AMC1 ATM/ANS.OR.A.065(e) Occurrence reporting ED Decision 2022/004/R ORGANISATIONS THAT REPORT TO THE AGENCY (a) Mandatory reports and, where possible, voluntary reports, should include the information below: (1) when: UTC date; (2) where: State/area of occurrence — location of occurrence; (3) aircraft-related information: aircraft identification: State of registry, make–model–series, aircraft category, propulsion type, mass group, aircraft serial number, aircraft registration number, and call sign; (4) aircraft operation and history of flight: operator, type of operation, last departure point, planned destination, flight phase; (5) weather: relevant weather; (6) where relevant, ANS-related information: ATM contribution, service(s) affected, ATS unit name; (7) where relevant, aerodrome-related information: location indicator (ICAO airport code), location at the aerodrome; and (8) information on aircraft damage or on injuries to persons: severity in terms of highest damage and injury level, number of injured persons, and type of injuries to them, on the ground and in the aircraft. (b) Where the organisation identifies an actual or potential aviation safety risk as a result of its analysis of occurrences or a group of occurrences reported to the Agency, it should: (1) transmit the following information to the Agency within 30 days from the date of notification of the occurrence to the Agency: (i) the preliminary results of the risk assessment performed; and (ii) any preliminary mitigation action to be taken; (2) where required, transmit the final results of the risk analysis to the Agency as soon as they are available and, in principle, no later than 3 months from the date of initial notification of the occurrence to the Agency. (c) The following list provides examples of what needs to be mandatorily reported in addition to those required by point [ATM/ANS.OR.A.065](#_DxCrossRefBm647742043)(c). This list should not be understood as being an exhaustive collection of all the issues that may pose a significant risk to aviation safety and, therefore, reporting should not be limited to the items listed therein. 1.
