New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Description	Valuation reserves for excess, obsolete, and slow-moving inventory are estimated by comparing the inventory levels of individual parts to both future sales forecasts or production requirements and historical usage rates in order to identify inventory where the resale value or replacement value is less than inventoriable cost. Other factors that management considers in determining the adequacy of these reserves include whether individual inventory parts meet current specifications and cannot be substituted for a part currently being sold or used as a service part, overall market conditions, and other inventory management initiatives. Manufacturing costs are allocated to current production and firm contracts. Under prior accounting within commercial aerospace, the unit of accounting for certain contracts was the contract, and early-contract OEM unit costs in excess of the average unit costs expected over the contract were capitalized and amortized over lower-cost units later in the contract. As described in the "Revenue Recognition" section of Note 1 below, these costs were eliminated through retained earnings on January 1, 2018 and will not be amortized into future earnings based on the adoption of Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers.

New Accounting Pronouncement or Change in Accounting Principle, Description	In February 2016, In February 2016, the FASB issued ASU 2016- 02, Leases (Topic 842). In 2018, the FASB continued to issue various updates to ASU 2016-02 as follows: ASU 2018-10, Codification Improvements to Topic 842, Leases - makes various targeted enhancements and clarifications to the leasing standard ASU 2018-11, Leases (Topic 842): Targeted Improvements - allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption ASU 2016-02 and its related updates (collectively, the New Lease Accounting Standard) are effective for reporting periods beginning after December 15, 2018, and interim periods therein, using either of the following transition methods; (i) a full retrospective adoption reflecting the application of the standard in each prior reporting period, or (ii) a prospective adoption election with the cumulative effect of adopting recognized through retained earnings at the date of adoption. We are preparing to adopt the New Lease Accounting Standard effective January 1, 2019 and will used the prospective method of adoption with the cumulative effect of adoption recognized through retained earnings at the date of adoption. The New Lease Accounting Standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statement of Operations. In addition, this standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as financing. If the lessor doesn’t convey risks and rewards or control, the lease is treated as operating. We plan to elect all of the practical expedients available under the New Lease Accounting Standard upon adoption. Although we continue to evaluate the impact of the New Lease Accounting Standard on our statement of financial position, we do not expect that the standard will have a material effect on our cash flows or results of operations. Upon adoption we will record a ROU asset and lease liability, representing our obligation to make lease payments for operating leases, measured on a discounted basis. The ROU asset and lease liability will also reflect future payments under certain information technology service contracts, which we have determined contain embedded leases, which require balance sheet presentation under the New Lease Accounting Standard. We expect the ROU asset and lease liability recorded will be less than 5% of our total assets. In preparation for the adoption, we are implementing new software solutions and designing new business processes and controls over the financial reporting of leases, which will facilitate our reporting under the New Lease Accounting Standard in the first quarter of 2019.

New Accounting Pronouncement or Change in Accounting Principle, Description	In August 2018, the SEC issued the final rule under SEC Release No. 33-10532, "Disclosure Update and Simplification," that amends certain of its disclosure requirements that have become redundant, duplicative, overlapping, outdated or superseded.

These disclosures are required to be provided for the current and comparative year-to-date interim periods. The final rule is effective for all filings on or after November 5, 2018.

New Accounting Pronouncement or Change in Accounting Principle, Description	In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities. The amendments in this Update for determining whether a decision-making fee is a variable interest require reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in GAAP). Therefore, these amendments likely will result in more decision makers not having a variable interest through their decision-making arrangements. These amendments also will create alignment between determining whether a decision making fee is a variable interest and determining whether a reporting entity within a related party group is the primary beneficiary of a VIE. If fewer decision-making fees are considered variable interests, the focus on determining which party within a related party group under common control may have a controlling financial interest will be shifted to the variable interest holders in the group with more significant economic interests. This will significantly reduce the risk that decision makers with insignificant direct and indirect interests could be deemed the primary beneficiary of a VIE. The provisions of this ASU are effective for years beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the impact of this ASU.

New Accounting Pronouncement or Change in Accounting Principle, Description	In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. The amendments in this Update make targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements as follows: clarify that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements; add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606; and require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. The provisions of this ASU are effective for years beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the impact of this ASU.
