Release 1. This is the first release of this unit of competency in the AVI Aviation Training Package.

This unit involves the skills and knowledge required to conduct quality control operations related to refuelling and defuelling aircraft in compliance with relevant regulatory requirements of the Civil Aviation Safety Authority (CASA) and national operating standards.

It includes taking samples from dispensers/fuellers, conducting a visual check of fuel samples, testing membrane filtration (millepore sampling) and measuring pressure differential on filter vessels.

This unit addresses aviation technical skill requirements (physical, mental and task-management abilities) related to quality control operations of ground operations personnel and contributes to safe and effective performance in complex aviation operational environments.

Operations are conducted as part of recreational, commercial and military aircraft activities across a variety of operational contexts within the Australian aviation industry.

Work is performed independently or under limited supervision as a single operator or within a team environment.

Licensing, legislative, regulatory or certification requirements are applicable to this unit.
