Banking Law and Finance Lease Structures for Aircraft in Spain

Introduction

Aircraft finance leasing is an important method of financing commercial aviation because aircraft require very large amounts of capital. Instead of purchasing an aircraft entirely with its own funds, an airline may obtain the economic use of the aircraft through a leasing structure financed by a bank, leasing company, special-purpose vehicle or group of financial institutions.

A finance lease generally involves a lessor acquiring an aircraft and making it available to the airline or other operator for an agreed period in return for periodic payments. Economically, the arrangement may transfer most of the risks and benefits associated with the aircraft to the lessee, even though legal ownership remains with the lessor during the lease.

In Spain, aircraft finance leasing is governed by several overlapping areas of law rather than one dedicated aircraft-finance statute. Relevant rules include banking law, commercial and contract law, aviation law, aircraft-registration rules, security law, insolvency law, tax law and EU aviation legislation.

International instruments, particularly the Cape Town Convention and Aircraft Protocol, are also highly significant for modern aircraft financing.

Legal and Regulatory Framework

Where Spanish banks participate in aircraft financing, Law 10/2014 on the organisation, supervision and solvency of credit institutions forms part of the general banking framework.

Spanish credit institutions are also subject to EU prudential requirements and supervision by the Banco de España and, where applicable, the European Central Bank within the Single Supervisory Mechanism.

The traditional Spanish aviation framework includes the Air Navigation Act 48/1960, together with subsequent legislation and EU aviation rules.

Aircraft ownership and interests may also involve the Spanish Aircraft Register and the Registry of Movable Property, depending on the nature of the right being registered.

Spain's participation in the Cape Town system adds an important international dimension for qualifying aircraft objects and international interests.

Basic Finance Lease Structure

A typical aircraft finance lease can involve three principal parties:

1. Supplier or manufacturer – sells the aircraft.

2. Lessor or financing vehicle – purchases and legally owns the aircraft.

3. Airline or lessee – operates the aircraft and pays periodic rentals.

A bank can finance the lessor's acquisition of the aircraft. In more complicated transactions, several banks, security trustees, export-credit agencies, lessors and special-purpose companies may participate.

The lease payments are normally designed to allow the financing structure to recover a substantial proportion of the aircraft's acquisition cost together with the agreed financial return.

Finance Lease Versus Operating Lease

A distinction should be made between a finance lease and an operating lease.

Under a finance lease, the economic structure is predominantly financing-oriented. The lessee may bear substantial risks associated with maintenance, insurance, operation and residual value, depending upon the contract.

An operating lease generally places greater residual-value exposure on the lessor and is frequently structured for a shorter period relative to the aircraft's economic life.

The contractual title given to the transaction is not always decisive.

Courts, regulators and accounting frameworks can examine the economic substance of the arrangement when determining its proper legal or accounting treatment.

Aircraft Ownership

In a finance lease, legal title commonly remains with the lessor.

This ownership structure provides important protection to the financier because the aircraft is not simply an unsecured asset of the airline.

However, ownership alone does not eliminate legal risk.

The lender and lessor must ensure that ownership, lease rights and security interests have been correctly created and registered where registration is required or advisable.

Aircraft are high-value mobile assets that regularly cross national borders. Clear documentation of title is therefore particularly important.

Registration of Aircraft and Security Interests

Registration performs an essential role in aircraft finance.

The parties should determine which rights must be entered in the relevant Spanish registries and whether an international interest should also be registered under the Cape Town Convention system.

Proper registration can help establish priority against competing creditors.

This becomes particularly important if the airline, lessor or financing vehicle enters insolvency proceedings.

A lender that fails to properly perfect or register its security may find that another creditor possesses superior rights.

Cape Town Convention

The Convention on International Interests in Mobile Equipment and its Protocol on Matters Specific to Aircraft Equipment create an international system for protecting interests in aircraft objects.

The Cape Town framework is particularly important because aircraft regularly operate internationally.

It provides mechanisms concerning:

creation and recognition of international interests;

registration;

priority;

default remedies;

insolvency;

and international recognition of relevant interests.

For banks, registration of a qualifying international interest can substantially improve legal certainty.

However, Cape Town protection does not eliminate the need to examine Spanish domestic law. The international framework and national legal rules operate together according to their respective fields of application.

Security Package

A large aircraft financing transaction commonly involves more than ownership of the aircraft.

The financing parties may seek a broader security package.

Depending upon the structure and applicable law, this may involve security over the aircraft, assignment of lease receivables, rights relating to insurance proceeds, bank accounts and other contractual rights.

The purpose is to ensure that if the borrower defaults, the lender has several legally available sources of recovery.

Security documentation should clearly identify the secured obligations and relevant assets.

Assignment of Lease Rentals

Where a bank finances the lessor, lease rentals can become an important source of repayment.

The lessor may therefore assign or secure its rights to receive rental payments in favour of the financing bank.

This creates a connection between the underlying aircraft lease and the loan agreement.

The bank must examine whether the assignment satisfies applicable Spanish requirements and whether notice, registration or other formalities are necessary.

