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 selection and use of MSDS and applicable items of PPE
demonstrating appropriate cleaning procedures to enable structure inspection
demonstrating correct inspection procedures in accordance with aircraft and procedures manuals
identifying damage to aircraft metallic (ferrous and non-ferrous) structures and/or components by way of impact, fatigue or the various types of corrosion
inspecting damage and assessing composite components/structures
identifying various aircraft metals and their basic properties
identifying composite materials used in aircraft construction, associated safety precautions and hazards
using appropriate hand tools and machines, including riveting equipment, drilling equipment, aligning tools and material fasteners (grip pins)
applying correct removal, installation and repair techniques for a range of rivets (blind and solid) using hand, squeeze and pneumatic situations

It is essential that the procedures take into account all aircraft and personal safety precautions relating to aircraft structure.
Evidence of transferability of skills and knowledge related to inspection, testing and minor repair of aircraft structure other than primary structure is essential. This may be demonstrated through application across a number of aircraft structures or aircraft types. Ability to interpret inspection and minor repair procedures and apply them in practice is critical.
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:

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-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 across the variables in the Range of Conditions as follows:
inspection and/or testing of at least one (1) item from each of the following groups:
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
preparation for 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
inspection after abnormal events
recognition of each type of damage:
impact damage
fatigue cracking
corrosion
delamination of composites and bonded structures
one (1) minor elementary maintenance repair task from each of the following groups:
repair of non-structural fairings, cover plates and cowlings
stop drilling of cracks and bonding to acrylic or Perspex windscreens
restoration of preservative or protective materials
one (1) removal and installation task from each of the following groups:

floor panels.
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 National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
The competency elements and performance criteria also cover some of those required for units MEA304 Remove and install non-pressurised aircraft structural and non-structural components and MEA339 Inspect, repair and maintain aircraft structures. Refer to those units for details of credits that may be granted during assessment of those units.
