Release: 2

Assessment Requirements for MEA406 Repair/modify aircraft non-primary structural sheet metal components

Modification History

Release 2. Equivalent to MEA406 Repair/modify aircraft non-primary structural sheet metal components with amended prerequisite codes.

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 must include:

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

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, with expert qualified person guidance and in accordance with enterprise procedures, sheet metal repair scheme/modification drawings and hand sketches

using appropriate hand tools and machines under supervision to remove and assemble aircraft sheet metal components

performing under guidance and in accordance with enterprise procedures a range of routine sheet metal repair techniques, including metal scab patch repairs

applying corrosion removal/treatment techniques

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 basic repair techniques and the use of the standard repair manual/practices in a range of different routine repair situations will be necessary to supplement evidence of ability to plan and undertake component repair.

Knowledge 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 and include a basic knowledge of:

aircraft sheet metal component construction principles and repair techniques

how to obtain relevant MSDS

the use of applicable items of PPE

WHS procedures.

Assessment Conditions

Competency should be assessed in the work environment, using tools and equipment specified by aircraft 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.

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 qualified person guidance on at least one (1) item from each of the following groups:

removing corrosion by chemical and mechanical methods

restoring protective coatings

freehand precision hole generation

removing and installing fastening devices

routine repairs to non-primary structural sheet metal components.

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).