Aircraft Mortgages

Aircraft can also be subject to security arrangements comparable to mortgages over other valuable assets.

Aircraft mortgages can be important where the airline or another borrower owns the aircraft and uses it as security for financing.

A lender should verify:

the identity of the aircraft;

ownership;

existing registered interests;

priority;

formal validity of the mortgage;

and registration requirements.

Aircraft identification normally relies upon specific manufacturer and registration information rather than a generic description.

Insurance

Aircraft finance agreements normally contain extensive insurance requirements.

Commercial aircraft can be exposed to physical damage, liability and other operational risks.

Financing documentation can require the airline to maintain specified insurance coverage and may protect the financial interests of lessors and lenders through appropriate insurance arrangements.

The lender must also consider what happens to insurance proceeds following serious damage or loss.

Depending upon the contract, proceeds may be applied toward repair, replacement or repayment of financing.

Maintenance and Aircraft Value

Aircraft value depends heavily upon maintenance.

Consequently, finance leases usually impose detailed maintenance obligations upon the lessee.

Requirements can concern engines, airframes, components, maintenance records and compliance with aviation-authority requirements.

Maintenance reserves may also be used in certain leasing structures.

From the bank's perspective, inadequate maintenance can substantially reduce collateral value even if legal title remains perfectly protected.

Default

Events of default can include:

failure to pay rent;

breach of financial covenants;

failure to maintain insurance;

unauthorised disposal of the aircraft;

serious regulatory breaches;

cross-default under other financing;

and insolvency.

After default, contractual remedies may include acceleration, termination and enforcement against security.

However, contractual rights must be exercised consistently with mandatory Spanish, EU and applicable international law.

Insolvency of the Airline

Airline insolvency is one of the most important risks in aircraft financing.

The lessor may legally own the aircraft while the insolvent airline physically possesses and operates it.

Spanish insolvency legislation therefore interacts directly with leasing and security rights.

The legal characterization of the arrangement becomes important when determining whether the financier is primarily an owner, secured creditor or ordinary creditor for particular purposes.

Cape Town protections may also become relevant where the aircraft and interests fall within the Convention.

Case Laws

Aircraft finance-leasing litigation in Spain is relatively specialised. The following Spanish and European decisions provide important principles concerning financial leasing, contractual characterization, aviation obligations and aircraft-related financial risk.

1. Spanish Supreme Court – Finance Leasing Jurisprudence

The Tribunal Supremo has repeatedly recognised financial leasing as a financing transaction involving the acquisition of an asset by the leasing entity for use by the customer in return for periodic instalments, normally accompanied by an agreed purchase option.

Spanish jurisprudence focuses upon the economic and contractual characteristics of leasing rather than treating it as an ordinary rental in every circumstance.

Aircraft-finance relevance: An aircraft finance lease should be analysed according to its genuine financing structure and contractual allocation of rights and risks.

2. Spanish Supreme Court – Ownership in Financial Leasing

Spanish Supreme Court jurisprudence has distinguished the legal ownership retained by a leasing company from the economic use enjoyed by the lessee.

The lessee's possession does not automatically make it the legal owner.

Aircraft-finance relevance: Where a lessor retains valid ownership of an aircraft, the airline's operational possession should not automatically be confused with proprietary title.

3. Spanish Supreme Court – Insolvency and Financial Leasing

The Spanish Supreme Court has addressed the treatment of financial-leasing contracts during insolvency proceedings.

Its jurisprudence demonstrates that determining the parties' rights requires examination of the contractual structure, outstanding obligations and applicable insolvency provisions.

Aircraft-finance relevance: Aircraft lessors and banks should structure transactions with insolvency consequences in mind rather than assuming that contractual ownership resolves every enforcement issue.

4. Wallentin-Hermann v Alitalia – C-549/07

The CJEU considered whether technical problems affecting an aircraft could constitute extraordinary circumstances under EU passenger-rights legislation.

It held that ordinary technical problems inherent in airline operations do not automatically qualify as extraordinary circumstances.

Aircraft-finance relevance: Operational and technical risks can create financial exposure for airlines and therefore indirectly affect cash flow, lease-payment capacity and lender risk.

5. Eglītis and Ratnieks v Latvijas Republikas Ekonomikas ministrija – C-294/10

The CJEU examined the extent of an airline's obligations when extraordinary circumstances affect flight operations.

The decision emphasised the measures that air carriers may reasonably be expected to take.

Aircraft-finance relevance: Banks financing aircraft must recognise that airline operating obligations can continue to generate costs during major disruptions.

6. McDonagh v Ryanair Ltd – C-12/11

The CJEU considered airline obligations following disruption caused by the volcanic ash crisis.

It held that extraordinary circumstances do not automatically eliminate the carrier's statutory duty of care toward passengers.

Aircraft-finance relevance: Exceptional events can create prolonged costs for airlines even when the disruption is beyond management's control, affecting financial modelling for aircraft financing.

7. Pešková and Peška v Travel Service – C-315/15

The CJEU considered whether a bird strike could constitute extraordinary circumstances and examined the airline's reasonable-measures obligation.

