Reporting of Acts of Unlawful Interference

The reporting of acts of unlawful interference with civil aviation provides ICAO with data that is critical to evaluating and analyzing security incidents and trends. ICAO Member States are required by Annex 17 to the Chicago Convention to report to ICAO as soon as possible after an incident has been resolved. In accordance with Annex 17, each Contracting State must provide pertinent information on every incident of unlawful or attempted seizure of aircraft or aviation facilities. Through analysis of such occurrences, experts are able to develop effective measures that form the keystone of an aviation security programme.

To facilitate this process, a reporting form can be found in the ICAO Aviation Security Manual (Doc 8973 – Restricted). The form, called Official Report on Act of Unlawful Interference, is available to ICAO Member States in all languages. The form can be downloaded below in all languages.
