Elements and Performance Criteria

1. Prepare piston engine for test run
   • Documentation is checked to ensure that engine is ready for testing
   • Engine is installed in test rig or test cell, including connection of fuel, oil and electrical supplies and instrumentation
   • Sump or external oil tank is filled with correct grade and type of lubricating oil
   • Test rig/cell fuel tank is filled with correct type and grade of fuel
   • Correct propeller or club is fitted to the engine
   • Test rig/cell is prepared for operation
2. Run and test piston engine performance
   • Engine is started and operating parameters are checked in accordance with maintenance manual and standard enterprise procedures
   • Engine performance is tested and adjusted, where applicable, in accordance with maintenance manual requirements and standard enterprise procedures
   • Engine operating parameters and test results are recorded in accordance with standard enterprise procedures
3. Troubleshoot piston engine faults
   • Available information from maintenance records and test results is used, where necessary, to assist in fault determination
   • Logical processes are used to ensure efficient and accurate troubleshooting
   • Specialist advice is obtained, where required, to assist with, or confirm, the fault and rectification requirement
   • Piston engine component faults are located and the causes of the faults are clearly identified
   • Fault rectification requirements are determined to assist in determining if the engine must be returned to the workshop
4. Remove engine from test rig/cell
   • Engine is removed from test rig/stand in accordance with maintenance manual requirements and standard enterprise procedures
   • Serviceable engines are configured, inhibited and prepared, in accordance with maintenance manual requirements and standard enterprise procedures, for transport or storage
   • Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures
   • Unserviceable engines are returned to workshop in accordance with standard enterprise procedures for rectification or re-work

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to apply hand skills and piston engine theory knowledge and use maintenance publications to test run adjust and troubleshoot the operation of repaired or overhauled engines while applying all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The underlying skills inherent in this unit should be transferable across a range of repair andor overhaul applications associated with piston engines It is essential that the maintenance procedures including the use of correct fuels and lubricants are interpreted and applied to ensure quality and safety standards are achieved Evidence of transferability of skills and knowledge related to engine test running is essential This may be demonstrated through application across a number of engine test runs Capability to interpret test procedures and specifications allowable limits and apply them in practice is critical The application of testing procedures should also clearly indicate knowledge of system operation Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot engine faults before undertaking any action The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved under routine supervision on a representative range of engine test runs This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide
Context of and specific resources for assessment	Competency should be assessed in the work environment or simulated work environment in an applicable engine test rig or test cell It is also expected that general purpose tools and test equipment found in most routine situations would be used where appropriate
