Department of War · 9/10/96 · Document

DOW-UAP-D48, Department of the Air Force Report, 1996 is indexed as a Department of War record with incident date 9/10/96. This report describes the Modeling of Unlikely Space-Booster Failures in Risk Calculations, documenting historical launch failure modes and recommending corrective actions to address them using novel modelling techniques.

Notable / anomalous element

• valve caused vehicle instability and tumbling. (native PDF text, page 135)
• Sustainer began tumbling at booster staging when control was essentially lost. (native PDF text, page 128)
• The vehicle began an accelerated nose-down tumbling motion that subsequently resulted in early and erratic main-engine shutdown due to propellant starvation. (native PDF text, page 139)
• Transtage experienced a guidance anomaly during coast prior to second bum resulting in an improper orbit. (native PDF text, page 171)
