Nonconforming Titanium Task Force Actions to Resolve Aircraft Safety Issues due to Improperly Substituted Material.

摘要

Titanium material used in aerospace applications was found to be nonconforming to various military, industry, and professional society material specifications due to a common industry practice of cutting (versus rolling) billet material and certifying it as meeting bar or rolled plate specifications. A USAF task force was assembled to address the potential safety and readiness impacts to USAF aircraft and to coordinate findings and recommendations with other Services and Agencies investigating impacts to aircraft and other products. This report summarizes the work undertaken by the nonconforming titanium task force from August 2009 to December 2011.
