COLLECTION, INVESTIGATION, AND ANALYSIS OF EVENTS
In the context of the following AMC and GM to point 21.A.3A, the term âeventâ refers to any failure, malfunction, defect, error, near miss, hazard identification, incident, accident, or other occurrence that is subject to a reporting system.
The âcollectionâ, âinvestigationâ, and âanalysisâ functions of the system should include means:
â to analyse events and related available information;
â to identify adverse trends;
â to investigate the associated root cause(s); and
â to determine any necessary corrective action.
It should also allow the determination of reportable occurrences as required by point 21.A.3A(a)(3) or 21.A.3A(b)(3), as applicable.
In addition, for parts whose failure could lead to an unsafe condition, the âanalysisâ function of the system should ensure that reports and information sent, or available, to the design approval holder (DAH) 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 (ICA), and/or in establishing a mitigation plan to prevent or minimise the possibility of such occurrences in the future, as necessary. The âanalysisâ is not limited to those occurrences that require the involvement of EASA under point 21.A.3A(e).
