4.125% Senior Notes due 2024

We are offering $500 million aggregate principal amount of 4.125% Senior Notes due 2024 (the "notes"). The notes will bear interest at a
rate of 4.125% per annum. The notes will mature on May 1, 2024. Interest will accrue on the notes from March 20, 2017. Interest on the notes is
payable on May 1 and November 1 of each year, commencing on November 1, 2017.

We may redeem some or all of the notes at any time prior to February 1, 2024 (three months prior to maturity) by paying a specified "make-
whole" premium, plus accrued and unpaid interest, if any, to the redemption date, as described in this prospectus supplement. On and after
February 1, 2024 (three months prior to maturity), we may redeem some or all of the notes at a redemption price of 100% of the principal amount
of the notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date. In addition, prior to May 1, 2020, we may redeem up
to 40% of the aggregate principal amount of the notes with the net proceeds of certain equity offerings at the redemption price set forth in this
prospectus supplement, plus accrued and unpaid interest, if any, to the redemption date. See "Description of the Notes--Optional Redemption. If

SUMMARY

This summary highlights the information contained elsewhere in or incorporated by reference in this prospectus supplement and the
accompanying prospectus. Because this is only a summary, it does not contain all of the information that may be important to you. For a more
complete understanding of this offering, we encourage you to read this entire prospectus supplement and the accompanying prospectus and
the information incorporated by reference herein and therein, including the financial statements and the notes to those statements.

In this prospectus supplement, except as otherwise indicated or the context otherwise requires, the terms "Aircastle," "we," "our" and
"us" refer to Aircastle Limited and its consolidated subsidiaries.

Our Company

We acquire, lease, and sell commercial jet aircraft to airlines throughout the world. As of December 31, 2016, we owned and managed
on behalf of our joint ventures 206 aircraft leased to 71 lessees located in 36 countries. Our aircraft are managed by an experienced team based
in the United States, Ireland and Singapore. Our aircraft are subject to net leases whereby the lessee is generally responsible for maintaining
the aircraft and paying operational, maintenance and insurance costs, although in certain cases, we are obligated to pay a portion of specified
maintenance or modification costs. As of December 31, 2016, the net book value of our flight equipment (including flight equipment held for
lease and net investment in finance and sales-type leases, or "net book value") was $6.51 billion compared to $6.07 billion as of December 31,
2015. Our revenues, net income and Adjusted EBITDA for the year ended December 31, 2016 were $773.0 million, $151.5 million and $768.0
million, respectively, and for the fourth quarter of 2016 were $204.7 million, $67.7 million and $220.5 million, respectively.

Our Industry

Growth in commercial air traffic is broadly correlated with world economic activity and in recent years, has been expanding at a rate of
one and a half to two times that of global GDP growth. The expansion of air travel has driven a rise in the world aircraft fleet. There are
currently approximately 20,000 commercial mainline passenger and freighter aircraft in operation worldwide. This fleet is expected to
continue expanding at an average annual rate of three to four percent over the next 20 years. In addition, aircraft leasing companies own a
significant share of the world's commercial jet aircraft and account for approximately 41% of this fleet.

Notwithstanding the sector's long-term growth, the aviation markets have been, and are expected to remain, subject to economic
variability, as well as to changes in macroeconomic variables such as fuel price levels and foreign exchange rates. The aviation industry is
susceptible to external shocks, such as regional conflicts and terrorist events. Mitigating these risks is the portability of the assets, allowing
aircraft to be redeployed to locations where demand is higher.

Air traffic data for the past several years has shown strong passenger market growth. According to the International Air Transport
Association, during 2016, global passenger traffic increased 6.3% compared to 2015. This strong growth was, in part, stimulated by lower air
fare prices resulting from the significant drop in fuel prices. Air cargo demand, which is more sensitive to economic conditions, appears to
have stabilized. During 2016, air cargo traffic increased 3.8% compared to 2015, but capacity increased 5.3%, further depressing load factors.
This market continues to be hampered by oversupply arising from the rapid growth in belly cargo capacity in passenger aircraft, as well as the
production of dedicated freighter aircraft.

Demand for air travel varies considerably by region. Emerging market economies have generally been experiencing significant increases
in air traffic, driven by rising levels of per capita income. Air traffic growth in

S-1
Table of Contents
some regions is being driven by the proliferation of low cost carriers, which have stimulated demand through lower prices. Mature markets,
such as North America and Western Europe, are likely to grow more slowly in tandem with their economies. Persian Gulf-based Emirates,
Qatar Airways and Etihad Airways are also showing signs of reaching maturity, with their growth rates starting to slow. Airlines operating in
areas with political instability or weakening economies, such as those in Russia, Brazil, and now Turkey, are under pressure, and their near-
term outlook is more uncertain. On balance, we believe air travel will increase over time, and as a result, we expect demand for modern
aircraft will continue to remain strong over the long-term.

