Effective safety managemen<sup>t</sup> has always been a key objective for the broader airworthiness sector. This Special Issue is focused on safety themes with implications on airworthiness management. It o ffers a diverse set of analyses on aircraft maintenance accidents [1–4], empirical and systematic investigations on important continuing airworthiness matters [5–7] and research studies on methodologies for risk and safety assessment in continuing and initial airworthiness [8–10]. Overall, this collection of papers is a valuable addition to the published literature, and I am confident that the readers of Aerospace will find that useful.
