The Bureau of Aircraft Accidents Archives (B3A) was established in Geneva in 1990 for the purpose to deal with all information related to aviation accidentology. The primary goal of the B3A is to collect, manage and archive all information relating to aviation accidents worldwide since 1918 till today. Therefore, its records is currently composed of thousands of documents, reports, photos, etc. representing to date more than 23’300 events. The second goal of the B3A is to promote aviation safety through know-how action plans, training and information. On request, the B3A can participate in investigations, publish procedures and/or send any recommendations if necessary. The third goal of the B3A is to inform the public and professionals of the risks inherent in the operation of an aircraft and training on psychological preparedness for mass disaster. With an experience of more than 25 years, the B3A now offers its services and expertise in managing situations of mass disasters not only in aviation but in all other transportation modes: boats, trains, automobiles, etc. We should remind we must constantly challenge ourselves and understand that an accident is generally multi-factorial with human factor as the first cause.
