This paper findscontributory factors to airspace infringements concerning the planning undertaken bygeneral aviation pilots. Twenty seven recreational pilots who flew a light fixed-wing motor, glider and ultralight aircraft were interviewed using semi-structured interviews in Finland, Norway and United Kingdom. These countries experienced a major problem with the number of reported AIs. Interview transcripts were analysed using thematic analysis. The success of this study is attributed to the carefully design of both the questions of the interview and the sample that comprises the diverse general aviation sector.The newly found contributory factorsare associated with a pilot’s performance as well as airspace design features that can influence the pilot’s flight route decision-making, e.g. wished flying altitude is higher than the lower boundary of controlled airspace in the capital of a country. The findings can aid the incident investigation and the development ofmitigation actions of these incidents.
