                  -----------------------------------------------------

Dear Ms. Long:

                  On behalf of Aircastle Limited, a Bermuda exempted company
(the "Company"), enclosed is a copy of Amendment No. 1 to the above-referenced
Registration Statement (the "Registration Statement"), as filed with the
Securities and Exchange Commission (the "Commission") on the date hereof, marked
to show changes from the Registration Statement on Form S-1 filed with the
Commission on June 2, 2006.

                  The changes reflected in the Registration Statement include
those made in response to the comments (the "Comments") of the staff of the
Commission (the "Staff") set forth in the Staff's letter of June 28, 2006 (the
"Comment Letter"). The Registration Statement also includes other changes that
are intended to update, clarify and render more complete, the information
contained therein.

                  Set forth below in this letter are the Company's responses to
the Comments raised in the Comment Letter. For the convenience of the Staff, the
Company has restated in this letter each of the Comments in the Comment Letter
and numbered each of the responses to correspond with the numbers of the
Comments in the Comment Letter. Capitalized terms used and not defined have the

         containing pricing-related

         information. Since this information affects a number of disclosure
         items, you should allow a reasonable time for our review prior to
         requesting acceleration. In the course of our review we may raise
         issues relating to matters we had not previously commented upon. In
         addition, please be advised that you may not circulate copies of your
         prospectus until you have included an estimated price range and all
         other information required by the federal securities laws, except
         information you may exclude in reliance upon Rule 430A of Regulation C.

                  The Company will include the information identified in Comment
         No. 1 in a subsequent amendment to the Registration Statement prior to
         circulating a preliminary prospectus. The pre-effective amendment with
         the pricing-related information will be filed with the Commission to
         give the Staff sufficient time to review such information, and the
         Company notes that the Staff may have additional comments once such
         pre-effective amendment is filed.

2.       Please provide us with copies of any artwork or other graphics you
         intend to use in your prospectus. Please be advised that we may have
         comments and you may want to consider waiting for our comments before
         printing and circulating these materials.

                  Copies of all artwork to be contained in the prospectus will
         be supplementally submitted to you as soon as practicable and prior to
         circulating preliminary prospectuses. The Company notes that the Staff
         may have comments that could result in material revisions to the
         Company's artwork.

3.       We note the comparative and factual assertions throughout your
         prospectus as to information related to your industries. Please advise
         us as to whether your basis for these assertions is based on the most
         recently available data and, therefore, is reliable. In addition, if
         you funded or were otherwise affiliated with any sources that you cite,
         please disclose this fact. Otherwise, please confirm to us that your
         sources are widely available to the public. If any of the sources are
         not publicly available, please either file consents or explain to us
         why you are not required to do so under Rule 436 of Regulation C and
         Section 7 of the Securities Act.

                  In response to the Staff's comment, the Company has filed
         consents as Exhibits to the Registration Statement. The Company
         supplementally advises the Staff that the Company believes that its
         assertions are based on current available data and the Company has not
         funded and is not affiliated with any of the sources cited in the
         prospectus.

         set forth in your prospectus. If you intend to use any free writing
         prospectuses, you should remove this statement when you have a Section
         10 prospectus available, as you will be liable for and investors will
         be entitled to rely upon that information.

         dividends" or demonstrate your ability to pay predictable dividends.
         Please also clarify what you mean by the term "predictable."

                  The disclosure on pages 1-2 has been revised in response to

10.      We note the disclosure in the last sentence of the third paragraph. We
         also note similar disclosure elsewhere in your prospectus, including in
         risk factor eight on page 13 and in the section entitled "Dividend
         Policy" on pages 6 and 42. Please disclose, if true, that the dividend
         paid in 2006 is not indicative of the amount of dividends you will pay
         in the future.

                  The disclosure on pages 2, 5, 12 and 39 has been revised in
         response to the Staff's comment.

         to the Staff's comment.

Scaleable business platform, page 2
- -----------------------------------

         systems are "state-of-the-art." Please also explain how the platform

                  The disclosure on pages 2 and 82 has been revised to replace
         the term "state-of-the-art" with a term which the Company believes to
         be a better description of its asset management systems, and to explain
         how the platform design enables the Company to grow its revenues and
         asset base without a proportional increase in costs.

