Advantages of International Aircraft Leasing

Aircraft leasing is one of the most efficient financial models, allowing airlines, private operators, and business aviation to use modern airplanes and helicopters without the need for significant initial investments. This tool is widely used across the globe and is regulated by a combination of international and national laws, including aviation law and international financial regulations.

Diverse Forms of Aircraft Leasing

Several forms of aircraft leasing are commonly used in global practice, each offering distinct advantages:

  • Operating Lease – Temporary leasing of an aircraft without an obligation to purchase it afterward.
  • Financial Lease – Long-term lease with the option to acquire the aircraft at the end of the contract.
  • ACMI Lease (Aircraft, Crew, Maintenance, and Insurance) – A lease that includes a full-service package, covering crew, technical maintenance, and insurance.

Selecting the optimal leasing structure requires legal and financial expertise, along with precise transaction terms assessment.

Flexibility and Convenient Lease Calculation

With advancements in financial technology, it is now possible to calculate leasing costs online using specialized calculators. These tools consider various factors such as lease duration, aircraft type, interest rates, and operational conditions. Modern digital solutions enable the modeling of contract terms and forecasting of financial commitments.

Legal Framework for Aircraft Leasing

International aviation law plays a crucial role in aircraft leasing transactions, governing registration, maintenance, insurance, and taxation. Key international agreements affecting aircraft leasing include:

  • Cape Town Convention – Regulates creditor and lessee rights in aircraft leasing transactions.
  • Montreal Convention – Defines airline liability in international air transport.
  • Chicago Convention – Establishes fundamental rules for international civil aviation.

Companies operating in the global aviation market must also consider national legal requirements and regulatory compliance in various jurisdictions.

Transparency and Confidentiality in Leasing Transactions

In most countries, aircraft leasing agreements do not require public disclosure of ultimate beneficiaries, ensuring a high level of confidentiality and protecting the interests of all parties involved.

Financial Efficiency and Tax Benefits

Aircraft leasing helps reduce tax burdens through depreciation mechanisms, optimized tax liabilities, and specialized taxation regimes. Many countries offer favorable tax conditions, including VAT exemptions and tax incentives for airlines and aviation companies.

Freedom of Currency Transactions and Global Settlements

In most jurisdictions, aircraft leasing transactions are not restricted by currency regulations, allowing lessees to utilize global payment systems and engage with international financial institutions. This flexibility enhances financial efficiency and simplifies payment processes.

The Future of Global Aircraft Leasing

The demand for aircraft leasing continues to grow, driven by:

  • The expansion of civil aviation
  • Increased demand for private and corporate air travel
  • The need for airlines to renew their fleets with minimal financial risks

Choosing the right leasing model, ensuring proper legal support, and conducting professional financial analysis allow businesses to fully leverage the benefits of aircraft leasing worldwide.

The Thirteenth Air Law Conference in Dubai

The Al Shindagha Museum, located on the shores of Dubai Creek in the renowned historic district of Al Shindagha, has been chosen as the venue for the 13th Conference on Aviation Law. This museum serves as a beacon of Emirati heritage, bridging the rich past with the future and showcasing contemporary Emirati identity.

The museum complex consists of 21 unique structures, including the House of Sheikh Saeed Al Maktoum, built in 1896. Until the mid-20th century, it was the residence of the ruling Al Maktoum dynasty, to which Dubai’s current emir belongs. Today, the building houses a museum dedicated to the ruling family.

For the conference, a spacious and well-lit Visitor Center has been designated, seamlessly blending with its historical surroundings. Its modern facilities will ensure a comfortable experience for delegates throughout the working day.

As part of the event, delegates will be offered a guided tour within the walls of Al Shindagha Museum, providing an immersive journey through the history of human innovation, resilience, and the drive for progress that has shaped modern Dubai.

This setting allowed participants not only to dive into discussions but also to experience the hospitality and grandeur of the Emirates.

The inspiration for the discussions came from the panel “Existential Threats and Risks for Aviation,” moderated by Professor Shadi Alshdaifat, an expert in international public law from the University of Sharjah. Notable presentations included those by Maxim Astafyev (Deputy General Director for Legal Support at S7 Airlines, Moscow) and Hao Liu (Secretary General of JARUS, Beijing).

Dmitry Zverev, State Secretary and Deputy Minister of Transport of the Russian Federation, presented Russia’s vision for global cooperation. Rajesh Singh (Special Director of InterGlobe Aviation, India) shed light on regional issues in India and their potential solutions.

Another highly anticipated panel was “Financing in Aviation or Money Down the Drain?” moderated by Ilya Kabachnik (Deputy General Director for Aviation Insurance at AlfaStrakhovanie, Moscow). Speakers such as Vladislav Rikoff (Partner and Head of Aviation and Asset Financing Practice, BGP Litigation, Moscow), Sherif Hosseini (Partner and Head of Aviation Practice at Matouk Bassiouny & Hennawy, Cairo), and Vladimir Kilinkarov (Partner and Head of Infrastructure and PPP Practice at Nextons, Moscow) discussed the future of financing, leasing, and public-private partnership (PPP) projects. This session offered a deeper understanding of the financial aspects of aviation, their impact on industry growth, and capital management strategies.

The “The Passenger is Always Right! – A Theorem or an Axiom?” panel, moderated by Mia Wouters, Professor of Aviation Law at Ghent University (Brussels), addressed pressing issues related to passenger rights and airline liability. Speakers included Angela Norina (Partner, Norina and Partners, Vladivostok), Rinat Gareev (Senior Legal Advisor, Whitecliff Management, Dubai), Yuri Morozov (Senior Partner, Attorneys Group, Moscow), and Zlata Vorontsova (Head of Marketing and PR, TCP, Moscow).

The “Manned and Unmanned Aviation: Liability and Obligations” panel, moderated by Hao Liu, also generated extraordinary interest. The session featured presentations by Anton Nikiforov (Aviation Expert, Moscow), Olga Koloshich (Head of Legal and HR Department, Ministry of Transport and Communications of the Republic of Belarus, Minsk), Carlos Beltran (Chief Operating Officer, ATAA, Dubai), and Gleb Babintsev (CEO, AERONEXT Association, Moscow). The discussions were particularly heated, covering both the future of unmanned technologies and issues of liability surrounding their implementation.

After the intensive program, participants enjoyed a gala dinner aboard a three-deck yacht, taking in the stunning night view of Dubai, which glowed with bright lights, symbolizing the unity of the international aviation community. This conference marked an important milestone for the development of the industry, bringing specialists from around the world together in pursuit of a safe and efficient future for aviation.

Once the supplier is selected, a contract must be signed specifying delivery terms, obligations of the parties, deadlines, and cost. At this stage, the involvement of a lawyer is critical to ensure the contract complies with the law and serves the client’s interests.

Situations often arise when a supplier violates contract terms, fails to meet deadlines, or delivers substandard products. A lawyer can assist in such matters, from negotiations and out-of-court dispute resolution to representing the client’s interests in court.

Aviation spare parts supply contracts often contain numerous conditions that must be strictly followed. A lawyer monitors the fulfillment of all contractual obligations and helps resolve conflicts related to the violation of these terms.

In case of disagreements with suppliers, a lawyer can help settle the dispute out of court, preserving business relationships and avoiding unnecessary legal costs.
