THE CAPE TOWN CONVENTION COMPLIANCE DRIVE IN NIGERIA: IMPLICATIONS OF THE IDERA ENFORCEMENT FRAMEWORK FOR AIRCRAFT FINANCING AND LEASING

Abstract

Aircraft financing and leasing are inextricably linked to the ability of lenders and lessors to effectively enforce their rights following an airline default. The substantial value and inherent mobility of aircraft render effective repossession and deregistration mechanisms particularly critical to financiers and lessors. Accordingly, the value of an aircraft may provide only limited security where the applicable legal framework does not afford a clear, reliable, and expeditious means of recovering and deregistering the aircraft following default.

The Convention on International Interests in Mobile Equipment and its Protocol on Matters Specific to Aircraft Equipment (collectively, the “Cape Town Convention”) establish an international framework for protecting creditors and facilitating the financing and leasing of aircraft. Nigeria is a contracting state to the Convention and its Aircraft Protocol, and has undertaken to give effect to their provisions within its legal and aviation framework.

Against this backdrop, Nigeria has reinforced the practical enforcement of its obligations under the Cape Town Convention, notably through the Federal High Court (Cape Town Convention and Aircraft Protocol) Practice Directions 2024 and the Nigeria Civil Aviation Authority’s (NCAA) procedures for the recording and enforcement of Irrevocable Deregistration and Export Request Authorisations (IDERA).

This article examines Nigeria’s Cape Town Convention compliance framework, with particular emphasis on the enforcement of IDERA. It considers the implications of recent reforms for aircraft financing and leasing, including their impact on creditor protection, access to international capital, lease pricing, repossession risk, and the overall attractiveness of Nigeria’s aviation market. It further identifies the practical and legal challenges that must be addressed to ensure that the evolving compliance framework translates into consistent, predictable, and effective enforcement outcomes.

Introduction

Aircraft acquisition is capital-intensive, and airlines frequently rely on leasing and external financing to expand and maintain their fleets. The ability of financiers and lessors to recover an aircraft following default is therefore a critical consideration in determining whether financing will be made available and, where available, on what terms.

The Cape Town Convention was developed to establish a relatively predictable international legal framework for transactions involving high-value mobile assets, including aircraft and aircraft engines. Its Aircraft Protocol supplements this framework with rules specific to aircraft objects and provides remedies intended to facilitate the effective enforcement of creditors’ rights.

The treaty establishes international standards governing the registration of contracts of sale, including through designated registration agencies, as well as security interests (liens), leases, and conditional sales contracts. It also provides for various legal remedies in cases of default under financing agreements, including repossession, while addressing the implications of the bankruptcy laws of individual States.

Nigeria is a Contracting State to the Cape Town Convention and the Aircraft Protocol, which have been domesticated into Nigerian law by Section 50(2) of the Civil Aviation Act 2022. By virtue of this provision, the Convention and the Aircraft Protocol have the force of law in Nigeria, subject to the provisions of the Constitution of the Federal Republic of Nigeria 1999 (as amended).

Notwithstanding this legal framework, concerns regarding the practical enforcement of creditors’ rights have historically affected Nigeria’s attractiveness to international aircraft financiers and lessors. Delays in repossession, uncertainty surrounding deregistration and export, and the prospect of protracted litigation have contributed to concerns regarding enforcement risk.

Recent regulatory and judicial developments represent efforts to address these concerns. In September 2024, the Federal High Court issued the Federal High Court (Cape Town Convention and Aircraft Protocol) Practice Directions 2024, while, in October 2024, the Nigeria Civil Aviation Authority (NCAA) issued an Advisory Circular setting out procedures for the recordation and enforcement of Irrevocable Deregistration and Export Request Authorisations (IDERA). These measures form part of a broader compliance drive aimed at strengthening the certainty and effectiveness of Nigeria’s aircraft financing and leasing regime.

The Cape Town Convention Framework in Nigeria

The Cape Town Convention establishes an international system for recognising and protecting interests in aircraft and other qualifying mobile equipment. It enables creditors to register international interests in the International Registry and provides remedies that may be exercised following a debtor’s default.

The Aircraft Protocol supplements the Convention by establishing rules specifically applicable to aircraft objects. Among its key provisions is the IDERA regime, which enables the use of an Irrevocable Deregistration and Export Request Authorisation.

An IDERA is an instrument issued by an aircraft operator or owner in favour of an authorised party, typically a creditor or lessor. It authorises the designated party to procure the deregistration of the aircraft and its export from the state of registration. Once properly recorded, an IDERA is intended to provide a relatively direct mechanism for exercising these remedies following default, subject to applicable aviation safety laws and regulations.