Innovative long-term debt financing structure, page 2

         response to the Staff's comment.

Industry Trends, page 3
- -----------------------

Improving lease rates, page 4

         rate factors. For example, will lessees consider purchasing than
         leasing if the factor is too high?

                  The disclosure on page 3 has been revised in response to the
         Staff's comment.

Recent Securitization, page 4
- -----------------------------

17.      Please explain "securitization" as investors may not be familiar with
         this type of financing. Please also explain what you mean by "fixed
         rate financing cost."

                  The disclosure on page 1 has been revised in response to the
         Staff's comment.

Summary Consolidated Financial Information, page 8
- --------------------------------------------------

18.      Please provide an additional column to your capitalization table in
         note 2, which is labeled as further adjusted or something similar.
         Similar to the capitalization table on page 43, the additional column
         should include the effects of your offering; whereas, the adjusted pro
         forma column should show the pro forma effects of all other adjustments
         excluding your offering.

                  The disclosure on page 9 has been revised in response to the
         Staff's comment.

Risk Factors, page 11
- ---------------------

19.      Please delete the last sentence of the introductory paragraph. In this
         regard, we note that you must disclose all risks you believe are
         material at this time and may not qualify your disclosure by referring
         to unknown risks or risks that may become material. Refer to Staff
         Legal Bulletin No. 7A, sample comment #30.

                  The disclosure on page 10 has been revised in response to the
         Staff's comment.

20.      Please revise your risk factors to remove the phrases "we cannot
         assure," "there can be no assurance," and other similar phrases. In
         this regard, we note that the




Aircastle Limited

         actual risk is that the event will occur, not your inability to prevent
         it. See, for example and without limitation, risk factors one, eight,
         10, 16, 20, 22, 24, 26, 28, 31, 36, 45, 46, 54 and 55.

                  The disclosure in the "Risk Factors" section has been revised
         in response to the Staff's comment.

21.      Many of your risk factors in this section are repetitive, in that they
         repeat risks and/or disclosure discussed elsewhere in this section.
         Your risk factors should describe a genuine risk which is prominently
         expressed with only enough other information included to place the risk
         in context. Please review all of your risk factors and revise
         accordingly.

                  The disclosure in the "Risk Factors" section has been revised
         in response to the Staff's comment.

22.      Item 503(c) of Regulation S-K states that issuers should not "present
         risk factors that could apply to any issuer or any offering." Certain
         of your risk factors could apply to many issuers in your industry and
         in other industries. See, for example, risk factors three, nine, 11,
         13, 16, 24 and 57. Please explain how these risk factors specifically
         apply to your company or your offering.

                  The Company has deleted risk factors 3, 9, 13 and 57 and
         revised risk factors 16, 24 and others in response to the Staff's
         comment. The Company believes that risk factor 11 is specifically
         relevant to the Company's operations.

An increase in our borrowing costs..., page 13
- ----------------------------------------------

23.      Please discuss your annual debt obligations and the impact of a 1%
         increase in interest rates on these obligations.

         In response to the Staff's comment, the Company has revised the
disclosure on pages 11 and 12 to include the impact of a 1% increase in interest
rates on the Company's debt obligations.

Departure of key officers..., page 13
- -------------------------------------

24.      All companies rely on their key personnel. Please explain how this
         specific risk applies to your company. For example, do you lack
         employment contracts with any of your key personnel? Are any of your
         key personnel planning to retire or nearing retirement age?

                  The Company has revised the disclosure on page 12 to clarify
         how the risk applies to the Company.

The concentration of aircraft types..., page 17
- -----------------------------------------------

25.      Please clarify the risk discussed in the first sentence of the second
         paragraph.

                  The disclosure on pages 15 and 16 has been revised in response
         to the Staff's comment.

If the ownership of our common shares..., page 31
- -------------------------------------------------

26.      Please revise to disclose the actual risk to an investor, namely the
         risk that your controlling stockholder may prevent or frustrate
         attempts to effect a transaction that is in the best interests of other
         stockholders, or may cause your company to take action that is not in
         the best interests of other stockholder. Please comply with this
         comment in risk factor 43.

