   • Diagnostic options are analysed and those most appropriate to the circumstances are selected
   • Hazards associated with the work are identified and risks are managed
   • Diagnostic tools and equipment are selected and checked for serviceability
2. Diagnose propeller drive system
   • Diagnostic tests are performed according to workplace procedures and safety requirements
   • Faults are identified from diagnostic test results and causes of faults are determined
   • Diagnosis findings are reported according to workplace procedures, including recommendations for necessary repairs or adjustments
3. Repair propeller drive system
   • Repair information is sourced and interpreted
   • Repair options are analysed and those most appropriate to the circumstances are selected
   • Repair tools, equipment and materials are selected and checked
   • Repairs and component replacements and adjustments are carried out according to manufacturer specifications, workplace procedures and safety requirements, and without causing damage to components or systems
