ICAO Final Report format.

How are accident reports written ? Is there any standard format ?

ICAO Final Report formatICAO Final Report Format.

ICAO states how a Accident Final Report should be written. According to “Annex 13 to the Convention on International Civil Aviation (International Standards And Recommended Practices)” , ICAO defines the guidelines related to Aircraft Accident and Incident Investigations.


In this important and useful document are clearly stated most of the actions a National Civil Aviation organization should follow when notified about an accident or incident : Organization and conduct of the investigation , use of Flight recorders, rules regarding Participation in the investigation (by the State of Registry, the State of the Operator, the State of Design and the State of Manufacture ), Protection of evidence, custody and removal of aircraft, Release of the Preliminary and Final Report, Safety recommendations, the Responsibility of a State receiving safety recommendations.

APPENDIX 1 is the description of Format of the Final Report, which you will find in most of the Aviation Accident reports in this website. Let’s review it togheter :

Title. The Final Report begins with a title comprising: name of the operator; manufacturer, model, nationality and registration marks of the aircraft; place and date of the accident or incident.

Synopsis. Following the title is a synopsis describing briefly all relevant information regarding: notification of accident to national and foreign authorities; identification of the accident investigation authority and accredited representation; organization of the investigation; authority releasing the report and date of publication; and concluding with a brief résumé of the circumstances leading to the accident.

Body. The body of the Final Report comprises the following main headings:
1. Factual information
2. Analysis
3. Conclusions
4. Safety recommendations each heading consisting of a number of subheadings as outlined in the following.

Appendices. Include as appropriate.

Note.— In preparing a Final Report, using this format, ensure that:
a) all information relevant to an understanding of the factual information, analysis and conclusions is included under each appropriate heading;
b) where information in respect of any of the items in 1.— Factual information is not available, or is irrelevant to the circumstances leading to the accident, a note to this effect is included under the appropriate subheadings.

Whenever practicable, the Final Report sent to ICAO is to be prepared in one of the working languages of the Organization (English, Arabic, Chinese, French, Russian and Spanish)

Despite of this clear note, many National Safety Agencies (ANSV Italy, BEA France, Aircraft and Railway Accidents Investigation Commission Japan) are preparing final reports in their own language, by preventing most of the aviators from learning.
With this regrettable behavior they , in practice , jeopardize safety.
