Revenue Recognition [Abstract]
Milestone Revenue Recogntion [Text Block]	8. Research and Development Milestones Milestone payments. Milestone payments are recognized as revenue when milestones are deemed to be substantive and are achieved. A substantive milestone is one that is based on successful performance by the Company and not solely contingent upon the passage of time or performance by another party. Milestone payments collected in advance that have significant future performance obligations are presented as advance payments or deferred revenue, and are recognized when the milestone is achieved. As part of our ongoing participation in the B787-9 program, we received research and development milestone payments of $4.6 and $2.8 for the three months ended March 28, 2013 and March 29, 2012, respectively. Revenue and cost associated with the performance of this research and development are included in program revenue and costs. We expect to receive additional payments related to research and development on this program. These additional payments remain un-negotiated as of March 28, 2013.

Milestone Revenue Recogntion [Text Block]

8. Research and Development Milestones

Milestone payments. Milestone payments are recognized as revenue when milestones are deemed to be substantive and are achieved. A substantive milestone is one that is based on successful performance by the Company and not solely contingent upon the passage of time or performance by another party. Milestone payments collected in advance that have significant future performance obligations are presented as advance payments or deferred revenue, and are recognized when the milestone is achieved.

As part of our ongoing participation in the B787-9 program, we received research and development milestone payments of $4.6 and $2.8 for the three months ended March 28, 2013 and March 29, 2012, respectively. Revenue and cost associated with the performance of this research and development are included in program revenue and costs. We expect to receive additional payments related to research and development on this program. These additional payments remain un-negotiated as of March 28, 2013.
