Elements and Performance Criteria

1. Conduct pre-operational checks on defueller vehicle and auxillary equipment
   • Personal protective equipment is selected and used in accordance with workplace procedures
   • Hazards are identified, risks are assessed and hazard management is implemented
   • Reason for defuelling and quantity of fuel to be defuelled is confirmed
   • Type of aircraft and requirement for overwing or underwing operation is confirmed
   • Pre-operational checks on vehicle and auxiliary equipment are made
   • Ullage in defuelling vehicle or auxillary equipment is checked
2. Position defueller vehicle
   • Defuelling vehicle is moved airside or landside to aircraft
   • Aircraft is approached after checks are made to confirm aircraft engines have stopped and aircraft wheel chocks are in place
   • Vehicle is positioned either underwing or standoff, depending on aircraft type
   • Appropriate precautions are taken to avoid risk of collision with aircraft control surfaces, aircraft engines and other vehicles
   • Defueller vehicle is parked in a position that provides easiest route for evacuation in an emergency
3. Conduct quality checks on product
   • Required documentation is obtained from airline engineer/representative
   • Sample of product on board aircraft is obtained and visual quality checks are made in accordance with workplace procedures
   • Defuelling operations are initiated in response to satisfactory fuel quality checks
   • Defuelling operations are initiated into contingency storage areas for further processing in response to unsatisfactory fuel quality checks
4. Defuel aircraft
   • Vehicle is grounded and bonding lead is connected to aircraft
   • Defuelling safety precautions are implemented prior to commencement of operations
   • Defuelling operations are commenced either using auxiliary power unit (APU) or ground power unit (GPU)
   • Quantity defuelled on completion is verified in accordance with workplace procedures
5. Complete post-defuelling operations
   • Hoses are disconnected, retracted and stowed
   • Fuel confirmed as acceptable for return to storage is discharged into designated segregated storage tank or retained in fueller for ongoing supply operations
   • Fuel identified as contaminated is disposed of in accordance with workplace procedures and regulatory requirements
   • Fueller used to transfer contaminated fuel is de-contaminated
6. Complete documentation
   • Hard copy documentation and paperwork is completed as required and airline representative’s signature is obtained
   • Electronic fuel management systems are used to report, record and verify refuel operations