Record low fuel prices and interest rates have had a substantial effect on our industry. Between 2012 and 2016, the price of oil dropped
https://www.sec.gov/Archives/edgar/data/1362988/000119312517074914/d350132d424b2.htm[3/9/2017 3:53:09 PM]

424B2
by $67 per barrel, allowing airlines to reduce ticket prices and stimulate aircraft traffic while retaining enough of this benefit to achieve record
profit levels. We believe the prospect of fuel prices having shifted to a lower baseline has shifted lease pricing among different types of
aircraft, generally to the detriment of newer, more fuel efficient aircraft with higher capital costs. The ongoing low interest rate environment
and strong overall performance of the aircraft financing sector has attracted significant new capital, increasing competition for new
investments. The downward trend in fuel prices and interest rates may, however, have ended as fuel prices started rising in 2016, and in early
2017 the price of fuel increased $19 per barrel since January 2016. Likewise, interest rates have started to rise in the United States, with
Federal Reserve guidance suggesting multiple rate hikes are likely subsequent to the December 2016 increase in the Federal Funds rate.

Capital availability for aircraft has varied over time, and we consider this variability to be a basic characteristic of our business. If
pursued properly, this represents an important source of opportunity. Both debt and equity markets have improved globally over the past
several years with the recovery from the global financial crisis. Strong U.S. debt capital market conditions benefited borrowers by permitting
access to financing at historic lows while higher fees have driven down export credit agency ("ECA") demand. Recently, ECA availability has
been curtailed, both in the United States and in Europe, due to political issues and an investigation into possible irregularities, respectively.
Commercial bank debt continues to play a critical role for aircraft finance, although we believe regulatory pressures may ultimately limit its
role.

While financial markets conditions are currently attractive, heightened volatility stemming from global growth concerns and various
geopolitical issues may increase capital costs and limit availability going forward. We believe these market forces should generate attractive
new investment and trading opportunities upon which we are well placed to capitalize given our access to different financing sources, our
limited capital commitments and our reputation as a reliable trading partner. Over the longer term, our strategy is to achieve an investment
grade credit rating, which we believe will reduce our borrowing costs and provide us with more reliable access to debt capital throughout the
business cycle.

Our Business

We originate acquisitions and sales through well-established relationships with airlines, other aircraft lessors, financial institutions and
brokers, as well as other sources. We believe that sourcing such transactions globally through multiple channels provides for a broad and
relatively consistent set of opportunities.

Our objective is to develop and maintain a diverse and stable operating lease portfolio. We review our operating lease portfolio to sell
aircraft opportunistically, to manage our portfolio diversification and to exit from aircraft investments when we believe selling will achieve
better expected risk-adjusted cash flows than reinvesting in and re-leasing the aircraft.

We have an experienced acquisitions and sales team based in Stamford, Connecticut; Dublin, Ireland; and Singapore that maintains
strong relationships with a wide variety of market participants throughout the world. We believe that our seasoned personnel and extensive
industry contacts facilitate our access to acquisition and sales opportunities and that our strong operating track record facilitates our access to
debt and equity capital markets.

S-2
Table of Contents
Potential investments and sales are evaluated by teams comprised of marketing, technical, risk management, financial and legal
professionals. These teams consider a variety of aspects before we commit to purchase or sell an aircraft, including price,
specification/configuration, age, condition and maintenance history, operating efficiency, lease terms, financial condition and liquidity of the
lessee, jurisdiction, industry trends and future redeployment potential and values, among other factors. We believe that utilizing a cross-
functional team of experts to consider investment parameters helps us assess more completely the overall risk and return profile of potential
acquisitions and helps us move forward expeditiously on letters of intent and acquisition documentation.

Nearly all of our aircraft are contracted on operating leases. Under an operating lease, we retain the benefit, and bear the risk, of re-
leasing and of the residual value of the aircraft at the end of the lease. Operating leasing can be an attractive alternative to ownership for an
airline because leasing increases their fleet flexibility, requires lower capital commitments, and significantly reduces aircraft residual value
risks. Under these leases, the lessee agrees to lease an aircraft for a fixed term, although certain of our operating leases allow the lessee the
option to extend the lease for an additional term or, in rare cases, terminate the lease prior to its expiration. As a percentage of lease rental
revenue for the year ended December 31, 2016, our four largest customers, Lion Air, LATAM Airlines Group, Avianca Brazil and South
African Airways, accounted for 7%, 6%, 6% and 5%, respectively.

