Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

1. Prepare to dismantle, inspect, maintain and assemble basic mechanical components or parts

1.1. Components are removed and/or disassembled in accordance with enterprise procedures, relevant maintenance documentation and qualified person guidance

1.2. Maintenance and/or repair requirements as defined by the qualified person, enterprise procedures and the relevant maintenance documentation, are understood

1.3. Tagging and repair instructions are accurately specified in accordance with enterprise procedures and qualified person directions for parts requiring specialist repair

1.4. Appropriate materials, tools, equipment and assembly or fabrication jigs, where applicable, are selected and prepared for the particular maintenance and repair requirements in accordance with enterprise procedures and relevant maintenance documentation

2. Maintain and/or repair mechanical components or parts

2.1. Routine maintenance, repair or modification procedures are carried out, as approved by relevant manufacturers' bulletins or procedures, in accordance with required enterprise procedures and specifications

2.2. Mechanical component parts are assembled within specified tolerances in accordance with enterprise procedures and the appropriate maintenance documents

2.3. Where applicable and as required by the qualified person, assistance is provided in the final adjustment of components to confirm serviceability

3. Complete maintenance/repair activities

3.1. Required documentation is completed and processed in accordance with standard enterprise procedures

3.2. Maintained/repaired or modified components are tagged, sealed and packaged within specified procedures

Required skills 

Look for evidence that confirms skills in:

• applying relevant OHS procedures
• using relevant maintenance documentation, specifications and aircraft/component manuals to:

• recognise state of serviceability and standard/routine repair requirements for the range of mechanical components listed in the Range Statement
• identify requirements under the guidance of a qualified person and complete routine repairs and/or modifications
• adjust components under qualified person guidance as required
• where post-assembly testing is applicable, under guidance and in the training environment, set up components for testing and perform tests
• correctly tag, seal and package completed components

Required knowledge 

Look for evidence that confirms knowledge of:

• component operation at a basic level
• standard/routine repair procedures and processes
• relevant OHS practices
• how to obtain MSDS
• use of PPE

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to dismantle, inspect, maintain and assemble aircraft mechanical components or parts under qualified person guidance while observing all relevant safety precautions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The underlying skills inherent in this unit should be transferable across a range of maintenance and repair applications associated with aircraft components. It is essential that the relevant enterprise procedures are interpreted and applied to ensure quality and safety standards are achieved.

Evidence of transferability of skills and knowledge related to enterprise procedures for maintenance and repair is essential. This may be demonstrated through application across a number of different aircraft components. Ability to assess component serviceability under qualified person guidance and interpret parts requirements will be necessary before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

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 are being achieved under qualified person guidance on a representative range of components or parts listed in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.

Context of and specific resources for assessment 

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 found in most routine situations would be used where appropriate.

Method of assessment 

Guidance information for assessment 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Routine work 

Routine work is 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)

Outcomes 

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

Maintain and /or repair /modify basic components 

Maintain and/or repair/modify basic components, such as:

• cables, pulleys, chains, sprockets, gear drives, control rods, bellcranks and links

Scope of work 

Note that the scope of any repair or modification and the procedure to be followed will be provided by the qualified person, and be within the scope of the skills and knowledge included in the unit of competency MEA109B Perform basic hand skills, standard trade practices and fundamentals in aviation maintenance

Repair 

Repair comprises replacement of parts, such as:

• eye-ends, tubes, bearings and bushes

Maintain 

Maintain involves cleaning, inspection for wear or damage and routine adjustment and lubrication where applicable in accordance with enterprise procedures

Application 

Work can relate to:

• routine scheduled or unscheduled maintenance activities performed under qualified person guidance in accordance with enterprise procedures and applicable maintenance documentation
• tasks performed either autonomously or as part of a team and under the guidance of a qualified person

Procedures and requirements 

Refer to procedures specified by manufacturers, regulatory authorities or the enterprise
