(a) Performance Evidence

      Evidence required to express competency in this unit must be related to and fulfil all of the requirements of the elements and performance criteria under the indicated conditions of assessment, and must include: 

•    Applying relevant WHS procedures, including the use of MSDS and PPE.

•    Using relevant maintenance documentation, specifications and aircraft/component manuals to:

•    Recognise state of serviceability and overhaul or repair requirements for piston engine.

•    Crankcase assembly components as listed in the Range of Conditions.

•    Dismantle and inspect crankcase assembly component parts for serviceability and.

•    Identify repair requirements as applicable.

•    Repair/replace/modify crankcase component parts.

•    Assemble, test for correct operation and adjust crankcase assembly components.

•    Correctly tagging, sealing and packaging completed components.

     Evidence of transferability of skills and knowledge related to repair is essential. This shall bedemonstrated through application across a number of different piston engine crankcaseassembly components. Ability to assess component serviceability and interpret partsrequirements will be necessary to supplement the required evidence. Capability to interpretinspection procedures and specifications (allowable limits) and apply them in practice iscritical. The application of testing procedures should also clearly indicate basic knowledge ofcrankcase assembly operation.

(b) Knowledge Evidence

     Evidence required to express competency in this unit must be related to and fulfil all of the requirements of the elements and performance criteria and include basic knowledge of:

•    How to obtain relevant MSDS.

•    The use of applicable items of PPE.

•    WHS procedures.

•    Component inspection and wear measurement procedures.

•    Non-destructive testing methods and application.

•    Component repair and overhaul procedures and processes.

Assessment Methods

(a) Recommendation

      Different working environments and conditions that may affect performance are admissible in this field. Crucial operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.



(b) Description

      Piston engine crankcaseassembly componentsinclude:

•    Crankshaft, gears, con rods and counterweights.

•    Camshaft, hydraulic tappets/cam followers and gears.

•    Propeller shaft, reduction drive gear and quill shaft.

•    Component gear drives/trains.

•    Crankcase castings, bearings, component mounting pads and studs.

•    Oil system components.

•    Supercharger and turbocharger components (where applicable to the enterprise).

•    Propeller governor (where applicable to the enterprise).

     Testing and adjustment:

•    Complex testing and adjusting of components, where required, will be carried out under supervision at the appropriate level.

      Procedures and requirements include:

•    Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.

•   The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

•   Competency should be assessed in the workplace or simulated workplace using tools and equipment stated in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.

•   Knowledge of crankcase assembly operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component 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 and the performance criteria are being achieved under routine supervision on at least one (1) item from each of the following groups:

•  Crankshaft, gears, con rods and counterweights.

•  Camshaft, hydraulic tappets/cam followers and gears.

•  Propeller shaft, reduction drive gear and quill shaft.

•  Component gear drives/trains.

•  Crankcase castings, bearings, component mounting pads and studs oil system components.

•  Supercharger and turbocharger components (may be omitted where not applicable to the enterprise).

•  Propeller governor (may be omitted where not applicable to the enterprise).

•  This shall be proven via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.
