AWG was created to contribute to, and was a central participant in, the development of the Cape Town Convention (CTC).
CTC is a treaty designed to facilitate asset-based financing and leasing of aviation equipment, expand financing opportunities, and reduce costs – thereby providing substantial economic benefits.
CTC does so by reducing a creditor’s risk and by enhancing legal predictability in these transactions, including in the case of a debtor’s insolvency or other default.
CTC entered into force in 2006, and the final texts of the Convention and Protocol can be viewed on UNIDROIT’S website. CTC applies in countries (contracting states) that have ratified or acceded to it.
AWG’s major work on the Cape Town Convention can be organized as follows:
- Resource materials on the Cape Town Convention
- Ratification and implementation of the Cape Town Convention
- Compliance with the Cape Town Convention
- Economics of the Cape Town Convention
- International registry under the Cape Town Convention
Resource materials on the Cape Town Convention
AWG publishes major suite of resource materials on the Cape Town Convention and its Aircraft Protocol to aid courts, Civil Aviation Authorities, practitioners, academics, and all others using or interpreting CTC
The following documents have been produced by its Legal Advisory Panel:
| Principles-Based Guide to the Official Commentary | Aids in identifying relevant authority in the authoritative Official Commentary 5th (OC) relating to the most frequently encountered questions from a transactional perspective arising in the application and interpretation of CTC. Sets out a topical index to the OC in the form of main principles found in or underlying the texts, which are also summarized, and links such principles to specific paragraphs in the OC. Does not seek to modify or interpret the OC and is intended as a practical companion to the OC. It is recommended that all who use this guide do so with a written or electronic copy of the OC in close proximity. The guide and master citation document should be saved into the same location on your computer in order to see the full functionality for the hyperlinks. |
| Civil Aviation Authorities’ Guide | Assists civil aviation authorities in the interpretation and implementation of, and compliance with, CTC provisions and requirements. Summarizes and applies main CTC provisions related to de-registration of an aircraft from its state of registry and export of aircraft objects from where they are situated. Addresses link between the CTC international registry and national designated entry points, where applicable. |
| Judicial Guide | Assists judges dealing with the application of CTC in their national courts and practitioners preparing pleadings in disputes before their national courts where CTC is relevant. |
| Practitioners’ Guide | Provides a summary of CTC basics and practical information for those entering into or advising on transactions governed by CTC. Contains detailed discussion on common and complex issues which have arisen over time. Includes key appendices addressing important items such as CTC legal opinions and a checklist for CTC remedies. |

Ratification and implementation
Status of ratification
The status of those countries that have ratified the Cape Town Convention and its Aircraft Protocol is maintained by UNIDROIT, the legal depositary of these instruments.
AWG work on ratification
AWG is committed to the global ratification of the Cape Town Convention. It consults with governments around the world on ratification, including on the declarations to be made and the relationship between the Cape Town Convention and national law.
For complete and official information relating to ratification and declarations, see materials published by UNIDROIT.
AWG work on implementation
For ratification of the treaty to have meaningful legal and economic effect, its terms, together with the declarations made, must prevail over conflicting law in contracting states.
AWG consults with governments on ensuring that, in theory and practice, the treaty so prevail. We refer to this as the ‘primacy’ of the Cape Town Convention.
Primacy is required by international law: article 27 of the Vienna Convention on Treaties prevents the assertion of national law reason for treaty non-compliance.
Declarations under the Cape Town Convention
The Cape Town Convention (CTC) is not a treaty that a country simply decides to ratify or not. Rather, a number of choices need to be made at the time of ratification. These choices – declarations – are an integral part of the treaty system.
Most importantly, certain declarations are specifically designed to reduce transaction risk, and, thus, produce economic benefits. These declarations have been identified in the OECD Aircraft Sector Understanding (ASU) as qualifying declarations.
AWG also encourages all countries to ensure that any declaration under Convention Article 39 restricts preferred non-consensual liens / rights to those that are customary. In no event (as prevented by the treaty) may such a declaration purport to expand such liens / rights beyond those under current law. See Goode, Official Commentary, 4th Edition at paras 2.263-2.264, 2.269, and 4.279.
