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:
