| description abstract | Description of Driving Event: On November 21, 1989 two shuttle orbiter tires skidded sufficiently to cause blowouts following the application of brakes during a ground test at Wright Patterson Air Force Base. The skidding was caused by the brakes locking due to the failure of the anti-skid system. This failure was due to the use of non-flight switching valves as part of the test stand. Additional damage occurred to a hydraulic hose and quick disconnect fitting. An investigation also discovered an error in the abort software and the addition of excessively restrictive non-flight orifices in the brake hydralic lines. All of these findings contributed to the failure. | |
