... In particular, the GAO study (1990) found that all of the NASA centers with the exception of the Jet Propulsion Laboratory were spending between 0.9 and 1.5 percent of their facilities' estimated current replacement values on maintenance and that this was resulting in severe deterioration of the facilities and catastrophic breakdowns such as the rupture of a high-pressure steam shutoff valve at the Lewis Research Center in 1989.
