Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate from continuing operations for the first half of 2012 was 22.2%. In 2011, the Company's effective tax rate from continuing operations was 25.7% in the first half of the year and 21.7% for the full year. The effective tax rate for the first half of 2011 included the recognition of $1,793 of discrete tax expense related to tax adjustments for earlier years. The decrease in the 2012 effective tax rate from continuing operations was driven primarily by the absence of this discrete item and the impact of a decrease in the planned repatriation of a portion of current year foreign earnings to the U.S., partially offset by a projected change in the mix of earnings attributable to higher-taxing jurisdictions or jurisdictions where losses cannot be benefited in 2012. The Company was awarded multi-year Pioneer tax status by the Ministry of Trade and Industry in Singapore for the production of certain engine components by the Aerospace aftermarket business, the earliest of which was granted in August 2005 retroactive to October 2003. In 2010, the Pioneer tax status for certain of the Company's engine components was awarded a two-year extension in exchange for capital investment commitments. The Pioneer tax status is generally awarded for periods of seven to nine years from the effective date and the first two Pioneer certificates are scheduled to expire in the second half of 2012 and the first quarter of 2013, respectively.
