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 July 21, 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.

Prospectus Summary, page 1 - -------------------------- 1. We read your response to comment 7 of our letter June 28, 2006. We also note the statement in the fourth sentence of the first paragraph in the section entitled Aircastle Limited July 25,2006 Page 2 of 5 "Aircastle Limited" that you are obligated to pay...maintenance or modification costs "in some cases." Please reconcile this statement with the disclosure in the second sentence of the last paragraph on page 85 that you are required to bear a portion of the maintenance or modification costs under "many" of your leases. In addition, please discuss the maintenance payments and end of lease payments the lessee is required to pay under all of your leases, which are reflected in Note 2 to your audited financial statements. It is unclear to us whether the amounts that you are obligated to pay in "some cases" or under "many" of your leases are: o portions of these maintenance payments that you return to the lessees after they have fully performed the maintenance at their expense, o amounts that you pay, either out of the payments or in excess of the payments, to perform maintenance that the lessee fails to perform, o amounts that are necessary to cover maintenance that the lease requires the company to perform, or o some other amount.

Financial Statements - -------------------- Unaudited Consolidated Pro Forma Financial Statements - ----------------------------------------------------- 5. It appears that different terminology is being used to refer to the same pro forma amounts.

Please clarify whether these amounts are the same. If so, please use the same terminology to refer to them. If these amounts are different, please clarify how they are different and why you are presenting two different sets of pro forma amounts. The disclosure has been revised in response to the Staff's comment to use consistent column headings throughout the prospectus, including on page 43 and in the unaudited consolidated pro forma financial statements.

Each adjustment should disclose the amount of each loan being repaid or issued Aircastle Limited July 25,2006 Page 4 of 5 multiplied times its interest rate and arrive at the amount of interest expense to be deducted or added in the pro forma adjustment.
