This unit of competency requires application of hand skills and use of maintenance documentation to dismantle, inspect, maintain and assemble aircraft mechanical components or parts during scheduled or unscheduled maintenance under the guidance of a qualified person. Work under the guidance of a qualified person may be performed individually or as part of a team.

Applications include components or parts either attached to the aircraft or in a workshop. It does not include work on hydraulic and pneumatic components or parts.

The unit is part of a Mechanical Certificate II training pathway.

The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation safety Authority (CASA).

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 practices, including the use of MSDS and PPE

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 of Conditions

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 tagging, sealing and packaging completed components.

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.

This shall be demonstrated through application across a number of different aircraft components as listed in the Assessment Conditions.

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:

component operation at a basic level

standard/routine repair procedures and processes

relevant WHS practices

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 general and special-purpose tools found in most routine situations would be used where appropriate.

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.

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 a representative range of basic components, including:

cables

pulleys

chains

sprockets

gear drives

control rods

bellcranks and links.

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).

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
