When the Board is notified of a major accident, it launches a “Go Team,” which varies in size depending on the severity of the accident and the complexity of the issues involved. The team may consist of experts in as many as 14 different specialties, coordinated by the investigator-in-charge. Each expert manages a group of other specialists from government agencies and industry in collecting the facts and determining the conditions and circumstances surrounding the accident. The investigative groups formed vary, depending on the nature of the accident, and may look into areas such as structures, systems, powerplants, human performance, fire and explosion, meteorology, radar data, event recorders, and witness statements, among others. After an investigation is completed, a detailed narrative report is prepared that analyzes the investigative record and identifies the probable cause of the accident.
