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 while observing relevant work health and safety (WHS) procedures, including the use of material safety data sheets (MSDS) and personal protective equipment (PPE)
   • 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 while observing relevant WHS procedures, including the use of MSDS and PPE
   • 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 while observing relevant WHS procedures, including the use of MSDS and PPE
   • 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

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and include:

applying relevant WHS procedures, including the use of MSDS and items of PPE

using relevant maintenance manuals and standard enterprise procedures to:

prepare engines for test running

install engines in test rigs or test cells

selecting and installing the correct propeller or test club

test run and adjust engine parameters, where applicable

troubleshoot faults identified during the test run

record engine operating parameters

remove engines from the test rig or test cell

complete documentation

configuring and inhibiting serviceable engines for transport or storage.

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 shall 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.
