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

Page 34 of 34

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.

Urgent customer shipments, both inbound and outbound, are monitored, traced, routed and expedited as required. The receipt and movement of customer owned material returned to IAE is carefully controlled, thus assuring an accurate accounting at all times.

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

Page 44 of 44



•			- 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.

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:

Page 45 of 45



•			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.

5.1.5 Packaging

All material is packaged in general compliance with Air Transport Association of America (ATA) Specification No. 300.

5.1.6 World Airline Supplier's Guide:

IAE subscribes to the supply objectives set forth in the World Airlines Supplier's Guide published by the Air Transport Association of America (ATA). IAE requires that its proprietary component vendors also perform in compliance with the precepts of the World Airline Suppliers' Guide.