The significance of an IDERA lies in its potential to mitigate the uncertainty that may otherwise arise from domestic administrative processes when a creditor seeks to exercise its contractual and Convention-based remedies. For aircraft financiers, therefore, an IDERA is more than a documentary instrument; it provides an additional layer of protection by establishing a recognised pathway for the deregistration and export of an aircraft once the relevant contractual and Convention requirements have been satisfied.

Nigeria's IDERA Enforcement Framework

The effectiveness of an IDERA depends significantly on the willingness and capacity of the national aircraft registry to recognise and give effect to it.

In Nigeria, the Nigeria Civil Aviation Authority (NCAA) issued an Advisory Circular on October 16, 2024, setting out procedures for the recordation of IDERA and the deregistration of aircraft pursuant to a recorded IDERA. The framework is intended to ensure the proper recordation of IDERA instruments and to establish a clear administrative process for applications relating to deregistration and export.

The framework places particular emphasis on the timely recordation of IDERAs and seeks to streamline the administrative process for deregistration. Under the current guidance, where an IDERA has been duly recorded, an authorised party, typically a lessor or creditor, may seek the deregistration and export of the aircraft without first obtaining a court order, subject to compliance with the applicable documentary, procedural, and aviation safety requirements.

This is significant because the effectiveness of the Cape Town Convention rests not merely on the recognition of creditors’ rights, but also on the ability to exercise those rights expeditiously and with a reasonable degree of certainty following default.

An IDERA that cannot be efficiently recorded or given effect to offers limited practical protection to a financier or lessor. Conversely, an administrative framework that enables an authorised party to pursue deregistration and export through a clear and predictable process following default can materially reduce the enforcement risk associated with aircraft financing and leasing transactions.

The Federal High Court Practice Directions 2024

The introduction of the Federal High Court (Cape Town Convention and Aircraft Protocol) Practice Directions 2024, represents a further significant component of Nigeria’s efforts to strengthen its compliance with the Cape Town Convention.

Issued in September 2024, the Practice Directions seeks to promote greater consistency and predictability in the judicial treatment of transactions and disputes falling within the scope of the Cape Town Convention and the Aircraft Protocol. In particular, it provides a procedural framework for the enforcement of contracts of sale, security interests, leases, and conditional sale agreements involving aircraft and other relevant assets.

The significance of the Practice Directions is more apparent when considered against the history of aircraft repossession disputes in Nigeria. Where a lessor or financier seeks to exercise contractual or Convention-based remedies, protracted litigation or interim orders that delay repossession may substantially diminish the commercial value of those remedies. The ability to obtain timely and predictable judicial relief is therefore central to the effectiveness of the broader Cape Town Convention framework.

The Practice Directions accordingly seek to enhance judicial predictability by providing the Federal High Court with a defined procedural framework for matters arising under the Cape Town Convention and the Aircraft Protocol. By promoting greater uniformity in the treatment of such proceedings, they have the potential to reduce uncertainty for international financiers and lessors assessing enforcement risk in Nigeria.

The practical importance of the Practice Directions has been demonstrated in proceedings involving Export Development Canada (EDC) and Arik Air. On November 27, 2024, the Federal High Court in Lagos, presided over by Justice Alexander Oluseyi Owoeye, granted EDC, a Canadian financier, the right to repossess and dismantle a CRJ1000 aircraft leased to Arik Air. The aircraft had been grounded since 2019 and deregistered in 2022 following Arik Air’s default. This decision is significant because it demonstrates the practical use of the Cape Town Convention framework in addressing the recovery of aircraft subject to competing claims and enforcement obstacles in Nigeria.

Nevertheless, the existence of Practice Directions does not, in itself, eliminate the broader enforcement risks that may arise in aircraft financing transactions. Questions concerning their interaction with existing legislation, insolvency law, appellate proceedings, and other applicable Nigerian laws may still arise. The ultimate effectiveness of the framework will therefore depend not merely on the existence of the Practice Directions, but on the consistency with which Nigerian courts interpret and apply the Convention and its associated remedies in practice.

Implications for Aircraft Financing

The strengthening of Nigeria’s Cape Town Convention compliance framework carries significant implications for the availability and terms of aircraft financing.

First, it has the potential to mitigate creditor risk. Financiers are more likely to commit capital where the legal consequences of an airline default can be reasonably anticipated. An effective IDERA regime can reduce uncertainty surrounding the recovery, deregistration, and export of a financed aircraft, thereby providing greater assurance regarding the enforceability of the financier’s rights.

