the Aircraft Register.
- EMCR Registration: Record interest on the Emirates Moveable Collateral Registry for statutory perfection and priority.
- CTC International Registry: Register interests under the Cape Town Convention for cross-border enforceability.
Registration Steps in Saudi Arabia
- GACA Filing: File mortgage documentation and details (in Arabic) with GACA for recordation on the Aircraft Register.
- Court Attestation (in some cases): Obtain notarial or judicial acknowledgement if required by transaction structure.
- Cape Town Filing: Register with the International Registry.
Suggested Visual: Compliance Checklist Table
| Step | UAE | Saudi Arabia |
|---|---|---|
| Prepare Documentation | English/Arabic | Arabic (sometimes bilingual) |
| Local Registry Application | GCAA, EMCR | GACA |
| International Registry | CTC | CTC |
| Legal Attestation | Not always required | Sometimes required |
Enforcement and Remedies: Default, Repossession, and Dispute Resolution
Enforcement Under UAE Law
Upon default, key enforcement options include:
- Re-possession of the aircraft (subject to GCAA acknowledgment and procedural requirements)
- Judicial sale by public auction under local law
- Assignment of rights or receivership appointment under Civil Code/Decree
The Cape Town Protocol accelerates out-of-court remedies – a significant advantage for international financiers who have registered their interests. For sensitive/global transactions, arbitration may also be invoked for disputes, as recognized in the UAE’s arbitration-friendly legal landscape (see Federal Law No. 6 of 2018 on Arbitration).
Enforcement in Saudi Arabia
Saudi law allows both court-supervised and, post-reform, certain out-of-court enforcement routes (notably self-help remedies if agreed contractually and with GACA’s vetting). However, compliance with Sharia and public order norms is critical; failure to adhere to local requirements may void repossession attempts.
Practical Example: Enforcement Scenario
A UAE-based financier with a registered mortgage over a Saudi-registered aircraft should:
- File a default notice with GACA and the International Registry
- Seek local legal advice to conduct parallel enforcement proceedings, ensuring Sharia compliance
- Pursue out-of-court or expedited court processes as the documentation allows
Risks of Non-Compliance
- Unenforceable security interests if not properly registered
- Loss of priority or subordination to later-registered creditors
- Inability to repossess aircraft due to documentation or procedural errors
- Punitive penalties imposed by GCAA, GACA, or local courts
Risk Management and Compliance Strategies for Businesses
Primary Compliance Challenges
- Complexity of multi-jurisdictional registration
- Interpretation risk due to evolving legislative environment
- Coordination between international lenders, local counsel, and regulatory authorities
Practical Recommendations
- Early Due Diligence: Confirm clean title and absence of prior encumbrances through registry searches
- Legal Documentation Review: Keep all aircraft finance documents updated with new regulatory wording and requirements (especially post-2025 updates)
- Education and Training: Train asset management and compliance teams on new laws and registry procedures
- Ongoing Monitoring: Audit registry entries for continued priority; monitor legal updates via the UAE Federal Legal Gazette and Saudi Ministry of Justice notices
Risk Mitigation Table: Top Risks and Strategies
| Risk | Mitigation Step |
|---|---|
| Incorrect or Delayed Registration | Use standard checklists and specialist legal counsel |
| Jurisdictional Conflicts | Draft contracts with robust choice-of-law clauses |
| Legal Reform Overlooked | Subscribe to regulatory legal bulletins and update compliance manuals regularly |
| Enforcement Blocked | Pre-agree enforcement routes in loan/security documentation |
Case Studies and Practical Scenarios
Case Study 1: UAE-Based Bank Financing a Regional Aircraft Lease
A UAE bank provides financing for a regional carrier operating in both the UAE and Saudi Arabia. Aircraft is registered in the UAE. The bank registers its mortgage with the GCAA, EMCR, and the International Registry.
Issues Encountered:
- Competing creditor claims surfaced due to late registration with EMCR
- Dispute resolved in favour of earliest-registered creditor as per new priority rules
Consultancy Insight:
Timeliness and accuracy in registration with all relevant registries are absolutely critical. Advanced legal review of registry receipts is recommended before disbursal of funds.
Case Study 2: Saudi Lessor Facing Default by a Foreign Airline
Saudi lessor enters a cross-border lease with an international airline. Aircraft is registered in Saudi Arabia; security interest filed with GACA and CTC International Registry.
- Upon lessee default, lessor initiates enforcement proceedings
- Local court upholds mortgage priority, but Sharia-based objections are raised to out-of-court repossession
Consultancy Insight:
Foreign counterparties should structure agreements to provide for both judicial and non-judicial enforcement. Pre-clearance from GACA is recommended prior to initiating any extrajudicial remedies.
Conclusion: Best Practices for Future-Proof Compliance
The legislative environment for aircraft mortgages and security interests in the UAE and Saudi Arabia has never been more sophisticated, globally integrated, or compliance-driven. Ongoing reforms – including the anticipated 2025 updates to UAE’s moveable assets regime – reinforce the necessity for precision, proactive legal risk management, and coordinated cross-border intelligence for businesses and lenders alike.
