Visual inspection is a fundamental safety critical task in the air transport industry. This study investigates how a visual search strategy with a specific eye scanning pattern can be used to improve the observation of aircraft defects during visual inspection tasks. N=100 aircraft maintenance technicians were recruited and N=48 were allocated to a control condition. This group conducted pre-flight visual inspections on aircraft, using their normal custom and practice. The remaining N=52 experimental group participants were trained to use a specific eye scanning pattern during their pre-flight inspection called systematic visual search. Prior to inspections, the number of observable defects …

This paper investigates human performance on a set of selected tasks in an aviation maintenance organisation, where a significant prevalence of unsafe acts and conditions were observed. The methodology began with visual inspections of the work environment. Semi structured interviews were then undertaken to gain an insight into the job demands and critical issues reported by front line operators. Three representative critical tasks were then selected for a detailed task analysis. This fed into a task based risk assessment that mapped out safety critical deviations together with timelines for nominal and deviation paths. The likelihood and severity of potential outcomes …
