List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. | Determine requirements | 1.1 | Component defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers |
| | 1.2 | Crankcase assembly components are inspected and/or operated through prescribed test procedures to establish serviceability and confirm defects, if necessary, while observing relevant work health and safety (WHS) procedures, including the use of material safety data sheets (MSDS) and personal protective equipment (PPE) |
| | 1.3 | Modification status is clearly established to assist in determining the overhaul requirements for the components |
| | 1.4 | Extent of overhaul or repair is identified and documented in accordance with standard enterprise procedures |
2. | Dismantle and inspect piston engine crankcase assembly components/parts | 2.1 | Crankcase assembly component parts are dismantled in accordance with maintenance manual and/or enterprise procedures while observing relevant WHS procedures, including the use of MSDS and PPE |
| | 2.2 | Component parts are assessed for serviceability in accordance with the relevant maintenance documentation |
| | 2.3 | Parts requiring specialist repair are tagged and repair instructions are specified in accordance with standard enterprise procedures |
| | 2.4 | Parts requiring non-destructive testing (NDT) are prepared for testing in accordance with the relevant maintenance documentation |
| | 2.5 | Parts lists are compiled and processed in accordance with standard enterprise procedures |
3. | Repair and/or modify piston engine crankcase assembly components or parts | 3.1 | Component parts are repaired or replaced in accordance with the relevant maintenance documentation |
| 3.2 | Modification of components is undertaken where required by reference to relevant manufacturer's bulletins or procedures, regulatory requirements and/or customer requirements while observing relevant WHS procedures, including the use of MSDS and PPE |
4. | Assemble, test and adjust piston engine crankcase assembly components | 4.1 | Crankcase assembly component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents while observing relevant WHS procedures, including the use of MSDS and PPE |
| | 4.2 | Components are tested, adjusted or calibrated to operate within prescribed specifications |
| | 4.3 | Crankcase assembly is prepared for engine reassembly |
| | 4.4 | Where components are not to be assembled into an engine the finished components are tagged, sealed and packaged in accordance with standard enterprise procedures |
| | 4.5 | Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures |
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 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 be demonstrated through application across a number of different piston engine crankcase assembly components. Ability to assess component serviceability and interpret parts requirements will be necessary to supplement the required evidence. Capability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical. The application of testing procedures should also clearly indicate knowledge of crankcase assembly operation.
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include 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.
Competency should be assessed in the work environment, or simulated work environment, using tools and equipment specified in maintenance documentation. It is also expected that general purpose tools and test 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.
The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
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 established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
