SECTION 1 -- REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

SECURITIZATION

GENERAL. On June 1, 2007, Aircastle Limited ("Aircastle") issued a press release
which was filed as Exhibit 99.1 to the Company's Current Report on Form 8-K,
filed June 1, 2007, and which is incorporated herein by reference, announcing
that the ACS 2007-1 Pass Through Trust (the "Trust") priced a single tranche of
$1,170,000,000 of Class G-1 Floating Rate Asset Backed Certificates, series
2007-1 (the "Certificates"). The Certificates bear interest on a floating rate
basis at the rate of one-month LIBOR plus 0.26%.

The Trust will purchase Class A-1 Notes ("Notes") issued by subsidiaries of
Aircastle, ACS 2007-1 Limited and ACS Aircraft Finance Ireland 2 Limited (the
"Note Issuers"), which will use the proceeds of the sale of the Notes to acquire
a portfolio expected to consist of 59 aircraft from affiliates of Aircastle. The
Notes also bear interest at the rate of one-month LIBOR plus 0.26% and the Note
Issuers have entered into interest rate swaps fixing the rate for five years.
These swaps, together with the guarantee premium and other costs of trust
administration, result in an estimated fixed rate cost of 6.20 % per annum,
after the amortization of issuance fees and expenses. Aircastle will hold
substantially all the equity interests in the Note Issuers, and will consolidate
the results of the Note Issuers with Aircastle's results. Aircastle, ACS 2007-1
Limited and ACS Aircraft Finance Ireland 2 Limited, together with their
respective subsidiaries, are referred to herein as the ACS-2 Group.

In connection with the closing of the sale of the Certificates on June 8, 2007,
Aircastle entered into two trust indentures. The following summary of certain
provisions of the trust indentures is qualified in its entirety by reference to
the complete trust indentures filed as Exhibits 10.1 and 10.2 hereto and
incorporated herein by reference.

LIQUIDITY. The ACS-2 Group will be required to maintain, as of each monthly
payment date, unrestricted cash in an amount sufficient to cover its operating
expenses over the one month, or in the case of maintenance expenditures, the
three months following such payment date. In addition, HSH Nordbank AG, New York
branch, provided a liquidity facility to the ACS-2 Group in the initial amount
of $87.75 million and thereafter the greater of (a) 7.5% of the outstanding
principal amount of the Notes and (b) $65 million, which may under certain
circumstances be drawn upon to pay expenses of the ACS-2 Group, interest rate
swap payments and interest on the Notes.

SERVICING. Aircastle's wholly-owned subsidiaries, Aircastle Advisor LLC and
Aircastle Advisor (Ireland) Limited provide lease remarketing and other services
to the ACS-2 Group entities and each receives a fee equal to 2.0% of the
aggregate rentals received in relation to the aircraft it is remarketing and, in
the case of Aircastle Advisor (Ireland) Limited, 1.0% of the net sales proceeds
of any aircraft sold. Aircastle Advisor LLC also provides administrative
services to the ACS-2 Group entities and is paid an annual fee equal to 0.5% of
the aggregate rentals received each month on the ACS-2 Group aircraft.


                                       2



The remarketing services and administrative agency agreements may be terminated
in certain circumstances by the ACS-2 Group or the financial guaranty insurance
policy provider in the event of a default by or insolvency of any of the
remarketing servicers or administrative agents,, and in addition the remarketing
servicers may be terminated if, among other things, (i) at least 15% of the
aircraft of the ACS group remain off-lease for four months or more after having
been reasonably available for lease, (ii) Aircastle's tangible net worth falls
below $250 million, (iii) Aircastle's leverage ratio exceeds 8.5, or (iv)
Fortress Investment Group LLC and its affiliates ("Fortress") fail to maintain a
10% ownership interest in Aircastle until the fifth anniversary of the closing
date unless Aircastle's net worth is at least $600 million; provided, however,
that the foregoing will not be a termination event if Fortress has not sold any
shares of Aircastle.

International Lease Finance Corporation as agreed to act as the back-up
remarketing servicer and will provide remarketing services if the remarketing
service agreements terminate prior to repayment of the Notes. In addition to
monthly stand-by fees, the back-up remarketing servicer would receive, upon the
termination of the remarketing services agreements, an additional monthly
rent-based fee equal to 3.0% of the aggregate rents received on the ACS-2 Group
aircraft and a sales-based incentive fee with respect to each aircraft sale in
the amount of 3.0% of the value of the total consideration paid by the buyer.

