Evaluate aircraft structure

Assessment tool

Version 1.0
Issue Date: May 2024

This unit of competency applies to aircraft primary, secondary and tertiary structure and related structural components. It involves evaluation of structure and structural components for compliance with design standards and with airworthiness regulatory requirements within both civil and military environments.

Also covered is documentation of the evaluation process within management systems, such as configuration management (CM) and integrated logistic support (ILS).

It is suitable for people working as paraprofessionals within aircraft design teams, within the engineering departments of aircraft maintenance organisations or employed within Continuing Airworthiness Management Organisations (CAMOs) and Approved Engineering Organisations (AEOs), and for those pursuing qualifications or careers in those fields.

This 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).

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

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:

identifying WHS, regulatory and risk management procedures, structural design and construction principles, and ageing aircraft structure inspection and maintenance requirements

determining and confirming:

parameters and context of tasks

chain of responsibility

personal functions and responsibilities

team and support functional group interdependencies and communications

appropriate qualifications and delegations

appropriate support, including technical and professional assistance

investigating associated CM and ILS requirements and drafting required data

assessing and applying:

basic aircraft structural analysis and design procedures

design standards

regulatory requirements

graphics skills and techniques

evaluating proposed modification and repair schemes

reporting and documenting results of scoping, principles and techniques identification and evaluation of applications.

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:

aircraft structural design and construction:

design standards and manufacturerâ€™s stress analysis

structural materials

structural hardware

construction and assembly methods

sealants and surface finishing schemes

basic design principles for:

structural modifications

repair schemes and extensions to existing schemes

ageing aircraft structural inspection and maintenance requirements

airworthiness regulator design standards

compliance requirements of the WHS Act and regulations, codes of practice, standards and risk assessment

scope of trade, technical and professional support services required in aircraft structural applications

management data interface with CM and ILS.

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used that reflects realistic workplace situations and conditions.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessors must be satisfied that the candidate can competently and consistently:

identify and apply WHS, regulatory and risk management procedures

determine parameters and context of tasks, personal, team, technical and professional assistance and support, personnel functions and responsibilities, and chain of responsibility

investigate sustainability implications of aircraft structure as specified in CM and/or ILS requirements

assess and apply basic aircraft structural design and maintenance/repair requirements, and graphics skills and techniques

evaluate aircraft structure and structural components for compliance with WHS and airworthiness regulatory requirements

report and document results, including provision of CM and ILS input data.

Assessment may be in conjunction with assessment of other units of competency where required.

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