Making the qualifying declarations
In order to have the full economic benefits, a country must:
- make the qualifying declarations under the OECD Aircraft Sector Understanding,
- assure the Cape Town Convention has the force of law, and,
- to the extent of any conflict, prevails over other law in such country.
The qualifying declarations can be found under the OECD Aircraft Sector Understanding at the OECD’s website.
Ratification materials developed by AWG
AWG prepared a document relating to the ratification and implementation of the Cape Town Convention.
This includes a short-form of model legislation relating to the ratification and accession implementation of CTC.
This short-form legislation includes:
- declarations under the CTC
- regulations relating to the deregistration and export under an IDERA
- court rules relating to judicial procedures under CTC
- procedures for exercising possessory related non-judicial remedies under CTC
AWG has produced the stand-alone short-form model of IDERA regulation annotated version where a contracting state has made a declaration applying article XIII of the protocol. This document includes an annotated version of the model form with explanatory comments.
European Member States and the EU
Competence between the EU and Member States is divided as regards the Cape Town Convention. Therefore, special care is required when EU Member States make declarations. EU Member States would need to give effect to this article through national law.
UNIDROIT has issued a seminar report on that matter. Annex III of the report summarizes the key conclusions regarding declarations within the competence of Member States and the EU respectively. These conclusions are consistent with a special clause, article 4, in the ASU qualifying declarations.
AWG representatives have written a paper, ‘‘Cape Town Treaty in the European Context: the Case for Alternative A, Article XI of the Aircraft Protocol‘. In line with the above-mentioned competence rules, EU Member States would need to give effect to this article through national law.
Cross-border application of article XI of the Aircraft Protocol where airline’s centre of main interest is in an EU member state
On 11 May 2021, the Cape Town Convention Academic Project published an exchange of letters with Sir Roy Goode on the cross border application of Article XI of the Aircraft Protocol where the airline’s centre of main interest is in a Member State of the European Union.
Compliance with the Cape Town Convention
Effective compliance
Compliance with CTC means that a contacting state:
- takes all action to ensure that CTC has the force of national law with priority over any conflicting law (effective implementation)
- fully and accurately applies the operative terms of CTC to actions and disputes within its scope, whether administratively or judicially
In other words, a contracting state complies with CTC when the treaty legally applies, and is fully and accurately applied, to matters within its scope.
AWG work on compliance
AWG works on state compliance with CTC in three ways:
- promoting incentives to comply (though index scoring and eligibility for export credit discounts)
- preventing non-compliance (through education and information)
- acting to address non-compliance (for AWG members only)
For incentives, see corresponding section.
For prevention, see corresponding section.
For action, AWG consults with governments and intervenes in administrative and legal proceedings on behalf of its members when so requested by its members.
AWG also establishes coordinated compliance action groups to seek compliance in large scale insolvency or insolvency type events to which the cape town convention applies and which involve our members.
The following chart depicts our approach to compliance:
Incentive: Cape Town Convention compliance index
AWG released the inaugural edition of the CTC compliance index on 29 February 2020.
AWG releases its semi-annual updates in April and October, see Cape Town Compliance Index for most up to date scores.
The Cape Town Convention Compliance Index (CTC compliance index) monitors and assesses compliance by contracting states with their undertakings under CTC.
The CTC compliance index is hosted on a separate platform, which can be found here. Visit the CTC compliance index platform for all information on the CTC compliance index.
Subscription information on the CTC compliance index can be found here.
Several of AWG’s historical projects reporting on implementation have merged into this project, including its past work on summaries of national implementation for contracting states. A parallel and equally significant goal of the CTC compliance index is to incentivize future compliance by providing accurate, timely information to stakeholders, including the OECD, and communicating concrete proposals for improving compliance in the applicable contracting state.
AWG works with over 250 law firms worldwide, including our established network of national contact groups, to obtain all compliance-related data and experience. Such data and experience are then analyzed by the AWG secretariat. AWG’s legal advisory panel reviews proposed scoring, and a final determination on scoring based on legal facts is made by the AWG secretariat without regard to political or economic considerations.
