engine and required tooling.

2.4    ENGINE MAINTENANCE MANAGEMENT
Planning documents, tailored for individual operators, are developed to serve as
Engine Maintenance Management Program criteria and should reflect the FAA
requirements under which Spirit will operate. These are directed toward the
objective of ensuring cost-effective operation with acceptable post-repair test
performance, providing engine reliability to achieve maximum time between shop
visits, and minimizing the adverse effects to operation of inflight shutdowns
and delays/cancellations. Through the institution of specific maintenance
recommendations, proper engine performance, durability, and hot section parts
lives can be achieved.
2.4.1    Operations Monitoring:
The following information is available to Spirit from the IAE Product
Information Process (IP) 2 Group:
2.4.2    Operation Experience Reports:
IAE maintains V2500 Service Data System (SDS) data base from which selected
engine operations and reliability summary reports will be developed and made
available on a scheduled basis to Spirit. Data reported by IAE Customer Support
Representatives serve as input to this data base. This computerized data
maintenance and retrieval system will permit:
•
A pooling and exchange of service experience for the benefit of the entire
airline industry.

•
A common statistical base.

•
The selective querying of computer data files for answers to Spirit’s inquiries.

In addition to providing operations, reliability and VIS reports, SDS serves
in-house programs directed at improving engine design and enhancing overall
customer support, including spare parts provisioning and warranty
administration.
2.5    SPECIAL PROGRAMS
2.5.1    Engine Hardware Retrofit:
Engine Retrofits are carried out to provide modification of engine hardware
configuration when required on delivered engines. This involves assisting in the
marshaling of hardware, special tools, manpower and the scheduling of engine and
material to modification sites.
2.5.2    Controlled Service Use Programs and Material:
IAE shall assume responsibility for the planning, sourcing, scheduling and
delivery of Controlled Service Use material, warranty replacement material,
service campaign material and program support material subject to the terms of
special contracts with Spirit.

5.0.    SPARE PARTS
5.1    SPARE PARTS SUPPORT
The Spare Parts Group provides the following categories of spare parts support
to Spirit, as requested by Spirit:
•
-    Individual Customer Account Representatives

•
-    Provisioning

•
-    Planning

•
-    Order Administration

•
-    Spare Parts Inventory

•
-    Effective Expedite Service

•
-    Worldwide Distribution

5.1.1    Account Representative:
An Account Representative shall be assigned to Spirit. This representative
provides individualized attention for effective spare parts order
administration, and is the customer's interface on all matters pertaining to new
part planning and procurement. Each representative is responsible for monitoring
Spirit’s requirements and providing effective administrative support. The
Account Representatives shall be thoroughly familiar with Spirit’s spare parts
ordering policies and procedures and are responsible for ensuring that all of
Spirit’s new parts orders are processed in an effective manner.
5.1.2    Spare Parts Provisioning Planning:
Prior to delivery of the first Spirit aircraft, preplanning discussions will be
held to determine the aircraft/engine program, and engine spare parts
provisioning and order plans. Mutually agreed upon provisioning target dates are
then established and on-time completion tracked by Spirit’s Account
Representative with the assistance of logistics specialists in Spare Parts
Provisioning and Inventory Management. Meetings are held with Spirit at a
mutually agreeable time to review suggested spare parts provisioning lists
prepared by Spare Parts Provisioning. These lists are designed to support
Spirit’s particular fleet size, route structure and maintenance and overhaul
program.

*****Confidential portions of the material have been omitted and filed
separately with the Securities and Exchange Commission.

--------------------------------------------------------------------------------

Exhibit 10.3

5.1.3    Order Administration:
IAE subscribes to the general principles of Air Transport Association of America
(ATA) Specification No. 2000, Integrated Data Processing - Supply. The
procedures of Air Transport Association of America (ATA) Specification No. 200
may be used for Initial Provisioning (Chapter II), Order Administration (either
Chapter III or Chapter VI), or Invoicing (Chapter IV).
A spare parts supply objective is to maintain a 90 percent on-time shipment
performance record to Spirit’s requirements. The lead time for replenishment
spare parts is identified in the IAE spare Parts Price Catalog. Initial
provisioning spare parts orders should be placed at least six months prior to
required delivery, while conversions and major modifications require full
manufacturing lead times.
The action to be taken on emergency requests will be answered as follows:
•
Aircraft-On-Ground (AOG) - within four hours (in these instances every effort is
made to ship immediately).

•
Critical (Imminent Aircraft-On-Ground (AOG) or Work Stoppage) -- Within 24
hours.

•
Stock Outage -- Within seven working days (these items are shipped as per
Spirit’s request).

5.1.4    Spare Parts Inventory:
To ensure availability of spare parts in accordance with published lead time,
spare parts provisioning maintains a modern, comprehensive requirements planning
and inventory management system which is responsive to changes in Spirit’s
demand, special support programs and engineering design. Organized on an engine
model basis, this system is intended to maintain part availability for delivery
to customers consistent with published lead times.
A majority of parts in the spare parts inventory are continually controlled by
an Automatic Forecasting and Ordering System. Those parts which do not lend
themselves to automatic control due to supercedure, unusual usage or conversion
requirements are under the direct manual control of Spares Planning personnel.
As additional protection against changes in production lead time or unpredicted
demand, certain raw materials are also inventoried. Successful inventory
management is keyed to accurate requirements planning. In support of the
requirements planning effort, a wide ranging data retrieval and analysis program
is offered. This program concerns itself both with the customer logistics and
technical considerations as follows:
•
Forecasts of life limited parts requirements are requested and received
semi-annually from major customers. Based on the size of Spirit’s order, Spirit
shall be considered a major customer.

•
Engine technical conferences are held frequently within IAE to assess the impact
of technical problems on parts.

•
For a selected group of parts a provisioning conference system is offered which
considers actual part inventory change, including usage and receipts, as
reported monthly by participating customers.
