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 July 7, 2006 Page 6 of 28 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.

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.

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. Note 4.

Shareholders' Equity, Share Based Payments and Earnings (Loss) Per Share, page F-18 - ------------------------------------------------------------------------ 78. Please provide us with an analysis of all equity issuances since January 1, 2006. These issuances should include the grants of 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. For each transaction: o identify the parties, including any related parties; Aircastle Limited July 7, 2006 Page 19 of 28 o the nature of the consideration; and o the fair value and your basis for determining the fair value. o Indicate whether the fair value was contemporaneous 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. Aircastle Limited July 7, 2006 Page 20 of 28 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%. 79. Please provide more detailed disclosures regarding each equity transaction during each period presented including, but not limited to, the following: o The reason for the issuance; o The consideration received by you, if any; o The fair value of the securities issued; o Number of shares granted; o Exercise price; o Fair value of common stock; o The existence of any conversion or redemption features; o Whether the valuation used to determine the fair value of the equity instruments was contemporaneous or retrospective; and o If the valuation specialist was a related party, indicate as such.

Financial Statements for the Three Months Ended March 31, 2006 - -------------------------------------------------------------- General - ------- 82. Please address the comments above in your interim financial statements, 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 July 7, 2006 Page 23 of 28 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.

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. *** As disclosed in footnote 13 in the December 31, 2005 Consolidated 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 $8.50 per share based on a retrospective valuation performed by an unrelated valuation specialist. The valuation relied on observed equity 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.
