scope:

This directive establishes the Goddard Space Flight Center (GSFC) procedures for investigating mishaps, incidents, and close calls, including the establishment of investigation boards and the development, implementation, and evaluation of corrective actions and lessons learned. This directive is the GSFC implementation of the investigational aspects of NPR 8621.1.

APPLICABILITY. This directive applies to Type B mishaps, Type C mishaps, incidents, and close calls, and to Type A mishaps that have been delegated by NASA Headquarters to GSFC for investigation. This directive applies to all elements of GSFC, to its contractors to the extent specified in their contracts, and to other organizations as specified in written operating agreements. This directive does not apply to mission failures in the Balloon Program Office or Sounding Rocket Program Office in which there is no death, injury, or illness, or unanticipated property damage (see NPR 8621.1). This directive does not apply to investigations concerning civil, criminal, or administrative culpability or legal liability. The safety investigative process shall not be used to direct or justify disciplinary action.

Hazards, as described in NPD 8621.1, are processed in the same manner as close calls, and are not discussed separately.
