Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Components to be maintained and/or repaired/modified include:	Hoses Pipes Simple check or shutoff valves Basic hydraulic and pneumatic actuators and valves
Routine work:	Is carried out using basic operational knowledge and a defined range of skills (‘routine’ work is that which follows a customary or regular course of procedure)
Work outcomes:	Are achieved by applying known solutions chosen from a limited range of pre-determined options consistent with enterprise procedures. This includes accepting responsibility for own work in terms of quality of outcomes using pre-determined specifications of quality
Scope of work:	Note that the scope of any repair or modification and the procedure to be followed will be provided by the qualified person, and be within the scope of the skills and knowledge included in the unit of competency MEA109 Perform basic hand skills, standard trade practices and fundamentals in aviation maintenance
Maintain includes:	Cleaning, inspection for wear or damage and consequent replacement of parts, and routine adjustment and lubrication, where applicable, in accordance with enterprise procedures
Procedures and requirements include:	Industry procedures specified by manufacturers, regulatory authorities or the enterprise

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 practices, including the use of MSDS and PPE

using relevant maintenance documentation, specifications and aircraft/component manuals to:

recognise state of serviceability and standard/routine repair requirements for the range of hydraulic and pneumatic components listed in the Range of Conditions

identify requirements under the guidance of a qualified person and complete routine repairs and/or modifications

adjust components under expert guidance as required

where post-assembly testing is applicable, set up components for testing and have a basic understanding of the test procedures

correctly tagging, sealing and packaging completed components.

The underlying skills inherent in this unit should be transferable across a range of maintenance and repair applications associated with aircraft components. It is essential that the relevant enterprise procedures are interpreted and applied to ensure quality and safety standards are achieved.

This shall be demonstrated through application across a number of different aircraft components as listed in the Assessment Conditions.
