ANNEXU.K.The structure to follow on the reporting

4. Analysis of the occurrence, where necessary in respect of individual contributing factors U.K.

This part of the report shall analyse the established facts and findings (i.e. performance of operators, rolling stock and/or technical installations) which caused the occurrence.

An accident or incident may be caused by causal, systemic and contributing factors which are equally important and should be considered during an investigation.

The analysis may be extended to conditions, feedback mechanisms and/or control mechanisms throughout the entire railway system that were identified as actively influencing the development of similar occurrences. This could comprise the functioning of safety management systems of involved parties and regulatory activities covering certification and supervision.

The following items shall be covered for each of the identified events or factors (causal or contributing) that appear safety critical, in line with the flexibility offered by the structure (see above).
