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 WHS practices, including lifting and handling heavy components
using MSDS and PPE
using relevant maintenance documentation and aircraft manuals to:
correctly remove and install engines, engine change units and auxiliary power units (APUs)
prepare removed engines for transportation and/or storage
locate and correctly remove and install the range of engine system components listed in the Range of Conditions
identifying the requirement for adjustment and rigging of systems and controls after the installation of engines or system components.
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 as listed in the Assessment Conditions.
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:
removal and installation procedures for aircraft:
engines
engine change units
APUs
engine inhibiting and de-inhibiting procedures
layout, installation and connection of components of:
fuel systems
lubrication systems
air systems
super and turbo charging systems
exhaust systems
ignition and igniter systems
starting systems
fire protection systems
accessories and associated drives
engine control system component removal and installation, including the requirement for rigging and for the independent inspection of work performed
engine maintenance documentation and manuals
relevant WHS practices, including those relating to the lifting and handling of heavy items
how to obtain MSDS
use of PPE
relevant maintenance manuals
relevant regulatory requirements and standard procedures.
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 applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.
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.
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 on at least one (1) item from each of the following groups:
engine change unit or auxiliary power unit (turbo-prop, turbofan, turboshaft, turbojet, piston)
fuel, oil and air system (or induction and super/turbo charger systems in the case of piston engine) components
engine control system components
ignition or igniter system components
starting system components
fire protection system components.
accessories and associated drives.
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.
Individuals being assessed who have already attained MEA353 Maintain basic light aircraft engines and propellers will have satisfied the requirements of this unit with regard to common Range Statement variables. The Log of Industrial Experience and Achievement records relating to MEA353 Maintain basic light aircraft engines and propellers may be accepted as also meeting the evidence requirements for this unit in the applicable common areas.
