On October 4, 2017, American Airlines, Inc. (the “Company” or “American”) and Wilmington Trust Company, as trustee under certain pass through trusts formed by the Company (the “Trustee”) and as subordination agent, entered into an Amended and Restated Note Purchase Agreement (the “Note Purchase Agreement”), and American, the Trustee and Wilmington Trust Company, as subordination agent, loan trustee and in its individual capacity, entered into amendments to participation agreements (the “Participation Agreement Amendments”) with respect to each Aircraft (as defined below). The Note Purchase Agreement and Participation Agreement Amendments, subject to certain terms and conditions, provided for the issuance on October 4, 2017 by American of Series B equipment notes (the “Equipment Notes”) in the aggregate principal amount of $193,440,000 to be secured by (a) five Airbus A321-200S aircraft delivered new to American from November 2016 to February 2017, (b) eight Boeing 737-800 aircraft delivered new to American from March 2016 to December 2016, (c) four Boeing 787-9 aircraft delivered new to American from October 2016 to January 2017 and (d) eight Embraer ERJ 175 LR aircraft delivered new to American from September 2016 to December 2016 (each, an “Aircraft” and, collectively, the “Aircraft”).

Pursuant to the Note Purchase Agreement, on October 4, 2017, the Trustee entered into the Participation Agreement Amendments substantially in the form of the form of First Amendment to Participation Agreement attached as an exhibit to the Note Purchase Agreement and purchased the Equipment Notes issued under an indenture and security agreement with respect to each Aircraft, as amended by an amendment thereto, substantially in the form of the form of First Amendment to Indenture and Security Agreement attached as an exhibit to the Note Purchase Agreement (each, an “Indenture” and collectively, the “Indentures”) entered into by American and Wilmington Trust Company, as loan trustee, with respect to each Aircraft.

Equipment Notes were issued under each Indenture in one series: Series B, bearing interest at the rate of 3.75% per annum, in the aggregate principal amount equal to $193,440,000. Two other series of equipment notes were previously issued under the Indenture: Series AA, bearing interest at the rate of 3.00% per annum, in the aggregate principal amount equal to $557,654,000 and Series A, bearing interest at the rate of 3.25% per annum, in the aggregate principal amount equal to $256,143,000. The Equipment Notes were purchased by the Trustee using the proceeds from the sale of American Airlines Pass Through Certificates, Series 2016-3B (the “Certificates”).

The interest on the Equipment Notes is payable semiannually on April 15 and October 15 of each year, commencing on April 15, 2018. The principal payments on the Equipment Notes are scheduled for payment on April 15 and October 15 of each year, commencing on April 15, 2018. Final payments with respect to the Equipment Notes are due on October 15, 2025. Maturity of the Equipment Notes may be accelerated upon the occurrence of certain events of default, including failure by American (in some cases after notice or the expiration of a grace period, or both) to make payments under the Indenture when due or to comply with certain covenants, as well as certain bankruptcy events involving American. The Equipment Notes issued with respect to each Aircraft are secured by a lien on such Aircraft and are cross-collateralized by the other Aircraft financed pursuant to the Note Purchase Agreement.

The Certificates were registered for offer and sale pursuant to the Securities Act of 1933, as amended (the “Securities Act”), under American’s shelf registration statement on Form S-3 (File No. 333-216167-01), (the “Registration Statement”). The Certificates were sold pursuant to the Underwriting Agreement, dated as of September 20, 2017, between Credit Suisse Securities (USA) LLC and American. The foregoing description of the Note Purchase Agreement and the other agreements and instruments is qualified in its entirety by reference to such agreements and instruments, copies of which are filed herewith as exhibits and are incorporated by reference herein. For a more detailed description of such agreements and instruments entered into by American with respect to the Certificates, see the disclosure under the captions “Description of the Certificates,” “Description of the Liquidity Facilities,” “Description of the Intercreditor Agreement,” “Description of the Equipment Notes” and “Underwriting” contained in American’s final Prospectus Supplement, dated as of September 20, 2017 (the “Prospectus Supplement”), to the Prospectus, dated as of February 22, 2017, filed with the Securities and Exchange Commission on September 22, 2017 pursuant to Rule 424(b) under the Securities Act, which disclosure is hereby incorporated herein by reference and is qualified in its entirety by reference to the relevant exhibit filed herewith.
