FOREWORD General -- I. The purpose of the Aircraft Accident Digest is to disseminate accident report information to all Contracting States. Publication of the Digest began in 1951. Over the years, States have reiterated their interest in the Digest, not only as a valuable source of informatlun for accident prevention, but also as a training aid for investi- gators and educational material for technical schools. Selection of accidents 2. The Digest contains accident reports selected by the Secretariat from those sent by States. Reports were selected on the basis of a their contribution to accident prevention or b the successful employment of useful or effective investigative techniques and c compliance with Annex 13 specifications, including the "format of the final report". The Digest should not be seen as being statistically representative of the world distribution of accidents. 3. The Final Reports are usually published as received. Accordingly, some deviations from standard ICAO editorial practice may occur. Lengthy reports may be abbreviated by omitting redundant information or appendices, attachments and diagrams. States' - co-operation 4 . States are encouraged to send to ICAO those Final Reports which meet the criteria of 6.14 in Annex 13. The reports must be submitted in one of the working languages of ICAO, and in the format presented in the Appendix to Annex 13. Digest publication 5. The Digest is produced once each year and includes accidents and incidents which occurred during a one-year period.
