Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

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.

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.

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential 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.

Sheet metal repairs include:

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

Work environment:

Work is undertakeneither autonomously or as part of a team and under the guidance of a qualified person.

Routine workis carried out using basic operational knowledge and a defined range of skills (‘routine’ work is that which follows a customary or regular course of procedure). All work outcomes are achieved by applying known solutions chosen from a limited range of pre-determined options consistent with enterprise procedures. This includes accepting responsibility for own work in terms of quality of outcomes using pre-determined specifications of quality.

Competency application:

Competency applies tothe routine repair and/or minor modification of aircraft non-primary structural sheet metal components. Note that ‘primary structure/structural’ refers to all components of an aircraft, the failure of which would seriously endanger safety, for example, wing or tailplane spars, main fuselage frames, engine bearers, portions of skin that are highly stressed. ‘Non-primary’ refers to any other items. Note also that the scope of any modification and the procedure to be followed will be provided by the qualified person.

Scope:

Repairs/modification undertaken are limited tothe scope of skills and knowledge included in the unit of competency MEA109 Perform basic hand skills, standard trade practices and fundamentals in aviation maintenance

Procedures and requirements include:

Industry standard specified by manufacturers, regulatory authorities or the enterprise
