In 2012, the agency tested some of the material properties of the remnants from the OCO and Glory missions, finding that results failed to match certifications previously provided by SPI. At around the same time, the agency found that the original test results for the extrusions were altered in two major ways. First, at the behest of a plant manager, SPI employees made handwritten alterations to more than 2,000 test results between 1996 and 2006, flipping failing grades into passing ones (which were then typed onto certifications sent to more than 200 customers). Second, from around 2002 to 2015, a lab supervisor had employees alter more than 4,100 test results for more than 250 customers, and instructed employees to violate testing standards as well. The agency moved in September 2015 to suspend SPI (now Hydro Extruded Solutions, Inc.) from government contracting.
