Description
Employability Skills
Learning Outcomes and Application This unit of competency requires interpretation of structural repair and modification data to determine required action and to determine the compliance with airworthiness requirements of completed structural repairs or modifications. In addition, the performance of colour contrast dye penetrant non-destructive testing (NDT) on applicable components is included.Applications include both fixed and rotary wing aircraft.The unit covers some of the competencies required to progress from an Aircraft Maintenance Engineer (AME) at Certificate IV to the granting of a chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.The skills and knowledge covered by the units of competency listed in the MEA Aeroskills Training Package for Aircraft Maintenance Engineer at Certificate IV are prerequisite to the attainment of the elements of competency specified in this unit. This includes full coverage of the CASR Part 66 Syllabus subjects/topics listed in the Companion Volume CASA Interface.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency will be assessed in the training environment using a combination of practical exercises and scenarios. Applicable work plans should take account of applicable safety (including safe handling of heavy components) and quality requirements in accordance with the industry and regulatory standards.

The following conditions of assessment represent the requirements of CASA 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 elements and performance criteria of the unit of competency are being achieved across the tasks and practices listed in the Range of Conditions under supervision without intervention.

This shall be established via simulated activities at the CASR Part 147 Maintenance Training Organisation and performance during observed workplace activities.

The Assessor must meet the criteria specified in the CASR Part 147 Manual of Standards.

2.7

Results are recorded in accordance with standard enterprise and regulatory requirements

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:

interpreting damage limits and identifying applicable repair schemes

interpreting all requirements of modification drawings and assessing work against them

evaluating completed repairs and modifications for compliance with the applicable data and with airworthiness requirements

recognising weld defects

performing colour contrast dye penetrant NDT to confirm defects in applicable aircraft components

application of relevant WHS practices, including the use of MSDS and PPE.

The underlying skills inherent in this unit should be transferable across a range of repair and modification applications related to the structure of aircraft. It is essential that the repair and modification procedures take into account all applicable safety precautions. The ability to interpret repair scheme and modification requirements, including applicable specifications (allowable limits) and ensure that they are applied in practice is critical.

This must be demonstrated through the correct determination of repair requirements and the determination of compliance with repair schemes and modification drawings.

The ability to assess sound weld repairs must also be demonstrated.

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 at a post-trade level of:

application of regulatory requirements and of manufacturer’s requirements in the determination of structural maintenance needs

assessment of the extent of damage and an understanding of the need for a professional engineer to develop or extend a repair scheme where damage is beyond the limits of maintenance manual repair schemes, including the identification of relevant personnel and authorities

assessment of new equipment or component mounting requirements and an understanding of the need to have drawings and specifications developed by a professional engineer, including the identification of relevant personnel and authorities

the need for shoring and support to maintain aerodynamic shape and for safe performance of structural maintenance

the need for mensuration checks and the techniques used to perform them

how to determine welding requirements and the recognition of sound welds

the correct application of colour contrast dye penetrant NDT and the limitations of the testing method

dye penetrant test procedures:

relevant WHS precautions and how to obtain PPE and MSDS
