AAIB publishes Annual Safety Review 2024
We have published our Annual Safety Review which provides an overview of our activity during 2024 including investigations opened, reports published and the safety recommendations made, together with the safety action taken or planned in response to investigations concluded in 2024.
In this year’s Annual Safety Review we also take a closer look at the categorisation of accidents and incidents and the themes that emerged during 2024 in passenger transport events, general aviation fatal accidents and UAS events.
