(a) Performance Evidence

      Evidence required to demonstrate competency in this unit should be of interest and meet all requirements of the elements and performance criteria under the specified conditions assessment, and should 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. 

• Performing metal, composite and fabric minor repairs classified as elementary maintenance. 

• Restoring aircraft structure sealing and surface finishes. 



Using relevant maintenance documentation and aircraft manuals to: 

• Remove and install structural and non-structural components. 

• Remove and install aircraft interior fittings. 

• Remove and install doors, door seals, windows and transparent panels. 

• Checking and adjusting all doors and access panels, including locking mechanisms. 

•    Removing and installing emergency equipment. 

      It is essential that the procedures take account of all aircraft and personal safety precautions related to the airframe. Evidence of transferability of skills and knowledge related to the inspection, testing and minor minor repairs to the aircraft structure, except primary structure is essential. 

This can be demonstrated by applying through a number of aircraft structures or types of aircraft. Ability to interpret inspection procedures and minor repair and apply them in practice is essential.

(a) Recommendation

(b) Description

      N/A

 

      The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement. Competition should be assessed in the workplace or work environment simulated using tools and equipment specified in the maintenance documentation. It is also expected that the 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 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. 

• Sstructural 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. 

• Ane (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: 

• Removable components of wings, tail booms, pylons, empennage, skids, fairings and nacelles. 

• Removable components or sections of non-pressurised fuselages. 

• Non-pressurised fuselage entry, cargo, access doors and associated seals (including checking and adjustment of all doors and access panels and associated locking mechanisms). 

• Non-pressurised fuselage windows and transparent panels. 

• 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.