CTC compliance index watchlist notices
CTC compliance watchlist notices (‘watchlist notices) are issued to indicate that AWG has become aware of material developments in a contracting state that may affect the score but has not yet completed its assessment of the impact of such material developments. Watchlist notices provide an outlook on scoring with reference to the contracting state’s existing score rather than CTC compliance per se. For example, where the affected variable is low in a contracting state, a further non-compliant development will be assigned a ‘confirmatory’ outlook. Once a contracting state is placed on the CTC Compliance Watchlist, AWG will closely monitor ongoing developments and issue reports on a regular basis with fact-based, events-driven updates.
Note on the interpretation of watchlist notices issued on the Index can be found here.
Visit the CTC compliance index website for more information.
Coordinated compliance action groups
AWG creates coordinated compliance action groups (CCAG) when faced with an actual or anticipated airline insolvency or other non-performance in a contracting state.
A CCAG supports AWG submissions and interventions, serves as an information center, assists in contacting local government officials, and helps develop timely updates on the CTC compliance index.
Interventions
AWG may, depending on facts and circumstances, seek to intervene, as a friend of the court in legal proceedings or with insolvency administrators or administrative authorities seeking compliance with CTC. We only do so for our members. We limit our interventions to seeking compliance with the requirements of the treaty.
AWG has recently submitted compliance-related papers in Australia, Brazil, Colombia, Ireland, India, Luxembourg, Malaysia, Mexico, Norway, Nigeria, Russia, Singapore, South Africa, Sweden, Turkey, United Kingdom, and the United States.
Working relations
AWG has long-standing working relations and formal status with a wide range of governments, intergovernmental bodies, industry groups, and academic institutions, and policy groups.
Prevention of non-compliance: educational materials, educational outreach and events
AWG actively engages and interacts with contracting states, seeking compliance, through educational resources and informational events. AWG provides state of the art educational materials on CTC topics and holds regional events worldwide.
AWG releases model court rules for disputes governed by the Cape Town Convention
AWG releases model court rules for disputes governed by the Cape Town Convention. These are available for adoption by the highest court or other regulators in Contracting States. They may take the form of binding court rules, regulations, circulars, or practice directives. They are attached in word.
The model court rules have been endorsed by the executive committee of AWG’s legal advisory panel.
The model court rules set out key procedural items required for compliance with the convention and its aircraft protocol.
Independent expert opinion concerning the application of CTC under Chapter 11 of the US Bankruptcy code involving a non-US debtor
An independent expert opinion has been issued on the application of CTC under Chapter 11 of the US Bankruptcy code involving a non-US debtor.
It concludes that the courts of the United States, including courts having jurisdiction over a non-US Airline Chapter 11 bankruptcy case (or over any other case under the Bankruptcy Code), are obligated to apply Protocol Article XI Alternative A in conformity with the declaration made by the State which is that airline’s primary insolvency jurisdiction (where its center of main interests are situated and whether or not insolvency proceedings are under way in that State) without further legislation or implementation by the United States.
The independent expert opinion may only be used in full, as its must be read as a whole.
Assessment of CTC and schemes of arrangements in the insolvency context
An expert opinion has been issued on CTC and restructuring plans and schemes of arrangements in the insolvency context.
It concludes that schemes of arrangement proceedings in the insolvency context are ‘insolvency proceedings’ for purposes of the Cape Town Convention. Thus, modification of a CTC creditor’s rights without its consent is not permitted in such proceedings – where the debtor’s main place of business is in a CTC state which declared or incorporated Alternative A (remedies on insolvency). The foregoing is without prejudice to actions taken in connection with a CTC compliant scheme, which includes providing each CTC creditor with a termination option.
The expert opinion may only be used in full, as its must be read as a whole.
Educational materials
Self-instructional materials
AWG with the support of the panel, has prepared comprehensive self-instructional materials for individuals needing information about the Cape Town Convention (CTC).
These “self-instructional materials” have been assembled in the context of the Cape Town Convention academic project (CTCAP), and seek to assist scholars, students, practicing lawyers, judges and other government officials, as well as the industry at large, by providing information on and education about the CTC.
