In August I997, Tom Hauteur finally called for submissions from the parties to the investigation of Flight 427. Apart from helping with the fact-finding phase of a crash probe, parties are given the opportunity to offer their analyses of those facts and suggest likely causes (or “probable causes,” as the NTSB phrases it). Hauteur’s call for submissions was unusual, however, because the fact-finding part of the probe continued. The Systems, Human Factors, and Operations groups were still at work. Not surprisingly, Hauteur’s request led many observers to assume that one of the longest-running crash investigations in the NTSB’s history was finally winding up, with a finding expected within months, if not weeks. They could not have been more wrong.
