AMC1 21L.A.3(a) Reporting system ED Decision 2023/013/R COLLECTION, INVESTIGATION AND ANALYSIS OF EVENTS In the context of the following AMC and GM, the term ‘event’ refers to any failure, malfunction, defect, error, near miss, hazard identification, incident, accident or other occurrence that is subject to a reporting system. The ‘collection’, ‘investigation’ and ‘analysis’ functions of the reporting system should include means to: — analyse events and related available information; — identify adverse trends; — investigate the associated root cause(s); and — determine any necessary corrective action(s). It should also allow the determination of reportable occurrences as required under points [21L.A.3](#_DxCrossRefBm1649097723)(a)(3) or [21L.A.3](#_DxCrossRefBm1649097723)(b)(3), as applicable. In addition, for parts whose failure could lead to an unsafe condition, the ‘analysis’ function of the reporting system should ensure that reports and information sent, or available, to the design approval holder or declarant of a declaration of design compliance are fully investigated so that the exact nature of any event and its effect on continuing airworthiness is understood. This may then result in changes to the design and/or to the instructions for continued airworthiness (ICAs), and/or in establishing a mitigation plan to prevent or minimise the possibility of such occurrences in the future, as necessary. The ‘analysis’ is not limited to those occurrences that require the involvement of the Agency under point [21L.A.3](#_DxCrossRefBm1649097723)(e). ##### AMC1 21L.A.3(a) Reporting system *ED Decision 2023/013/R* **COLLECTION, INVESTIGATION AND ANALYSIS OF EVENTS** In the context of the following AMC and GM, the term ‘event’ refers to any failure, malfunction, defect, error, near miss, hazard identification, incident, accident or other occurrence that is subject to a reporting system.
