Annex 13

ANNEX 13 to the Convention on International Civil Aviation

Attached is the 2012/ 2013 latest annex changes:

icao – Annex 2013

Aircraft Accident and Incident Investigation
The causes of an aircraft accident or serious incident must be identified in order to prevent repeated occurrences. The identification of causal factors is best accomplished through a properly conducted investigation. To emphasise this point, Annex 13 states that the objective of the investigation of an accident or incident is prevention.

Annex 13 provides the international requirements for the investigation of aircraft accidents and incidents. It has been written in a way that can be understood by all participants in an investigation. As such, it serves as a reference document for people around the world who may be called on, often without any lead time, to deal with the many aspects involved in the investigation of an aircraft accident or serious incident. As an example, the Annex spells out which States may participate in an investigation, such as the States of Occurrence, Registry, Operator, Design and Manufacture. It also defines the rights and responsibilities of such States.

The ninth edition of Annex 13 consists of eight chapters, an appendix and four attachments. The first three chapters cover definitions, applicability and general information. Chapter 3 includes the protection of evidence and the responsibility of the State of Occurrence for the custody and removal of the aircraft. It also defines how that State must handle requests for participation in the investigation from other States.

All States that may be involved in an investigation must be promptly notified of the occurrence. Procedures for this notification process are contained in Chapter 4. The same chapter outlines the responsibilities for conducting an investigation depending on the location of the occurrence, eg. in the territory of an ICAO Contracting State, in the territory of a non-contracting State, or outside the territory of any ICAO State. Following the formal notification of the investigation to the appropriate authorities, Chapter 5 addresses the investigation process.
Responsibility for an investigation belongs to the State in which the accident or incident occurred. That State usually conducts the investigation, but it may delegate all or part of the investigation to another State. If the occurrence takes place outside the territory of any State, the State of Registry has the responsibility to conduct the investigation.

States of Registry, Operator, Design and Manufacture who participate in an investigation are entitled to appoint an accredited representative to take part in the investigation. Advisers may also be appointed to assist accredited representatives. The State conducting the investigation may call on the best technical expertise available from any source to assist with the investigation.

The investigation process includes the gathering, recording and analysis of all relevant information; the determination of the causes; formulating appropriate safety recommendations and the completion of the final report.

Chapter 5 also includes provisions regarding: the investigator-in-charge, flight recorders, autopsy examinations, coordination with judicial authorities, informing aviation security authorities, disclosure of records, and re-opening of an investigation. States whose citizens have suffered fatalities in an accident are also entitled to appoint an expert to participate in the investigation.

Chapter 6 contains the Standards and recommended practices dealing with the development and publication of the final report of an investigation. The recommended format for the final report is contained in an Appendix to the Annex.

Computerized databases greatly facilitate the storing and analysing of information on accidents and incidents. The sharing of such safety information is regarded as vital to accident prevention. ICAO operates a computerized database known as the Accident/Incident Data Reporting (ADREP) system, which facilitates the exchange of safety information among Contracting States. Chapter 7 of Annex 13 addresses the reporting requirements of the ADREP system which is by means of Preliminary and Accident/Incident Data Reports.

Chapter 8 of Annex 13 deals with accident prevention measures. The provisions in this chapter cover incident reporting systems, both mandatory and voluntary, and the necessity for a non-punitive environment for the voluntary reporting of safety hazards. This chapter then addresses database systems and a means to analyse the safety data contained in such databases in order to determine any preventive actions required. Finally, it recommends that States promote the establishment of safety information sharing networks to facilitate the free exchange of information on actual and potential safety deficiencies. The processes outlined in this chapter form part of a safety management system aimed at reducing the number of accidents and serious incidents worldwide.