This, in turn, may influence the willingness of international banks, lessors, export credit agencies, and other financial institutions to extend financing to Nigerian airlines.

Second, improved enforcement certainty may contribute to a reduction in the cost of aircraft financing. Where enforcement risk is perceived to be elevated, financiers may seek to compensate through higher interest rates, additional security requirements, shorter financing tenors, or more restrictive contractual terms. A more robust legal and enforcement environment may therefore reduce the risk premium attached to aircraft financing transactions involving Nigerian operators.

Third, stronger compliance may enhance Nigerian airlines’ access to international financing structures. Cross-border aircraft finance transactions are frequently structured on the expectation that the Cape Town Convention will provide a predictable framework for protecting and enforcing the financier’s interests. Greater certainty in the application of that framework may consequently make Nigerian operators more attractive counterparties to foreign lessors and financiers. It has also improved financier confidence in the Nigerian aviation market. Since the ability to recover an aircraft is an important factor in determining financing risk, greater certainty around enforcement could encourage international lenders and lessors to provide financing to Nigerian airlines on more favourable terms.

Nigeria’s reported Cape Town Convention compliance score increased from 70.5% to 75.5% in 2026, following the operationalization of the IDERA procedure and the Practice Directions. While a compliance score does not, in itself, guarantee access to financing or more favourable financing terms, sustained improvement in Nigeria’s compliance record may contribute to greater confidence among international capital providers and, over time, strengthen Nigeria’s position within the international aircraft finance market.

Impact on Transaction Structuring and Legal Due Diligence

The strengthening of Nigeria’s Cape Town Convention compliance framework has significant implications for the structuring and due diligence of aircraft financing and leasing transactions. Financiers and lessors must ensure that IDERA documentation is properly prepared, executed, and recorded in accordance with the NCAA’s 2024 Advisory Circular, NCAA-AC-AWS001A. Under clause 3.2, an IDERA is required to be submitted in writing, substantially in the form prescribed by the Aircraft Protocol, and must identify the relevant aircraft and be duly executed by the applicant. The Circular further provides under clause 3.2 that only one IDERA may be recorded in respect of an aircraft at any given time, such that a further IDERA cannot be recorded while an earlier IDERA remains valid and unrevoked.

The identity and authority of the person seeking to exercise the IDERA are equally important. Under clause 3.3, an authorised party may act through a certified designee or duly appointed agent, provided the requisite notarised power of attorney is submitted. Clause 3.4 further provides that an IDERA may only be revoked by the authorised party in writing, and not by the applicant. These requirements are material to transaction structuring because they affect the validity, control, and subsequent enforceability of the IDERA following default.

The transaction should also be structured to ensure that the relevant international interests are duly registered on the International Registry and that the creditor’s security interests are appropriately perfected under both the Cape Town Convention framework and applicable Nigerian law. Legal due diligence would therefore require consideration of matters extending beyond the principal lease or financing agreement, including the aircraft’s registration and ownership status, existing registered interests on the Nigerian Civil Aircraft Register of Liens and the International Registry, NCAA records, IDERA documentation, mortgage interests, insurance arrangements, and applicable regulatory approvals. Particular attention should be given to the priority of existing interests and any matters capable of affecting the creditor’s ability to exercise its rights following default.

The importance of these matters is reinforced by the requirements governing the exercise of IDERA remedies. Under clause 3.6 of the Advisory Circular, an authorised party seeking to exercise its rights must submit a written request identifying the applicable rights or remedies under clause 3.6(a), together with the recorded IDERA under clause 3.6(b). Clause 3.6(c) further requires the authorised party to certify that there are no registered interests ranking in priority to its interest or, where such interests exist, that they have been discharged or that their holders have consented to the proposed exercise of remedies. The request must also satisfy the execution requirements under clause 3.6(d) and be accompanied by the prescribed Form AC-AWS001G and applicable statutory fees pursuant to clause 3.6(e).

Where these requirements have been satisfied, clause 3.6(i) provides for the NCAA to effect deregistration within five working days of receipt of the request. The NCAA is thereafter required under clause 3.6(ii) to issue the certificate of deregistration and notify the next State of Registry. Clause 3.6(iii) further contemplates the facilitation of the aircraft’s export and physical transfer, subject to applicable requirements concerning ferry or special flight permits. Significantly, the final provision of the relevant procedure states that no additional consent, approval, court order, or action by the applicant or lessee is required for the NCAA to act on a properly submitted request.