INTEREST RATE. The Notes will bear interest at one-month LIBOR plus 0.26%. The
Note Issuers have entered into an interest rate swaps intended to hedge the
interest rate exposure associated with issuing floating-rate obligations backed
by primarily fixed-rate lease assets. These swaps, together with the guarantee
premium, the spread referenced above and other costs of trust administration,
result in an estimated fixed rate cost of 6.20% per annum, after the
amortization of issuance fees and expenses.

PAYMENT TERMS. The interest and principal payments on the Notes are due on a
monthly basis. The scheduled payments of principal have been calculated such
that the principal balance of the Notes will be equal to 60.6% of the lesser of
the mean and median of base value appraisals obtained from three internationally
recognized appraisal firms as of December 31, 2006 ("Initial Appraised Value")
as such Initial Appraised Value is decreased over time by an assumed amount of
depreciation. During the first five years of the transaction, subject to
compliance with the debt service coverage ratio test in years four and five, all
cash flows attributable to the underlying aircraft after payment of expenses,
interest and scheduled principal payments, or excess securitization cash flows,
will be available for distribution to Aircastle. Aircastle intends to use the
excess securitization cash flow to pay dividends or for other purposes.
Aircastle expects to refinance the Notes on or prior to June 2012. In the event
that the Notes are not repaid on or prior to June 2012, the excess
securitization cash flow will be used to repay the principal amount of the Notes
and will not be available to Aircastle to pay dividends to its shareholders or
for other purposes. If during year four or five of the transaction, the debt
service coverage ratio test fails on two consecutive payment dates, the excess
securitization cash flow will thereafter be used to repay the principal amount
of the Notes and will not be available to Aircastle to pay dividends to its
shareholders or for other purposes. The debt service coverage ratio test will
fail to the extent that the trailing six month debt service coverage ratio is
less than 1.7:1.

If the Notes are voluntarily redeemed, other than in certain limited
circumstances, the redemption price will be 103% of the then-outstanding
principal balance of the Notes, if the


                                       3


redemption occurs in the first ten months following the closing of the
securitization. The redemption price reduces to 102% during the period between
11 and 20 months following closing, and to 101% in the period between 21 and 30
months following closing, and 100% thereafter. A redemption premium would also
be payable to the financial guaranty insurance policy issuer in the event of a
voluntary redemption prior to the third anniversary of the closing date, and the
financial guaranty insurance policy issuer's monthly premium will increase if
the Certificates are not fully repaid within 72 months of the closing date.

MATURITY DATE. The final maturity date is June 8, 2037. Aircastle intends to
refinance the Certificates on or before June 2012.

COLLATERAL. The property of the trust includes the Notes and rights under the
financial guaranty insurance policy. The Notes are secured by first priority
perfected security interests in and pledges or assignments of equity ownership
and beneficial interests in certain ACS-2 Group entities, as well as by their
interests in leases of the aircraft they own, by cash held by or for them and by
their rights under agreements with the service providers. Rentals and reserves
paid under leases of the ACS-2 Group aircraft will be placed in collection
accounts and paid out according to a priority of payments.

DEFAULT AND REMEDIES. Aircastle, ACS 2007-1 Limited and ACS Aircraft Finance
Ireland 2 Limited will be in default under the transaction documents in the
event that, among other things, interest on the Notes or principal due at final
maturity is not paid, certain other covenants are not complied with and
noncompliance materially adversely affects the noteholder, any significant ACS-2
Group member becomes the subject of insolvency proceedings or a judgment for the
payment of money exceeding five percent of the then assumed aircraft portfolio
value is entered and remains unstayed for a period of time. Following any such
default and acceleration of the Notes by the controlling party, the security
trustee may exercise such remedies in relation to the collateral as may be
available to it under applicable law, including the sale of any of the aircraft
at public or private sale and on such terms as it may determine to be
commercially reasonable. After the occurrence of certain bankruptcy and
insolvency related events of default, or any acceleration of the Notes after the
occurrence of any event of default, all cash generated by the ACS-2 Group will
be used to prepay the Notes and will not be available to Aircastle to make
distributions to its shareholders or for other purposes.

CERTAIN COVENANTS. The transaction documents contain other operating covenants
applicable to the ACS-2 Group entities, including covenants that restrict the
investment and business activities of the ACS-2 Group, limit the amount of debt
that can be assumed by the ACS-2 Group entities and the payments they may make
outside the payment priority provisions of the transaction documents, restrict
their ability to grant liens, and limit their ability to merge, amalgamate,
consolidate or transfer assets.