                  The disclosure on pages 28-29 has been revised in response to
         the Staff's comment.

Market and Industry Data and Forecasts, page 40
- -----------------------------------------------

27.      We note the statements in the last sentence of each of the second and
         third paragraphs regarding the fact that certain information has not
         been verified. Please be advised that you are responsible for the
         entire content of your prospectus and cannot include language that may
         be interpreted as a disclaimer of the information in your prospectus.
         Please revise to remove these statements.

                  The disclosure on page 37 has been revised in response to the
         Staff's comment.

Use of Proceeds, page 41
- ------------------------

28.      Please revise the third sentence of the first paragraph to disclose the
         amount of proceeds that will be used to repay indebtedness. Please also
         comply with this comment in the section entitled "Use of Proceeds" on
         page 6.

                  The Company currently is unable to calculate how much debt
         will be outstanding under Credit Facility No. 2 upon the completion of
         this offering and therefore is unable to quantify the amount of
         proceeds that will be used to repay indebtedness. Credit Facility No. 2
         is a revolving credit facility pursuant to which the Company may borrow
         additional funds at any time up to a maximum amount. However, the
         Company will disclose the amount of proceeds that will be used to repay
         indebtedness in "Use of Proceeds" section in a subsequent amendment to
         the Registration Statement prior to the time the preliminary prospectus
         is circulated to potential investors.

29.      We note the disclosure in the last paragraph. Please explain the
         circumstances under which you would use a portion of the proceeds to
         acquire aviation assets. See Instruction 7 to Item 504 of Regulation
         S-K. Please also state the amounts and sources of other funds needed to
         acquire these assets, as it appears that material amounts of other
         funds will be necessary for this propose. See Instruction 3 to Item 504
         of Regulation S-K.

                  The disclosure on page 38 has been revised in response to the
         Staff's comment.

Dividend Policy, page 42
- ------------------------

30.      You state that you expect to pay substantially all of your earnings to
         your stockholders as dividends. Please disclose in greater detail what
         this means. Please provide the following disclosures regarding your
         dividend policy:

         o        Please discuss the risks and limitations of your policy. This
                  should include a clear statement that your dividends may not
                  be paid in accordance with your policy. You should also
                  disclose the consequences of not investing your earnings in
                  future growth as well as the consequences of not using your
                  earnings towards provisions for unexpected cash needs;

         o        Please disclose whether you intend to borrow to pay dividends
                  according to your stated policy if you do not have the cash
                  necessary to pay the intended dividends, as well as the risks
                  and possible outcomes if expected results are not achieved;
                  and

         o        You disclose that certain current debt arrangements restrict
                  you from paying dividends after your offering if you are in
                  default. Please state whether based on your forward-looking
                  operating results and expected cash flows, you expect to be in
                  compliance with these debt covenants, for which noncompliance
                  could lead you to be in default.

                  The disclosure on pages 1, 5 and 39 has been revised in
         response to the Staff's comment.

31.               We note the disclosure in the first paragraph. Please explain
         how you intend to finance this dividend.

         include any shares that your officers, directors, and affiliated
         persons have the right to acquire. Please revise accordingly. See Item
         506 of Regulation S-K.

                  The Company supplementally informs the Staff that no officers,
         directors and affiliated persons have the right to acquire any shares.

         the disclosure on page 50 to eliminate the term "residual economic
         interests" and to clarify its remaining economic interests in Portfolio
         No. 1.

34.      We note the disclosure in the first sentence of the third paragraph.
         Please explain what you mean by "pool balance of the certificates."

                  In response to the Staff's comment, the Company has deleted
         the reference to "pool" balance throughout the prospectus and replaced
         it with "outstanding principal balance" of the certificates or similar
         terms to clarify the disclosure.

Revenues and Contribution Margin, page 53
- -----------------------------------------

35.      Your current presentation of total contribution margin appears to
         constitute a non-GAAP financial measure. Please remove the total
         amounts, or provide the disclosures required by Item 10(e) of
         Regulation S-K. Refer to Question 21 of our FAQ Regarding the Use of
         Non-GAAP Financial Measures dated June 13, 2003.

