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. | Prepare to fit avionic modification sheet metal components | 1.1 | Applicable sheet metal components are identified in accordance with applicable modification instructions and maintenance documentation |
| | 1.2 | All required materials and equipment are selected and organised in accordance with the applicable modification instructions and maintenance documentation |
2. | Fit avionic modification sheet metal components | 2.1 | Sheet metal components are fitted in accordance with the modification instructions, ensuring that aircraft standard practices are used and standard process requirements are carried out while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and personal protective equipment (PPE) |
| | 2.2 | Work area is cleaned of all waste material |
3. | Complete modification activities | 3.1 | Required documentation is accurately completed and correctly processed in accordance with 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 enterprise procedures, approved maintenance documentation and aircraft publications relating to aircraft sheet metal components
identifying various aircraft metals used for sheet metal components and their basic metallurgy properties by interpretation of markings, numbering systems or visual, chemical or mechanical means
handling and storing aircraft metals used for sheet metal components, including sealing agents, to industry standards
identifying aircraft sheet metal assembly fasteners (metal and non-metallic) by interpretation of markings, numbering systems, size, shape and colour
correctly interpreting, modification drawings and hand sketches
using appropriate hand tools and machines to fit avionic modification sheet metal components to the aircraft
freehand precision hole generation
applying corrosion prevention techniques during component fitment
restoring sealing and surface finishes.
The underlying skills inherent in this unit should be transferable into other areas that require similar techniques. It is essential that procedures take into account all safety precautions and quality requirements, standards and practices, and processes associated with assembly.
Evidence of knowledge about enterprise procedures relating to avionic modification incorporation and practices relating to associated sheet metal component installation will be necessary to supplement evidence of ability to fit a range of sheet metal components in a specific application.
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:
aircraft sheet metal component construction principles
identification of primary, secondary and tertiary structure
aircraft sheet metal assembly fasteners, their characteristics and identification
fits and clearances for fasteners
fitting methods for fasteners
use of grip pins
corrosion of aircraft structure and its prevention
application of surface finishes
relevant WHS procedures
how to obtain MSDS
use of PPE.
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 applicable general-purpose tools and test equipment found in most routine situations would be used where appropriate.
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 on the following range of sheet metal components:
doublers for the installation of antennas
brackets for the installation of avionic system components
racks for components, such as transmitters/receivers
hardware for the support of antenna cables and system electrical wiring.
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).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
