The objective of the ICAO Accident/Incident Reporting (ADREP) System is to provide states with services that they can employ in their own accident-prevention programs. Six main services are available: Prompt response to the requests of states; reasonable response to requests for federal information; monthly summaries of preliminary accident reports; an annual Digest of Accident statistics; periodical print-outs of states' reports and, ADREP computer programs. States contribute to ADREP by sending reports to ICAO on all accidents to aircraft of over 2,250 kg. States compile these reports using special computer-compatible reporting forms and the related ADREP Manual-Reports received from states are first checked against a "manual" log in which are recorded all accidents that have come to ICAO's attention on the basis of "unofficial information". These are entered into the mini-computer which then checks for previous reports on that accident. After being verified, edited and updated, the monthly batch of reports is then printed by the computer as a Preliminary Report summary. The information stored in the computer is checked four times: first manually, when the report is received, second, by mini-computer during input; third, by the edit-update program; and fourth, the submitting state.
