Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate from continuing operations for the first nine months of 2012 was 21.2%. In 2011, the Company's effective tax rate from continuing operations was 25.1% in the first nine months of the year and 21.7% for the full year. The effective tax rate for the first nine months 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 a number of multi-year Pioneer tax status certificates (the "certificates") 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. The certificates are subject to the Company meeting certain capital expenditure and workforce commitments. The first certificate expired in September of 2012, the next certificate is scheduled to expire in the first quarter of 2013 and the remaining certificates are scheduled to expire in the subsequent two years, unless extensions are granted.