These self-instructional materials have been translated by the panel into:
Judges manual handbook
AWG with the support of the legal advisory will develop a judge’s handbook to assist judges, government officials, and litigation lawyers by setting out the requirements of the treaty in contested cases. Subject to needed approvals, it is planned to have the handbook issued, and kept current, as a document issued by the CTC academic project.
The practitioner’s guide
AWG with the support of the Legal Advisory Panel has published the 2023 edition of the Practitioners’ Guide. It is designed to provide practical assistance to practitioners in working with the Cape Town Convention (CTC):
Cape Town Convention Academic Project
A pillar of AWG’s education work on the cape town convention, including compliance, is through the Cape Town Convention Academic Project. (CTCAP).
The CTCAP is undertaken under the joint auspices with the University of Cambridge and UNIDROIT.
The CTCAP operates within the Cambridge Faculty of Law through the Centre for Corporate and Commercial Law.
The CTCAP provides for academic study and assessment of the Cape Town Convention, seeking to advance the understanding and effective implementation of, and compliance with, the treaty.
The CTCAP will be strengthened by the inclusion of related joint projects on:
(1) economic assessment of international commercial law reform, and
(2) best practices in the design and operation of electronic registries.
AWG is the founding sponsor of CTCAP. Its secretary general, acting in his academic capacity, co-directs the project with, professor Louise Gullifer, Cambridge, and Ignacio Tirado, secretary general of UNIDROIT. Sir Roy Goode (emeritus professor, Oxford) and Rob Cowan (managing director, Aviareto) are senior advisers to the CTCAP.
The project advances its purpose by reporting on and providing analysis of cases and administrative actions designed to assist in the proper interpretation and compliance with CTC. It develops academic and educational materials.
The project holds a major yearly academic conference. It is widely considered the leading cape town convention related event. Its hosts a mix of leading academics, professions, government officials, and industry leaders in detailed assessment of treaty issues.
The project publishes the CTC journal, linked to the above conferences. It is open access, available on-line and at no cost.
The CTCAP website can be viewed at www.ctcap.org.
Cape Town Convention international moot court program created
Cape Town Convention academic project (CTCAP) has created the Cape Town Convention (CTC) international moot court program (CTC moot court).
The purpose of the CTC moot court is to familiarize students and judges with CTC in the context of complex hypothetical fact patterns and to provide students with educational exercises involving these instruments in a simulated judicial setting.
Upcoming CTC moot courts
The next CTC moot court, involving students from Brooklyn and Fordham Schools of Law, will take place on 2 April 2025 at Brooklyn University.
Training materials for the CTC moot court can be found here.
Other CTC moot courts are being organized.

CTC economics
Economic assessment of the Cape Town Convention
AWG makes significant efforts, including through its commissioning of third-party experts, to assess and quantify the economic benefits of CTC.
AWG continues to work closely with governments around the world in assessing the economic benefits of CTC.
Historic documents
In 1988, a first economic impact assessment was prepared under the joint auspices of New York University and INSEAD (Paris). That document was commissioned by AWG, IATA, and ICAO, and helped guide the development of the treaty.
In 2009, AWG commissioned an updated independent study addressing the economic benefits of the Cape Town Convention. The new study was narrower in scope. It focused exclusively on airline benefits and strictly assumed application of the insolvency rule found in Protocol, Art. XI, Alternative A.
In December 2010, AWG commissioned an independent study assessing the economic benefits of the ratification of the Cape Town Convention in the United Kingdom.
These studies have confirmed the substantial and widely shared economic benefits of ratification and effective implementation of the Cape Town Convention. Such benefits are predicated on a Contracting State making a specific set of economically-oriented declarations, that is, the ASU qualifying declarations, and ensuring that the Cape Town Convention prevails over inconsistent national law.
AWG has submitted, or materially contributed to submissions of, several other economic assessment for individual governments, but has elected not to make these public, given commercial information.
Academic work on economic assessment
AWG’s work on assessing the economic benefits of CTC is strengthen by academic work that assesses the economics of broader context of international commercial law reform.
