List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. | Inspect aircraft structure | 1.1 | Relevant maintenance documentation and modification status, including defect reports, where relevant, are used to identify specific inspection requirements |
| | 1.2 | Appropriate preparation and access to the aircraft structure is undertaken to allow for proper inspection in accordance with maintenance documentation while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE) |
| | 1.3 | Aircraft structure is visually or physically checked for signs of deformation, defects or damage in accordance with maintenance documentation and approved procedures while observing all relevant WHS requirements, including the use of MSDS and items of PPE |
| | 1.4 | Damage or defects are assessed against damage or wear limits specified by structural repair manual or other approved data to determine if repair or replacement is required |
| | 1.5 | Maintenance documentation is completed and processed in accordance with standard enterprise procedures |
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 all relevant WHS procedures, including the use of PPE and MSDS
using approved maintenance documentation and aircraft publications relating to aircraft structure
identifying various aircraft metals and their basic properties
identifying potential causes of structural failure
demonstrating appropriate cleaning procedures to enable structure inspection
demonstrating correct inspection procedures, in particular pressurised aircraft, in accordance with aircraft and procedures manuals
performing aircraft mensuration and alignment checks
identifying damage to aircraft metallic (ferrous and non-ferrous) structures and/or components by way of:
impact
fatigue
corrosion
identifying the various forms of structural corrosion, stating the causes and structural effects of corrosion on aircraft
identifying composite materials used in aircraft construction, associated safety precautions and hazards
inspecting damage and assessing composite components/structures for:
impact damage
fatigue.
The underlying skills inherent in this unit should be transferable across a range of structural inspections associated with aircraft maintenance. It is essential that the procedures take into account all aircraft and personal safety precautions relating to aircraft structure.
Evidence is required of the ability to interpret and apply aircraft structural inspection requirements. This may be demonstrated through application across a range of structural components and materials. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical. The application of the procedures should also clearly indicate knowledge of structural flight loads.
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 construction principles
structural component attachment methods
describing the construction methods used in:
fuselage sections
wing sections
engine nacelles and mounts
windows and window frames
doors, locks and access panels in pressurised and unpressurised aircraft
defining of structural terms, i.e. safe life, damage tolerant, failsafe, stress, strain, shear and cycles
inspection requirements for metal and composite structure, including:
ageing aircraft inspection requirements
safe life structure
damage tolerant structure
fail safe structure
procedures and methodology for performing aircraft mensuration and alignment checks
describing NDT methods and application of the various techniques
describing construction methods of, and assessing common defects in, aircraft plastic transparencies
describing basic constructional features of, and assessing common defects in, glass windscreens
defining the terms associated with composite materials
WHS procedures
relevant PPE
how to obtain MSDS.
Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance documentation. It is also expected that general-purpose tools and test equipment found in most routine situations would be used where appropriate.
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 routine supervision on at least one (1) task from each of the following groups:
preparation for non-destructive testing (NDT) (access to relevant structural zones and components)
inspection of:
non-ferrous and ferrous alloys and composite (FRP) materials used in aircraft construction
structural fastening and attachment hardware and/or devices
seals and sealants
glass and moulded plastics
application of NDT techniques
doors, hinges and locking mechanisms for damage/misalignment
inspections applicable to each of safe life, damage tolerant and fail safe structure relevant to enterprise
ageing aircraft inspection programs.
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).
