Webof four solid rocket motor sections mated together using equally spaced pins. The segments are assembled using a series of field joints and factory joints (Figure-l). The field joint differs by incorporating a capture feature with an additional O-ring in the tang. This was developed for safety purposes as a result of the Challenger accident. Webfail.field, fail.nozzle: binary variables indicating whether there was an incident with the O-rings in the field joints or in the nozzles of the solid rocket boosters. 1 codifies an incident and 0 its absence. For the analysis, we focus on the O-rings of the field joint as those were the most determinants for the accident.

Subsequently, the field joint mating pins were lengthened and a retaining band added to improve the shear strength of the pins and increase metal part’s joint margin of safety.
