         RE:      Aircastle Limited
                  Amendment No. 2 to Registration Statement on Form S-1
                  (File No. 333-134669)
                  -----------------------------------------------------

Dear Ms. Long:

                  On behalf of Aircastle Limited, a Bermuda exempted company
(the "Company"), enclosed is a copy of Amendment No. 2 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 Amendment No. 1 to the Registration Statement on Form S-1
filed with the Commission on July 10, 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 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. Capitalized terms used and not defined have the
meanings given in the Registration Statement. All references to page numbers and
captions correspond to the page numbers and captions in the preliminary
prospectus included in the Registration Statement.


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.

               The disclosure on pages 1, 48, 83 and 88-89 has been revised in
          response to the Staff's comment.

Recent Developments, page 3

Second Quarter Financial Results, page 4
- ----------------------------------------

     2.   It appears that you intend to present EBITDA for the quarter ended
          June 30, 2006. If so, please also provide all of the disclosures
          required by Item 10(e) of Regulation S-K, or refer to the location
          elsewhere in the filing where they are located.


               The Company has revised the disclosure on page 4 in response to
          the Staff's comment to provide a reconciliation of EBITDA to net
          income and a cross-reference to the disclosures required by Item
          10(e) of Regulation S-K.


Dividend Policy, page 39
- ------------------------

     3.   We read your response to comment 30 of our letter dated June 28, 2006
          and we reissue this comment with respect to the second bullet point of
          this comment, as it does not appear that you have provided the
          requested disclosure

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


Description of Share Capital, page 114

Differences in Corporate Law, page 118
- --------------------------------------

     4.   We read your response to comment 59 of our letter dated June 28, 2006
          and the revised disclosure in the second sentence of the first
          paragraph. Please delete the term "certain," as it implies that you
          have not discussed all of the material differences between Bermuda and
          Delaware corporate law.


               The disclosure on page 124 has been revised in response to the
          Staff's comment.


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. For example, on page 40, the first column
          heading is adjusted and the second column heading is as further
          adjusted. In your pro forma financial statements, the first pro forma
          column heading is pro forma and the second pro forma column heading is
          pro forma, as adjusted. 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. Also, the related text and footnotes have been
          updated to clarify the definitions of "pro forma" and "pro forma, as
          adjusted".


Note 1. Adjustments to Pro Forma Consolidated Statements of Operations and
Balance Sheet, page F-6
- ---------------------------------------------------------------------------

     6.   Please break out adjustment (A) into two separate adjustments:
          reductions in interest expense due to extinguishments of existing debt
          and additions to interest expense due to new debt. Each of these pro
          forma adjustments should show precisely how the amount of each
          adjustment was computed. Each adjustment should disclose the amount of
          each loan being repaid or issued



Aircastle Limited

          multiplied times its interest rate and arrive at the amount of
          interest expense to be deducted or added in the pro forma adjustment.
          For debt that incurs interest at a variable rate, you should use the
          average variable rate that this debt would have incurred over the
          appropriate historical period for which you are giving pro forma
          effect. Please also disclose the average interest rate used for each
          period and the indexed rate (LIBOR+x% or prime +x%). Make the
          appropriate revisions.


               The disclosure on page F-6 has been revised in response to the
          Staff's comment.

     7.   Please disclose in the footnote to adjustment (B) how you computed the
          amount of the adjustment to your income taxes, including your assumed
          tax rate.


               The disclosure on page F-6 has been revised in response to the
          Staff's comment.

     8.   Please disclose in the footnote to adjustment (J) how you computed the
          amount of the adjustment to your additional paid-in capital.


               The disclosure on page F-8 has been revised in response to the
          Staff's comment.

          contingent rentals related to its floating rate leases
