Assessment Requirements for MEA367 Repair/modify aircraft composite structure using cold bonding

Modification History

Release 1 - New unit of competency

Performance Evidence

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 relevant WHS procedures, including the use of MSDS and applicable items of PPE

using approved maintenance documentation and aircraft publications relating to aircraft structure

identifying composite component applications in aircraft structures

identifying various aircraft composite materials/resins and their basic properties by interpretation of markings and visual means

handling and storing of composite materials to industry standards

assessing composite component damage using visual and tap test methods

relative advantages and disadvantages of hot and cold cure

performing composite component repairs using cold cure adhesives:

external patch repair

scarf repair

stepped repair

wet lay-up repair

composite fastener hole repair

metal to metal and metal to composite bonding

correctly interpreting and/or producing repair scheme/modification drawings/sketches

using appropriate hand tools and machines to disassemble and assemble aircraft composite components, parts, sections and skin, including extraction/installation equipment, drilling/cutting equipment, and material fasteners.

The underlying skills inherent in this unit should be transferable across the range of different material applications applicable to cold curing. It is essential that specific aspects of the laying up and curing process for aircraft composite materials are checked to ensure quality and safety standards are achieved in this area. Correct checking and wearing of PPE is critical.

Evidence of knowledge about repair techniques and the use of the standard repair manual in a range of different repair situations will be necessary to supplement evidence of ability to plan and undertake component repair. Ability to apply different materials and curing cycles, including composite to composite and composite to metal components, will be necessary to indicate competency in preparing and curing composite materials.

Knowledge Evidence

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 and the causes of structural damage, including metal fatigue and corrosion

structural fatigue preventative measures

composite terminology and materials used in both hot and cold bonding

composite component construction and repair methods, including structural assembly fastener types, specifications and identification

procedures for the design and approval of repair schemes and modifications

composite material storage requirements

sealants used in aircraft structure and their application and handling

paints and finishes for composite structure

WHS precautions associated with repair of aircraft structure

MSDS

PPE.

Assessment Conditions

Competency should be assessed in the workplace or simulated workplace. 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 of the unit of competency and the performance criteria are being achieved under routine supervision using materials from each of:

cold cure or wet lay-up (using either fibreglass or carbon graphite)

core materials (using one of aluminium, nomex or foam)

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).

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.
