The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

A person who demonstrates competency in this unit must be able to apply hand skills and use maintenance publications to remove and install engines and engine system components on fixed or rotary wing aircraft while applying all relevant safety precautions

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The underlying skills inherent in this unit should be transferable into other units that require similar techniques It is essential that safety precautions applicable to engines and engine systems being maintained are fully observed understood and complied with including allowance for the effect on aircraft centre of gravity when engines are removed Awareness must be demonstrated of dual inspection requirements associated with work on engine control systems

Evidence of transferability of skills and knowledge related to removal and installation is essential This may be demonstrated through removal and installation of a representative range of engines and engine system components An understanding of component attachment methods and the need for adjustment rigging and system operation as it relates to the work must be demonstrated before undertaking any action The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards

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 are being achieved under routine supervision on at least one item from each of Groups to listed in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide

Context of and specific resources for assessment

Competency should be assessed in the work environment or by the use of simulated activities using tools and equipment specified in aircraft maintenance manuals It is also expected that general purpose tools test and ground support equipment found in most routine situations would be used where appropriate

Method of assessment

Guidance information for assessment

Individuals being assessed who have already attained MEAA Maintain basic light aircraft engines and propellers will have satisfied the requirements of this unit with regard to common Range Statement variables Log of Industrial Experience and Achievement records relating to MEAA Maintain basic light aircraft engines and propellers may be accepted as also meeting the evidence requirements for this unit in the applicable common areas

Individuals being assessed who have already attained MEA353A Maintain basic light aircraft engines and propellers, will have satisfied the requirements of this unit with regard to common Range Statement variables. Log of Industrial Experience and Achievement records relating to MEA353A Maintain basic light aircraft engines and propellers, may be accepted as also meeting the evidence requirements for this unit in the applicable common areas.
