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 | Mechanical components are inspected and/or operated through prescribed test procedures to establish serviceability or confirm defects, as required |
| | 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. | Troubleshoot mechanical components | 2.1 | Available information from maintenance records and test results is used, where necessary, to assist in fault determination |
| | 2.2 | Logical processes are used to ensure efficient and accurate troubleshooting |
| | 2.3 | Specialist advice is obtained, where required, to assist with, or confirm, the fault and rectification requirement |
| | 2.4 | Mechanical component faults are located and the causes of the faults are clearly identified |
| | 2.5 | Fault rectification requirements are determined to assist in planning the repair |
3. | Dismantle and inspect mechanical component parts | 3.1 | Mechanical component parts are dismantled in accordance with maintenance manuals while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE) |
| | 3.2 | Component parts are assessed for serviceability in accordance with the relevant maintenance documentation |
| | 3.3 | Parts requiring specialist repair are tagged and repair instructions are specified in accordance with standard enterprise procedures |
| | 3.4 | Parts requiring non-destructive testing (NDT) are prepared for testing in accordance with the relevant maintenance documentation |
| | 3.5 | Parts lists are compiled and processed in accordance with standard enterprise procedures |
4. | Repair and/or modify mechanical | 4.1 | Component parts are repaired or replaced in accordance with the relevant maintenance documentation |
| | 4.2 | Modification of components or parts is undertaken, where required, by relevant manufacturer's bulletins or procedures |
5. | Assemble, test and adjust mechanical components | 5.1 | Mechanical component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents while observing all relevant WHS requirements, including the use of MSDS and items of PPE |
| | 5.2 | Components are adjusted, tested or calibrated to operate within prescribed specifications |
| | 5.3 | Finished components are tagged, sealed and packaged in accordance with standard enterprise procedures |
| | 5.4 | 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
using MSDS and applicable items of PPE
using relevant maintenance documentation and aircraft/component manuals relating to mechanical system components to:
recognise state of serviceability and overhaul or repair requirements
test and accurately and efficiently troubleshoot unserviceabilities and document the causes
dismantle and inspect component parts for serviceability and identify repair requirements as applicable
repair/replace/modify component parts
assemble, test for correct operation and adjust components.
The underlying skills inherent in this unit should be transferable across a range of repair and overhaul applications associated with aircraft mechanical components. It is essential that the relevant procedures are interpreted and applied to ensure quality and safety standards are achieved.
This shall be demonstrated through application across a number of different aircraft components. Ability to assess component serviceability and interpret parts requirements will be necessary before undertaking any action.
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 correct use of PPE
WHS procedures
fault diagnosis and component part inspection techniques
system and component operation
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 and special-purpose tools and test equipment found in most routine situations would be used where appropriate.
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 and performance criteria of the unit of competency are being achieved under routine supervision on at least one (1) component from each of the following groups:
gear boxes and transmissions (except for helicopter components which are covered by MEA390 Repair and/or overhaul rotary wing dynamic components)
screwjacks
mechanical actuators
control rods, bellcranks, walking beams and links.
This must include demonstration of the following repair processes:
finishing or re-finishing of metal surfaces through processes, such as polishing and lapping
removal of corrosion within maintenance manual limits
replacement of seals and gaskets
replacement of bearings
application of surface treatments, such as alodining
restoration of paint finishes
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).