These provisions materially affect the manner in which aircraft financing transactions should be structured and reviewed from the outset. The effectiveness of an IDERA is not determined merely by its execution; its practical utility depends on its valid recordation and compliance with the requirements governing the subsequent exercise of the relevant remedies. A deficiency in the recordation process, an undisclosed prior interest, or a failure to satisfy the prescribed requirements under clause 3.6 may therefore undermine the creditor’s ability to obtain the administrative relief contemplated by the Circular.

Challenges to Effective IDERA Enforcement

Notwithstanding the reforms introduced to strengthen Nigeria’s Cape Town Convention framework, challenges remain as to whether the enhanced legal and regulatory framework will translate into effective enforcement in practice.

A principal challenge lies in bridging the gap between formal legal compliance and practical enforceability. The existence of legislation, regulatory procedures, advisory circulars, and Practice Directions does not, in itself, guarantee the expeditious exercise of a creditor’s rights. The real test of the framework will arise when a creditor seeks to enforce its rights following an actual default, particularly where the debtor resists repossession or competing creditors assert claims over the aircraft. How the NCAA and the courts respond in such circumstances will therefore be important in determining whether the reforms provide the degree of certainty contemplated by the Cape Town Convention.

Judicial consistency presents a related concern. Aircraft finance disputes may involve complex questions concerning contractual rights, security interests, insolvency, jurisdiction, and the interaction between domestic law and Nigeria’s international obligations. Although the Practice Directions seek to promote greater consistency in the treatment of matters arising under the Cape Town Convention and the Aircraft Protocol, divergent approaches to their interpretation or application could undermine the predictability that the framework is intended to provide. For financiers and lessors, the availability of timely and consistent judicial relief remains important to the commercial value of their enforcement rights.

The enforcement landscape becomes more complex where an airline is subject to insolvency proceedings. An insolvent airline may have multiple secured and unsecured creditors, competing claims over its assets, and other interests capable of affecting the exercise of enforcement rights. The practical effectiveness of a creditor’s rights under the Cape Town Convention may therefore depend, in part, on how those rights interact with applicable Nigerian insolvency law and the claims of other creditors. The relationship between international aircraft finance protections and domestic insolvency principles consequently remains an important consideration in assessing the strength of the enforcement framework.

Effective implementation also depends on adequate institutional and technical capacity. The NCAA, the courts, legal practitioners, airlines, financiers, and other stakeholders must have a sufficient understanding of the Convention, the Aircraft Protocol, and the procedures governing the recordation and exercise of IDERA rights. Where these requirements are misunderstood, inconsistently applied, or affected by administrative delays, the practical effectiveness of the framework may be diminished notwithstanding the existence of an otherwise robust legal regime.

These concerns are particularly significant because Nigeria’s historical compliance challenges have extended beyond the legislative incorporation of the Cape Town Convention. Concerns relating to judicial delays, enforcement uncertainty, and institutional capacity have also influenced perceptions of Nigeria’s aircraft financing environment. The recent reforms therefore provide an important foundation for improving enforcement certainty, but their long-term significance will ultimately depend on how consistently and effectively they are applied in practice.

Implications for Nigerian Airlines

The strengthening of creditor protections under Nigeria’s Cape Town Convention framework also carries significant implications for Nigerian airlines. Greater certainty for financiers and lessors necessarily means greater certainty regarding the consequences of default for operators.

Airlines entering into aircraft financing or leasing arrangements must therefore recognise that default provisions may carry more immediate practical consequences where the relevant Cape Town Convention mechanisms, including a duly recorded IDERA, have been properly implemented. The availability of more direct mechanisms for exercising creditor rights may reduce the scope for prolonged resistance to repossession, deregistration, or export following a qualifying default.

This makes compliance with contractual obligations particularly important. Lease payments, maintenance requirements, insurance obligations, registration and operational requirements, and the preservation of the aircraft’s condition may all assume greater significance where a creditor has a clear and enforceable mechanism for responding to default. Airlines must therefore treat these obligations not merely as contractual requirements, but as matters capable of directly affecting their continued possession and operation of the aircraft.

Internal compliance and financial monitoring systems will also become increasingly important. Early identification of payment defaults, covenant breaches, maintenance deficiencies, or other events capable of triggering enforcement rights may give an airline an opportunity to engage with its financier or lessor before formal enforcement mechanisms are activated. Timely engagement may, where appropriate, facilitate restructuring or other consensual arrangements and help mitigate the disruption associated with repossession.

The objective for Nigerian airlines should therefore extend beyond simply avoiding repossession. A stronger compliance culture and a more disciplined approach to aircraft financing obligations can enhance an airline’s credibility with international lessors and financiers, preserve access to aircraft and external capital, and ultimately support the sustainability of its fleet and operations.