                  In response to the Staff's comment, the Company has revised

Foreign Currency Risk and Foreign Operations, page 67
- -----------------------------------------------------

40.      It appears that the US Dollar is the functional currency for all of
         your operations. Given that you have branch offices in Ireland and
         Singapore, you incur Euro and Singapore dollar denominated expenses,
         and the majority of your revenues recorded are denominated from Europe
         and Asia, please tell us how you determined it is appropriate to use
         the US Dollar as the functional currency for your offices and
         operations in Ireland and Singapore in accordance with paragraphs 5
         through 10 of SFAS 52.

                  The Company advises the Staff that it has determined that the
         functional currency of the branch offices in Ireland and Singapore are
         the same as the parent's (the Company's) functional currency as the
         foreign operations are a direct and integral component or extension of
         the parent company's operations as defined in paragraph 5 of SFAS 52.
         Significantly, all Company revenues (including branch revenues), except
         one Euro denominated lease, are denominated in US Dollars. All Company
         debt and interest expenses are denominated in US Dollars. All aircraft
         purchases are denominated in US Dollars. The remaining local currency
         expenses are not material.

         Staff's comment.

56.      We note the statement in the second sentence of the introductory
         paragraph that the summaries are not complete. A summary by its nature

         or all aspects of Delaware law which may differ from Bermuda law." A

Flight Equipment Held for Lease, page F-8
- -----------------------------------------

74.      You state that lessee specific modifications are capitalized and
         depreciated over the life of the related lease and included in other
         assets. Please address the following related to these amounts:

         o        Please disclose the amounts capitalized at December 31, 2005
                  and March 31, 2006;

         o        Please tell us the nature of these lessee specific
                  modifications;

         o        Please tell us how you determined it is appropriate to record
                  these modifications as an asset on your financial statements;
                  and

         o        Please disclose whether you are treating these amounts as
                  lease incentives in accordance with FTS 88-1.

                  The disclosures on pages F-15, F-16 F-20 and F-37 have been
         revised in response to the Staff's comment.

                  The Company advises the Staff that lease acquisition costs
         consisted primarily of $775,382 of flight equipment installed on the
         aircraft. Flight equipment installed on the aircraft at the request of
         the current lessee is capitalized and amortized into expense over the
         life of the initial lease, assuming no renewals in accordance. Examples
         of flight equipment are additional avionics and reconfiguration of the
         aircraft cabin.

                  Prepaid lease incentive costs consisted of $442,529 of cash
         incentive paid to a lessee. The cash incentive paid to a lessee is
         capitalized and amortized into revenue over the life of the initial
         lease, assuming no renewals, in accordance with FTB 88-1.

75.      Please disclose whether you assume lease renewals in your determination
         of lease term in accordance with paragraph 5.f. of SFAS 13 for purposes
         of amortizing lease specific modifications and lease premiums.

                  The disclosure on pages F-15 and F-16 has been revised in
         response to the Staff's comment.

76.      Please disclose how you account for (a) step rent provisions and
         escalation clauses and (b) capital improvement funding and other lease
         concessions, which may be present in your leases. In addition,
         paragraph 5.n. of SFAS 13, as amended by SFAS 29, discusses how lease
         revenues that depend on an existing index or rate, such as the consumer
         price index or the prime interest rate, should



Aircastle Limited
July 7, 2006
Page 18 of 28

          be initially included in your minimum lease revenues. If, as we
          assume, each of these items is included in computing your minimum
          lease revenues and the minimum lease revenues are recognized on a
          straight-line basis over the minimum lease term, the note should so
          state. If our assumption is incorrect, please tell us how you
          considered the provisions in SFAS 13 and FTB 88-1 in reaching the
          conclusions you did regarding your accounting treatment.

                  The disclosure on page F-18 has been revised in response to
         the Staff's comment.

