The main risks to large public transport aeroplanes are identified through analysis of worldwide fatal accidents, which is a task carried out annually in the UK by the CAA Accident Analysis Group (AAG). The output of the AAG forms a key part of the UK CAA Safety Planning process in that these main risks are assessed for their relevance to the UK aviation system and, where appropriate, safety interventions are identified to mitigate them. These safety interventions can be found in the CAA Safety Plan. This document summarises a study of AAG analysed worldwide fatal accidents to jet and turboprop aeroplanes above 5,700 kg engaged in passenger, cargo and ferry/positioning flights for the ten-year period 1997 to 2006.