The Broader Significance for Nigeria's Aviation Sector

Nigeria’s efforts to strengthen its compliance with the Cape Town Convention have implications beyond individual aircraft financing and leasing transactions. The availability of reliable aircraft financing is closely linked to the ability of Nigerian airlines to acquire modern aircraft, expand and renew their fleets, improve operational efficiency, and remain competitive within regional and international markets. Where financiers and lessors have greater confidence in the enforceability of their rights, Nigerian operators may be better positioned to access the capital required for fleet development.

A credible enforcement framework can therefore contribute to the broader development of Nigeria’s aviation sector by making the market more attractive to international lessors, financiers, and other capital providers. Improved compliance may also encourage the development of domestic aviation finance structures and create greater opportunities for Nigerian financial institutions to participate in aircraft financing transactions.

The long-term benefits, however, will depend on whether the recent reforms produce consistent and demonstrable enforcement outcomes. International financiers are ultimately concerned not only with the rights available under Nigerian law, but with whether those rights can be exercised efficiently and with reasonable certainty when a transaction encounters difficulties. The practical application of the reforms will therefore be as important as the reforms themselves.

Practical Compliance Measures for Airlines, Lessors and Financiers

Stakeholders involved in aircraft financing and leasing should adopt a proactive approach to compliance with the Cape Town Convention framework.

Airlines should ensure that relevant lease and financing documents are properly executed and that IDERA requirements are addressed at the appropriate stage of the transaction. They should also maintain accurate records relating to aircraft ownership, registration, financing arrangements, insurance, and regulatory filings. Proper internal record-keeping is particularly important where these documents may later be required to establish the parties’ respective rights or respond to an enforcement action.

Lessors and financiers should undertake comprehensive legal due diligence before entering into transactions involving Nigerian operators. This should include verification of the aircraft’s registration and ownership status, existing registered interests, IDERA recordation, International Registry registrations, and other relevant security interests. The priority and validity of existing interests should also be examined to identify any matter that could affect the creditor’s position following default.

Transaction documents should further set out the parties’ rights and obligations with sufficient clarity, particularly in relation to events of default and the remedies available thereafter. The enforcement structure should be consistent with the Cape Town Convention, the Aircraft Protocol, the applicable NCAA procedures, and relevant Nigerian law, so that the contractual arrangements do not create avoidable difficulties when enforcement becomes necessary.

Legal due diligence and transaction structuring also have an important role to play in anticipating potential insolvency, regulatory, and enforcement issues from the outset. The objective should not merely be to ensure that the transaction is compliant at closing, but to preserve the parties’ respective rights throughout the life of the transaction and, where necessary, facilitate their effective exercise following default.

Finally, stakeholders should continue to monitor developments in Nigerian aviation legislation, NCAA procedures, Federal High Court Practice Directions, and relevant international developments under the Cape Town Convention framework. Compliance should therefore be regarded as an ongoing obligation rather than a requirement that ends once the transaction has been completed.

Conclusion

Nigeria’s renewed focus on compliance with the Cape Town Convention represents a significant development in the country’s aircraft financing and leasing landscape. The introduction of the Federal High Court (Cape Town Convention and Aircraft Protocol) Practice Directions 2024, together with the strengthening of the NCAA’s procedures for the recordation and enforcement of IDERA, reflects a broader effort to provide greater certainty and protection to aircraft financiers and lessors operating within the Nigerian market.

The effectiveness of these reforms, however, will ultimately be determined by their application in practice. A predictable and effective IDERA enforcement mechanism can mitigate creditor risk, strengthen confidence in Nigerian aviation transactions, facilitate access to international capital, and potentially contribute to more favourable financing and leasing terms. These benefits will depend not merely on the existence of the relevant legal framework, but on the extent to which creditors can rely on it when enforcement becomes necessary.

For Nigerian airlines, the reforms equally carry important consequences. As the enforcement of creditor rights becomes more predictable, defaults may attract more immediate and commercially significant consequences. Airlines must therefore place greater emphasis on compliance with their contractual, financial, operational, and regulatory obligations throughout the life of their financing and leasing arrangements.

Nigeria’s Cape Town Convention compliance drive should therefore be viewed not simply as a regulatory exercise, but as part of a broader effort to strengthen the country’s aircraft finance ecosystem. If supported by consistent judicial enforcement, effective regulatory administration, adequate institutional capacity, and sustained engagement with international stakeholders, the strengthened IDERA framework can contribute to making Nigeria a more predictable and attractive market for aircraft financing and leasing.