                  The Company advises the Staff that it has three types of
         rental provisions; (1) fixed rate leases, (2) floating rate leases and
         (3) step rent leases. Fixed rate leases and step rent leases are
         recognized on a straight-line basis over the term of the lease.
         Floating rate leases are indexed to LIBOR and rents are adjusted
         prospectively for 6-month periods. For determination of the lease as an
         operating lease under FAS 13, the floating rate lease is included in
         the minimum lease payments using LIBOR at inception of the lease to
         calculate the minimum lease payments. For recognition of revenue under
         FAS 13 and in accordance with SAB 104, revenues are recognized on a
         straight-line basis over the period the floating rentals are fixed and
         accruable.

                  The Company advises the Staff that it has no capital
         improvement funding and no rental escalation clauses in its leases.
         Please see the Company's responses to Comment Nos. 71-73 for a
         discussion of other lease concessions.

         including the original terms, renewal periods, and other typical

         23 (b) and (c) of SFAS 13.

                  The disclosure on page F-18 has been revised in response to
         the Staff's comment.

                  The Company advises the Staff that it has no contingent rents.

78.      Please provide us with an analysis of all equity issuances since

         restricted shares made to employees in February and March 2006, the
         purchases of restricted shares by executive officers in April 2006, and
         the purchases of common shares by employees and a director in May 2006.

                           or retrospective.

                  o        To the extent applicable, reconcile the fair values
                           you used for equity transactions to the fair value
                           indicated by the anticipated IPO price.

         For equity transactions in which you and your board of directors
         estimated the fair value, please provide us with a detailed explanation
         of the significant factors, assumptions, and methodologies used in
         determining fair value. We will not be able to complete our evaluation
         of your response until the IPO range has been disclosed.

                  Please see the schedule entitled "Shareholder Transactions
         January to May 2006" attached hereto as Exhibit A for an analysis of
         all equity issuances since January 1, 2006 and a detailed explanation
         of the significant factors, assumptions and methodologies used in
         determining the fair value.

                  The Company supplementally informs the Staff that, subject to
         additional analysis and market conditions, the IPO range is estimated
         to be $19-22 per share.

                  The fair value of the shares purchased was determined based on
         a valuation performed by management of the Company and approved by the
         Board of Directors. The valuation involved projecting the Company's
         earnings through the date of the anticipated IPO to develop an
         estimated annualized rate of earnings and annualized earnings and
         dividends per share based on the following:

                  a)       The Company projected its aircraft assets in the
                           amount of $1,674.0 million by taking its existing
                           owned aircraft at March 2006 in the amount of $966.0
                           million plus $608 million of estimated aircraft
                           purchases with signed purchase agreements and letters
                           of intent plus an assumed $100 million acquisition
                           rate for new deals starting in June 2006.

                  b)       July revenue was projected based on the aircraft
                           assets owned as of July 2006 resulting in a projected
                           monthly lease rent of $19.4 million plus interest on
                           investments of $1.0 million for a total of $20.4
                           million of total revenue for the month of July.

                  c)       Based on the July monthly revenues, the Company
                           calculated its annualized revenues in the amount of
                           $244.8 million.

                  d)       Taking into account our annual depreciation expense
                           of aircraft assets, our annual interest expense as
                           adjusted for the proceeds of the IPO, and our annual
                           cash selling, general and administration expenses,
                           the Company estimated its projected adjusted net
                           income to be $72.2 million.

                  e)       The Company projected its outstanding shares by
                           taking its March 2006 outstanding shares in the
                           amount of 44.4 million minus the return of capital
                           and shares to Fortress in the amount of 3.7 million
                           shares plus 0.3 million of shares purchased by
                           employees and a director plus 9.9 million of shares
                           issued in the IPO resulting in a projected 50.9
                           million of shares outstanding at July 2006.

                  f)       The Company calculated its earnings per share by
                           taking the projected adjusted net income of $72.2
                           million divided by the projected 50.9 million shares
                           outstanding to arrive at annualized $1.42 earnings
                           per share.

                  g)       The Company calculated the implied share price at the
                           IPO by multiplying the annualized $1.42 EPS by an
                           estimated P/E ratio of 14.3x, which equates to a
                           yield of 7%.

         transaction during each period presented including, but not limited to,

                  such.

         how you differentiate whether depreciation, other expenses, and
         interest income amount should or should not be allocated to reportable
         segments. See paragraphs 31 and 32 of SFAS 131.

