Abstract This paper examines Line Operations Safety Audit (LOSA), and explores the feasibility as well as implications of adapting it from a multi-crew setting to single-pilot operations. LOSA is designed to provide a proactive snapshot of system safety and flight crew performance as a way of preventing incidents and accidents (Klinect, 2006). The data indicators underlying this effort are based on a conceptual framework known as Threat and Error Management (TEM) (Helmreich et al, 2001). Incidents and accidents involving single pilot operations have increased in New Zealand over the past decade. Statistics show that this category has a higher incidence of accidents and incidents than in other sectors of the industry (CAA , 2006). By adapting LOSA to single pilot operations (LOSA:SP) the framework/methodology could provide a proactive method of diagnosing operational safety performance strengths and weaknesses leading to the identification of additional training requirements without relying on adverse safety events for such information.
