In principle, it required pilots to complete a "risk assessment form" that assigned numerical scores to various aspects of the proposed operation -- crew, weather, equipment, environment, etc -- and then, on the basis of the total score, provided a cumulative risk factor -- low, caution, moderate, high. A low-risk flight required only the pilot's approval; caution required the pilot to take steps to mitigate the risk; moderate risk required consultation with the company; and so on. Naturally, this type of bureaucratic effort to reduce highly complex, subjective judgments to computer-friendly zeros and ones tends to devolve into an empty and irritating routine, and it seemed to have done so at this operator. The NTSB interviewed a number of pilots, and found no "continuity" among them. Some filled out a risk assessment form daily, some for each flight. The fate of the forms, once completed, was unclear; the main office was unable to produce any completed forms, including the one for the accident flight.