                  The disclosures on pages F-28 and F-44 have been revised

         as applicable.

                  The disclosures with respect to the Company's interim
         financial statements have been revised, where applicable, in response
         to the Staff's comment.

Statements of Cash Flows, page F-26
- -----------------------------------

83.      In Note 2 on page F-8 you state that restricted cash and cash
         equivalents consists primarily of maintenance deposits received from
         lessees pursuant to the terms of various lease agreements and rent
         collections held in lockbox accounts pursuant to our credit facilities.
         In light of this, please tell us the nature of the line item described
         as restricted cash from disposition of flight equipment held for sale,
         and how you determined it was appropriate to classify this as cash
         flows from investing activities in accordance with paragraph 17 of SFAS
         95.

                  The disclosure on page F-37 has been revised in response to
         the Staff's comment.

                  The Company advises the Staff that it believes the
         classification of the proceeds of the sale of the aircraft represent an
         investing activity as described in paragraph 16c of SAS No. 95 as
         opposed to operating or financing activities. In this instance, under
         the terms of the related credit facility the proceeds from the



Aircastle Limited

          sale of the aircraft of $57,157 million were initially deposited into
          a restricted cash account from which the lender withdrew the required
          debt repayments of $36,666 million. However, due to the timing of the
          transaction the balance of $20,325 million was retained in the
          restricted cash account until April 2006 when it was transferred to an
          unrestricted operating cash account. Accordingly, the Company
          presented the net activity in the restricted cash account as an
          investing activity as it does not represent an operating activity as
          described in paragraph 23 of SFAS No. 95 as the proceeds related to
          the sale of an aircraft which is an investing activity. The restricted
          cash activity related to this specific transaction is of a different
          nature than the activities underlying the change in the restricted
          cash and cash equivalents reflected in the operating activities
          section of the Company's statement of cash flows. The Company believes
          this presentation allows the reader to understand the change in the
          total restricted cash account for the three month period ended March
          31, 2006.

         exemption in Rule 701 under the Securities Act with respect to the
         transactions set forth under the heading "Stock Option Grants and
         Grants of Restricted Shares."

                  The Company's grants and sales of restricted shares in 2006
         were made in reliance on Rule 701 of the Securities Act, as the Company
         was not subject to the reporting requirements of Section 13 or 15(d) of
         the Securities Exchange Act of 1934 at the time the share grants and
         share sales were made pursuant to our 2005 Equity Incentive Plan, a
         copy of which was made available to each recipient of common shares in
         connection with the transactions, and the aggregate sales price (or
         fair market value of the grants) of the common shares issued during any
         consecutive 12-month period in reliance of Rule 701 did not exceed 15%
         of our total assets, measured as of our most recent balance sheet date.

         Registration Statement as part of Amendment No. 1. The Company will

     *   As disclosed in footnote 8 in the March 31, 2006 Unaudited Consolidated
         Financial Statements, the fair value of the restricted shares granted
         in 2006 was determined based on a retrospective valuation performed by
         management of the Company and approved by the Board of Directors. The
         valuation involved projecting the Company's earnings through the date
         of the anticipated IPO to develop an estimated annualized rate of
         earnings and annualized earnings and dividends per share. Key
         assumptions used in developing the projection included expected monthly
         acquisition volume through the anticipated IPO date, leverage and
         interest costs, revenues from new aircraft acquisitions and the growth
         of selling, general and administrative expenses.

         Financial Statements, excludes 372,500 restricted shares granted in
         2005 that were issued in February 2006 of which 347,500 were granted in
         first half of 2005 and 25,000 shares were granted on July 5, 2005 under
         various employment contracts accounted for under FAS 123R. The fair
         value of the restricted shares granted in 2005 was determined to be

         investments made by the Shareholders, adjusted to reflect the lack of
         marketability of the shares granted to employees. Excludes 3,693,200
         shares purchased in February 2006 at $10 per share in accordance with
         the Second Amended Sharehoulders' Agreement.
