AMC1 DPO.OR.A.045(e) Failures, malfunctions and defects ED Decision 2024/002/R FOLLOW-UP AND CLOSURE OF REPORTED OCCURRENCES (a)       The organisation should transmit the following information to EASA within 30 days from the date of notification of the occurrence to EASA: (1)       the latest position of the organisation responsible for design as to whether an unsafe, insecure or under-performing condition is confirmed; (2)       the results of the occurrence analysis and of the first investigation — including the cause(s) of the occurrence and missing information, if known; and (3)       the measures it has taken, intends to take or proposes to take, including an assessment evaluating whether the product can be operated safely until the corrective action is defined and implemented, or that immediate mitigation measures need to be implemented until a more refined assessment can be provided. (b)       The final (close-out) report, as soon as available and, in principle, no later than 3 months after the occurrence notification, should include: — the final position of the organisation involved in the design as to whether an unsafe, insecure or under-performing condition exists; — the results of the occurrence analysis and of the final investigation — including the cause(s) of the occurrence and missing information; — any corrective and preventive measures taken by the reporting organisation; and — an assessment evaluating whether these corrective and preventive measures allow the product to be operated as intended. (c)       Notwithstanding point (a), when the organisation identifies that no unsafe, insecure or under-performing condition exists as a result of their analysis of a voluntarily reported occurrence, it can delay further communication to EASA up to the issuance of the final report and report the occurrence as closed upon issue (data exchange). In such cases, no follow-up report should be submitted. The final report to EASA should include confirmation and justification that no unsafe, insecure or under-performing condition exists. The organisation is requested to provide information on the cause(s) of the occurrence and on the corrective or preventive measures that were taken by the organisation. This way of reporting should not be understood as an accepted deviation from the applicable requirements. If, at any stage during the investigation, the organisation identifies that a possible unsafe, insecure or under-performing condition exists, it should be communicated to EASA via a mandatory report within 72 hours.
