According to Article 24(1) of Directive (EU) 2016/798, accident and incident reports shall follow as closely as possible the structure here established, adapted to the type and seriousness of the accident or incident. This includes input, in principle, to all titles 1 to 6 including their subtitles in letters, where relevant. Where no relevant information is available or not required due to the circumstances of the occurrence, the statement ‘not applicable’ shall be introduced for the corresponding titles or subtitles, identifying them as not being considered relevant in the context of this investigation. The statement can be done in an aggregated manner either at the beginning or at the end of the relevant title or subtitle.
