In recent years, several major transportation accidents have brought significant attention to the role organizational factors play in motivating operator safety within high-risk systems, yet very little has been studied regarding the direct contribution organizational factors play in accidents. This study elucidates the types of organizational factors associated with aviation accidents attributed principally to pilot error, through case-based analyses of commercial accidents from 1990 to 2000. Results indicate inadequate procedures and directives rank highest among organizational problems. Findings suggest interventions aimed at organizational contributions may potentially ameliorate a myriad of systemic problems, rather than assigning blame to the pilot at the operational level.
