	us-gaap	Loss Contingency Allegations LossContingencyAllegations	Contractual Terms Clarification. On July 6, 2018, Spirit filed a complaint in Washington Superior Court captioned Spirit AeroSystems, Inc. v. The Boeing Company (No. 18-2-16649-7 SEA). Spirit is seeking payment of money that Boeing owes Spirit for product ordered by Boeing and delivered by Spirit. As of the date of filing the complaint, Boeing has underpaid Spirit approximately $64.0. Boeing claims to be withholding money due to customer warranty claims, which are technical in nature and largely relate to designs that predate Spirit’s separation from Boeing in 2005. Spirit disputes its liability for those claims. Spirit is also asking the court to clarify the parties’ contractual obligations, including that Boeing has no right under the parties’ contracts to withhold money presently due based on disputed warranty claims on past orders. On September 5, 2018, Boeing moved to dismiss three of Spirit’s claims without prejudice and one claim with prejudice. The parties are currently briefing this motion, and the Court has scheduled oral argument for November 16, 2018. Discovery in the case is ongoing.
	us-gaap	Loss Contingency Managements Assessment And Process LossContingencyManagementsAssessmentAndProcess	On October 1, 2018, the Company received notice of a claim related to factory disruptions. Claims are inherently uncertain as they typically include many unsubstantiated items and factual disputes. As such, the Company does not believe it is possible to develop an estimate of reasonably possible loss for this matter. The Company has requested further information and supporting documentation and will continue to re-evaluate the claim. The Company usually resolves claims received in the ordinary course of business in the context of its broad, long-term relationships.

The results of these estimates form the basis for making judgments that may affect the reported amounts of assets and liabilities, including the impacts of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period.</font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management may make significant judgments when assessing estimated amounts of variable consideration and related constraints, the number of options likely to be exercised, and the standalone selling prices of the Company’s products and services. The Company also estimates the cost of satisfying the performance obligations in its contracts and options that may extend over many years. Cost estimates reflect currently available information and the impact of any changes to cost estimates, based upon the facts and circumstances, are recorded in the period in which they become known.</font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. The Company’s contracts with customers are typically for products and services to be provided at fixed stated prices but may also include variable consideration. Variable consideration may include, but is not limited to, unpriced contract modifications, cost sharing provisions, incentives and awards, non-warranty claims and assertions, provisions for non-conformance and rights to return, or other payments to, or receipts from, customers and suppliers. The Company estimates the variable consideration using the expected value or the most likely amount based upon the facts and circumstances, available data and trends and the history of resolving variability with specific customers and suppliers. </font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company regularly commences work and incorporates customer-directed changes prior to negotiating pricing terms for engineering work, product modifications, and other statements of work. The Company's contractual terms typically provide for price negotiations after certain customer-directed changes have been accepted by the Company. Prices are estimated until they are contractually agreed upon with the customer. When a contract is modified, the Company evaluates whether additional distinct products and services have been promised and whether allocation of consideration is necessary. If not, the modification is treated as a change to the performance obligations within the existing contract, or otherwise accounted for as a new contract prospectively.</font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company allocates the consideration for a contract to the performance obligations on the basis of their relative standalone selling price. The Company estimates the likelihood of the amount of options that the customer is going to exercise when assessing the existence of performance obligations with respect to this allocation or for assessing the impact of loss contracts.</font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company typically provides warranties on all the Company's products and services. Generally, warranties are not priced separately because customers cannot purchase them independently of the products or services under contract so they do not create performance obligations. Spirit warranties generally provide assurance to the Company's customers that the products or services meet the specifications in the contract. In the event that there is a warranty claim because of a covered design, material or workmanship issue, the Company may be required to redesign or modify the product, offer concessions, and/or pay the customer for repairs or perform the repair. Provisions for estimated expenses related to design, service, and product warranties and certain extraordinary rework are made at the time products are sold. These costs are accrued at the time of the sale and are recorded as unallocated cost of sales. These estimates are established using historical information on the nature, frequency, and the cost experience of warranty claims, including the experience of industry peers. In the case of new development products or new customers, Spirit also considers factors including the warranty experience of other entities in the same business, management judgment, and the type and nature of the new product or new customer, among others. </font></div><div style="line-height:174%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Actual results could differ from those estimates and assumptions.</font></div></div>