Each of our leases requires the lessee to pay periodic rentals during the lease term. As of December 31, 2016, rentals on more than 93%
of our leases then in effect, as a percentage of net book value, are fixed and do not vary according to changes in interest rates. For the
remaining leases, rentals are payable on a floating interest-rate basis. Most lease rentals are payable monthly in advance, and all lease rentals
https://www.sec.gov/Archives/edgar/data/1362988/000119312517074914/d350132d424b2.htm[3/9/2017 3:53:09 PM]

424B2
are payable in U.S. dollars.

Our aircraft re-leasing strategy is to develop opportunities proactively, well in advance of scheduled lease expiration, to enable
consideration of a broad set of alternatives, including deployment, sale or part-out, and to allow for reconfiguration or maintenance lead times
where needed. We also take a proactive approach to monitoring the credit quality of our customers, and may seek early return and
redeployment of aircraft if we feel that a lessee is unlikely to perform its obligations under a lease. We have invested significant resources in
developing and implementing what we consider to be state-of-the-art lease management information systems and processes to enable efficient
management of aircraft in our portfolio.

We believe our business approach is differentiated from those of other large leasing companies. Our investment strategy is to seek out
the best risk-adjusted return opportunities across the commercial jet market, so our acquisition targets and growth rates will vary with market
conditions. We prefer to have capital resources available to capture investment opportunities that arise in the context of changing market
circumstances. As such, we limit large, long-term capital commitments and are therefore much less reliant on orders for new aircraft from
aircraft manufacturers as a source of new investments. In general, we focus on discerning investment value in situations that are often more
bespoke and generally less competitive.

Our Strengths

We believe that the following competitive strengths will allow us to capitalize on future growth opportunities in the global aviation
industry.

Diversified Portfolio of Modern Aircraft: We have a portfolio of modern aircraft that is diversified with respect to lessees, geographic
markets, lease maturities and aircraft types. As of December 31, 2016, we owned and managed on behalf of our joint ventures 206 aircraft,
comprising a variety of aircraft types leased to 71 lessees located in 36 countries. As of December 31, 2016, the top ten countries in which our
customers are located, ranked by percentage of our net book value, were Indonesia, Brazil, Malaysia, Chile, Thailand, India, the United
Kingdom, South Africa, Singapore and Germany. Lease expirations for our owned aircraft are well

S-3
Table of Contents
dispersed, with a weighted-average remaining lease term of 5.1 years as of December 31, 2016. This provides the company with a long-dated
base of contracted revenues. We believe our focus on portfolio diversification reduces the risks associated with individual lessee defaults and
adverse geopolitical or economic issues, and results in generally predictable cash flows.

Flexible, Disciplined Acquisition Approach and Broad Investment Sourcing Network: We consider Aircastle to be the industry's largest
"value investor." Our investment strategy is to seek out the best risk-adjusted return opportunities across the commercial jet market, so our
acquisition targets vary with market opportunities. We source our acquisitions through well-established relationships with airlines, other
aircraft lessors, manufacturers, financial institutions and other aircraft owners. Since our formation in 2004, we built our aircraft portfolio
through more than 144 transactions with 84 counterparties. During the year ended December 31, 2016, we acquired 60 aircraft for an
aggregate of approximately $1.6 billion, 28 of which were acquired for an aggregate of approximately $636 million during the fourth quarter
of 2016.

Significant Experience in Successfully Selling Aircraft Throughout Their Life Cycle: Since our formation, we sold 169 aircraft for $4.0
billion. These sales produced net gains of $231 million and involved a wide range of aircraft types and buyers. Our team is adept at managing
and executing the sale of both new and used aircraft. We sold 124 aircraft that were over 14 years old at the time of sale, with many of these
being sold on a part-out disposition basis, where the airframe and engines may be sold to various buyers. We believe our competence in
selling older aircraft is an essential portfolio management skill and one of the capabilities that sets us apart from many of our larger
competitors.

Strong Capital Raising Track Record and Access to a Wide Range of Financing Sources: Aircastle is a publicly listed company, and
our shares have traded on the New York Stock Exchange since 2006. Since our inception in late 2004, we raised approximately $1.7 billion in
equity capital from private and public investors. Our two largest shareholders are Marubeni Corporation ("Marubeni") and Ontario Teachers'
Pension Plan ("Teachers'") with whom we maintain strong, strategic relationships. We also obtained $12.9 billion in debt capital from a
variety of sources including the unsecured bond market, commercial banks, export credit agency-backed debt, and the aircraft securitization
market. The diversity and global nature of our financing sources demonstrates our ability to adapt to changing market conditions and seize
new opportunities.

Our Capital Structure Is Long-Dated and Provides Investment Flexibility: Our business is currently financed under debt financings
with a weighted-average debt maturity of 3.7 years. We also have $810 million available from unsecured revolving credit facilities that expire
https://www.sec.gov/Archives/edgar/data/1362988/000119312517074914/d350132d424b2.htm[3/9/2017 3:53:09 PM]

424B2
in 2019 and 2020, thereby limiting our near-term financial markets exposure. Given our relatively limited future capital commitments, we
have resources to take advantage of what we anticipate will be a more attractive investment environment. We also believe that our access to
the unsecured bond market and our unsecured revolving lines of credit, due to our large unencumbered asset base, allow us to pursue a flexible
and opportunistic investment strategy.

Experienced Management Team with Significant Expertise: Each member of our management team has more than 20 years of industry
experience and has expertise in the acquisition, leasing, financing, technical management, restructuring/repossession and sale of aviation
assets. This experience spans several industry cycles and a wide range of business conditions and is global in nature. We believe our
management team is highly qualified to manage and grow our aircraft portfolio and to address our long-term capital needs.

Global and Scalable Business Platform: We operate through offices in the United States, Ireland and Singapore, using a modern asset
management system designed specifically for aircraft operating lessors and capable of handling a significantly larger aircraft portfolio. We
believe that our current facilities, systems and personnel are capable of supporting an increase in our revenue base and asset base without a
proportional increase in overhead costs.

Table of Contents
Our Strategy

The overall financing environment has improved in recent years and aircraft owners have benefited from the low interest rate
environment. Particularly strong conditions in the debt capital markets have provided select borrowers, including Aircastle, access to
attractively priced, flexible financing. This provides us a competitive advantage over airlines and lessors that lack similar access. Moreover,
supply of traditional asset-based financing from commercial banks remains volatile, particularly for older aircraft. Going forward, recent
heightened financial markets volatility stemming from global growth and geopolitical concerns may increase capital costs and limit
availability. This may enable more attractive investment opportunities for Aircastle.

We plan to grow our business and profits over the long-term while maintaining a countercyclical orientation, a bias towards limiting
long-dated capital commitments and a conservative and flexible capital structure. Our business strategy entails the following elements.

Pursuing a Disciplined and Differentiated Investment Strategy. In our view, aircraft values change in different ways over time. We
carefully evaluate investments across different aircraft models, ages, lessees and acquisition sources and re-evaluate these choices as market
conditions and relative investment values change. We believe the financing flexibility offered through unsecured debt and our team's
experience with a wide range of asset types enables our value oriented strategy and provides us with a competitive advantage. We view orders
from equipment manufacturers to be part of our investment opportunity set, but choose to limit long term capital commitments unless we
believe there is an adequate return premium to compensate for risks and opportunity costs. This approach sets us apart from most other large
aircraft leasing companies.

Originating Investments from Many Different Sources Across the Globe. Our strategy is to seek out worthwhile investments by
leveraging our team's wide range of contacts around the world. We utilize a multi-channel approach to sourcing acquisitions and have
purchased aircraft from a large number of airlines, lessors, original equipment manufacturers, lenders and other aircraft owners.

Leveraging Our Strategic Relationships. We intend to capture the benefits provided through the extensive global contacts and
relationships maintained by Marubeni, which is our biggest shareholder and one of the largest Japanese trading companies. Marubeni has
already enabled greater access to Japanese-based financing and helped source and develop our new joint venture ("IBJ Air") with the leasing
arm of the Industrial Bank of Japan, Limited. Our Lancaster joint venture with Teachers' provides us with an opportunity to pursue larger
transactions, manage portfolio concentrations and improve our return on deployed capital. IBJ Air is targeted at newer narrow-body aircraft
leased to premier airlines, providing Aircastle with increased access to this market sector and to these customers.

Maintaining Efficient Access to Capital from a Wide Set of Sources While Targeting an Investment Grade Credit Rating. We believe
the aircraft investment market is influenced by the business cycle. Our strategy is to increase our purchase activity when prices are low and to
emphasize asset sales when competition for assets is high. To implement this approach, we believe it is important to maintain access to a wide
variety of financing sources. Our strategy is to improve our corporate credit ratings to an investment grade level by maintaining strong
portfolio and capital structure metrics while achieving a critical size through accretive growth. We believe improving our credit rating will not
only reduce our borrowing costs but also facilitate more reliable access to both secured and unsecured debt capital throughout the business
cycle.

Selling Assets When Attractive Opportunities Arise and for Portfolio Management Purposes. We sell assets with the aim of realizing
profits and reinvesting proceeds when more accretive investments are available. We also use asset sales for portfolio management purposes,
