There has been growing emphasis on quality measures and process analysis techniques that may be implemented in the daily practice of aviation refuelling to improve the overall quality of safety care. The quality assessment and process controls are most effective when used to determine the level of execution proficiency against the standard of aviation fuel quality control and handling. In this article, we have developed the quality assessment tools, control charts and new key indicator to prioritize the quality improvement that should be actionable and specific to guide process improvement efforts successively. Changing from a regular visual check to an automatic visual inspection tool, as well as from a pass/fail criteria to a satisfaction scale from 1 to 10 in the control, produces systematic data. Control charts are an effective way to separate a change in the process, so the user can focus on issues that are more likely to improve quality and safety. Our proposed quality assessment tools, process control and quality improvement prioritization were used to provide continuous feedback on the aviation refuelling service’s capability to exceed the standards.