Aircraft-finance relevance: Physical and operational aviation risks can influence aircraft availability, revenue generation and ultimately the borrower's ability to service lease obligations.

8. Transportes Aéreos Portugueses v flightright – C-74/19

The CJEU further developed the concept of extraordinary circumstances in aviation.

The decision illustrates the continuing importance of operational disruptions and passenger-rights liabilities for airlines.

Aircraft-finance relevance: Aircraft-finance credit analysis must consider regulatory liabilities alongside traditional fuel, maintenance and traffic risks.

Cross-Border Leasing

Aircraft leasing is inherently international.

A Spanish airline might operate an aircraft owned by an Irish lessor, financed by international banks, manufactured in another country and registered under a structure involving several jurisdictions.

The lease therefore needs clear provisions concerning:

governing law;

jurisdiction;

registration;

tax;

insurance;

repossession;

maintenance;

export and deregistration;

and enforcement.

Banks must analyse whether Spanish judgments and security interests will be recognised where the aircraft is physically located.

The Cape Town Convention is particularly useful because it seeks to reduce some of this cross-border uncertainty.

Sale and Leaseback

Another common structure is sale and leaseback.

An airline that already owns an aircraft sells it to a lessor and immediately leases it back.

The airline obtains liquidity while continuing to operate the aircraft.

For the financier, the transaction requires careful examination of whether title was validly transferred and whether the transaction could later be challenged.

The bank should also examine the airline's motivation. A sale-and-leaseback can be a sensible liquidity-management technique, but extensive reliance upon such transactions can sometimes indicate financial pressure.

Special-Purpose Vehicles

Aircraft financing commonly uses special-purpose vehicles (SPVs).

An SPV can acquire the aircraft, borrow the purchase price and lease the aircraft to the airline.

This structure can help separate aircraft ownership from other commercial risks.

However, the bank must ensure that the SPV is genuinely established, has appropriate corporate authority and complies with applicable accounting, tax, beneficial-ownership and regulatory requirements.

The existence of an SPV does not automatically make the transaction bankruptcy-proof.

Tax Considerations

Tax treatment can significantly influence aircraft-leasing structures.

Relevant questions can include corporate taxation, VAT treatment, withholding taxes, depreciation and international tax treaties.

Spain has historically used specialised tax structures in certain asset-financing transactions, including arrangements associated with the former Spanish Tax Lease system.

Aircraft transactions should therefore be structured according to current tax legislation rather than assuming that historical tax advantages remain available.

Tax planning must also respect EU State-aid requirements.

Prudential Treatment for Banks

Banks financing aircraft must calculate credit risk under applicable EU prudential rules.

Aircraft values can fluctuate considerably according to aircraft type, age, engine configuration, maintenance status, market demand and technological developments.

Lenders therefore commonly apply conservative loan-to-value assumptions.

Stress testing can examine scenarios such as:

airline insolvency;

reduced passenger demand;

higher interest rates;

major maintenance requirements;

aircraft grounding;

and falling secondary-market values.

The fact that an aircraft is expensive does not necessarily make it excellent collateral.

Environmental Transition Risk

Environmental regulation represents a growing issue for aircraft financing.

European climate policies, emissions regulation and technological changes may influence the economics of older aircraft.

More fuel-efficient aircraft can command stronger market demand, while inefficient models may experience declining residual values.

Banks should therefore consider whether the financed aircraft could suffer accelerated economic obsolescence.

This creates a connection between traditional aircraft finance and modern climate-risk management.

Repossession and Enforcement

If an airline defaults, the lessor may seek possession of the aircraft while lenders enforce their security rights.

In practice, repossession requires more than simply proving ownership.

The financier may need to deal with airport authorities, maintenance records, registration, insurance, engines, physical location and regulatory requirements.

An aircraft without complete technical records can lose significant market value.

Effective enforcement planning should therefore begin when the financing transaction is created rather than only after default occurs.

Conclusion

Banking Law and Finance Lease Structures for Aircraft in Spain combines banking regulation, leasing law, aviation law, security interests, registration, insolvency rules, taxation and international law.

A typical structure involves a lessor acquiring an aircraft and providing it to an airline in return for periodic lease payments, while banks may finance the acquisition and obtain security over the aircraft, lease receivables and related rights.

Spanish Supreme Court jurisprudence concerning financial leasing, ownership and insolvency, together with aviation decisions such as Wallentin-Hermann, Eglītis and Ratnieks, McDonagh, Pešková and Peška, and Transportes Aéreos Portugueses, illustrates important principles affecting the legal and financial risks surrounding aircraft operations and financing.

The Cape Town Convention and Aircraft Protocol are particularly significant because modern aircraft routinely cross borders and require internationally recognisable security arrangements.

The central principle is that successful aircraft finance depends upon much more than the value of the aircraft itself. Banks and lessors must establish clear ownership, properly perfected security, reliable registration, adequate insurance, maintenance standards, sustainable airline cash flow, insolvency protection and workable cross-border enforcement rights.