This project is undertaken under the joint auspices with the University of Cambridge and UNIDROIT. These institutions carry the project forward from, and further develop the pioneering work by, the Universities of Oxford and Washington. AWG’s secretary general, acting in his academic capacity, directs the project.
The fourth workshop on best practices in the field of electronic registry design and operation took place in Rome at the headquarters of UNIDROIT on 9 September 2020.
The sixth workshop on economic assessment of international commercial law took place in Rome at the headquarters of UNIDROIT on 8 September 2020.
The official website of the project and its details can be consulted at https://www.law.ox.ac.uk/research-subject-groups/economic-assessment-international-commercial-law-reform
Export credit and the Cape Town Convention
The OECD Aircraft Sector Understanding (ASU) establishes the basic rules for the provision of export credit.
On 1 February 2011, the current ASU (the 2011 ASU) entered into force. The 2011 ASU, like its predecessor 2007 version, permits a reduced fee or interest rate (as applicable) where CTC applies to a transaction. Under the 2011 ASU, the maximum Cape Town discount is 10% off the otherwise applicable upfront fee or per annum spread.
The Cape Town discount endorses the long-standing view of AWG that application of CTC reduces transaction risk, and, thus, should be reflected in the terms of credit.
The 2011 ASU permits a Cape Town discount provided that a set of qualifying declarations has been made and CTC is effectively implemented in national law and the country complies with its treaty obligations.
Assessing eligibility to the ASU CTC discount
AWG assesses whether a country meets the standards set out in the ASU for eligibility for the Cape Town discount under the 2011 ASU. It produces and maintains a country-by-country listing of that assessment, based on data and inferences from the relevant parts of CTC compliance index. The AWG assessment is independent of the OECD (and its participants) and their decision-making on eligibility for the CTC discount under the ASU. It assesses the substantive ASU standard without reference to whether a country is on the ‘Cape Town list’, as defined in the ASU.
AWG has held productive consultations with the OECD since 2018 relating to discretionary and non-exclusive use of CTC compliance index by the OECD in connection with OECD decision-making on eligibility for the CTC discount.
The International Registry
The Cape Town Convention (CTC) established an electronic registry (International Registry) which facilitates the online registration of interests in airframes, engines and helicopters. The International Registry is an integral part of CTC. Aviareto was appointed to run the International Registry by ICAO in 2006.
AWG chairs the International Registry Advisory Board (IRAB) which provides advice to the registrar on matters relating to the needs of users, in connection with the operations of the International Registry. AWG also serves as an observer to the Commission of Experts of the Supervisory Authority of the International Registry (CESAIR), that provides advice to ICAO, the supervisory authority.
Supplementing the terms of the CTC, use of the International Registry is subject to regulations and procedures issued by the supervisory authority. The current edition of the regulations and procedures can be found here.
The most recent annual report issued by Aviareto can be viewed here. General educational videos prepared by Aviareto relating to the International Registry are linked here.
Many changes have been made to the International Registry since 2006 to streamline the functionality for making registrations. Development is currently taking place on generation 3 of the International Registry.
In January 2019, the International Registry celebrated a significant milestone when it reached 1 million registrations.
Academic work on electronic registry best practices
AWG’s work on best practices relating to the registrations with the International Registry is strengthen by academic work that assesses the best practices in the broader context of electronic registries.
This project is undertaken under the joint auspices with the University of Cambridge and UNIDROIT. These institutions carry the project forward from, and further develop the pioneering work by, the Universities of Oxford and Washington. AWG’s secretary general, acting in his academic capacity, directs the project.
The third workshop of the best practices in the field of electronic registry design and operation project was held on 8-9 April 2019 at the headquarters of UNIDROIT in Rome, Italy.
The fourth workshop on best practices in the field of electronic registry design and operation took place in Rome at the headquarters of UNIDROIT on 9 September 2020.
More information on the project may be found here.
Technical note: We use the phrase ‘cape town convention’ to mean the convention on international interests in mobile equipment and its aircraft protocol. Where needed, the ‘convention’ and ‘protocol’ are referred to individually.
