(n) Section 3.5(b) of the Supplement is hereby amended and restated to read in its entirety as follows:

“(b) The Issuer shall maintain (or shall cause the Servicer to maintain) records that will identify amounts on deposit in the Series 1997-1 Engine Reserve Account to a specific Eligible Engine. The Servicer shall be entitled to withdraw funds from the Series 1997-1 Engine Reserve Account for the payment of maintenance expenses with respect to the related Eligible Engine, at the times and subject to the further conditions set forth in the Servicing Agreement; provided, however, that the Servicer may not make any such withdrawal in an amount greater than $1,000,000 unless the Deal Agent determines (or is deemed to determine) that the use of proceeds of such withdrawal complies with the Maintenance Reserve Withdrawal Conditions (as defined below).

The Servicer shall give the Indenture Trustee and the Deal Agent prior written notice of any such requested withdrawal in excess of $1,000,000, accompanied by supporting documentation showing compliance with the Maintenance Reserve Withdrawal Conditions. Such request shall be accompanied by a notice in the form of Exhibit E to this Supplement, duly completed (a “Withdrawal Notice”). The Indenture Trustee shall, upon receipt of such notice of a requested withdrawal and supporting documentation, transmit copies thereof by telecopy to the Deal Agent. If such notice and documentation are received by the Indenture Trustee prior to 2:00 p.m. (New York time) on any Business Day, the Indenture Trustee will telecopy the same to the Deal Agent at (000) 000-0000 on the same Business Day. In all other cases the Indenture Trustee will telecopy such notice and documentation to the Deal Agent at such telecopy number on the next Business Day following the Indenture Trustee’s receipt thereof. If the Deal Agent determines that such supporting documentation does not show that such drawing complies with the Maintenance Reserve Withdrawal Conditions or that it has received insufficient supporting documentation to show such compliance, it will so indicate by signing the applicable Withdrawal Notice in the space provided, and sending such signed Withdrawal Notice to the Indenture Trustee and the Servicer no later than 5:00 p.m. (New York time) on the second Business Day after the day on which the Deal Agent received such telecopy from the Indenture Trustee. Such notice by the Deal Agent, if given, will be sent to the Indenture Trustee by telecopy at (212) 328–7623. If the Indenture Trustee does not receive such notice by 5:00 p.m. (New York time) on such second Business Day at such telecopy number, the Deal Agent will be deemed to have determined that such withdrawal complies with the Maintenance Reserve Withdrawal Conditions. If the Indenture Trustee timely receives such Withdrawal Notice signed by the Deal Agent, it will not permit the applicable withdrawal from the Series 1997-1 Engine Reserve Account. If the Indenture Trustee does not timely receive such Withdrawal Notice signed by the Deal Agent, it will permit the applicable withdrawal.

The “Maintenance Reserve Withdrawal Conditions” applicable to any Withdrawal Notice are that

(i) the amount requested to be withdrawn must be no greater than the aggregate amount of the invoices for work done on the applicable Eligible Engine, copies of which are delivered as part of the supporting documentation for such Withdrawal Notice, and

(ii) the amount requested to be withdrawn must be no greater than the aggregate amount of all Maintenance Reserve Payments on deposit in the Series 1997-1 Engine Reserve Account which were shown as being allocated to the applicable Eligible Engine in the most recently delivered Servicer Report.

Notwithstanding the foregoing, so long as a Servicer Default is then in effect, the Servicer shall not be entitled to make any such withdrawal (irrespective

of the amount thereof) except upon presentation of supporting documentation reasonably determined by the Deal Agent to comply with the Maintenance Reserve Withdrawal Conditions and the terms of the applicable Lease Agreement (which shall evidence its determination by written instrument delivered to the Indenture Trustee).”

(o) Section 4.6 of the Supplement is hereby amended and restated to read in its entirety as follows:

“Section 4.6 Insurance.
