MEA392A
Disassemble aircraft piston engines

Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of hand skills, theory knowledge and maintenance publication procedures to disassemble aircraft piston engines during workshop repair and/or overhaul.

Applications include fixed and rotary wing aircraft piston engines and components.

This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It covers the competencies required to disassemble aircraft piston engines during repair and/or overhaul. The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 component theory knowledge and use maintenance publications to disassemble piston engines while applying all relevant safety precautions.

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

Evidence of transferability of skills and knowledge related to repair and overhaul is essential. This may be demonstrated through application across a number of different piston engines. Ability to assess component serviceability and interpret parts requirements will be necessary to supplement the required evidence. Capability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults 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 a representative range of the engine types maintained by the enterprise. 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 simulated work environment, using tools and equipment specified in maintenance documentation. It is also expected that general purpose tools and test equipment found in most routine situations would be used where appropriate.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

applying relevant work health and safety (WHS) procedures, including the use of material safety data sheets (MSDS) and personal protective equipment (PPE)

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

recognise state of serviceability and overhaul or repair requirements for piston engines

accurately and efficiently troubleshoot unserviceabilities and document the causes for piston engines and components

dismantle and inspect piston engine component parts for serviceability

identify and initiate procurement for piston engine component parts/hardware that are discarded

identify and process engine components that require detailed inspection, repair, overhaul or modification

Required knowledge

Required knowledge includes:

how to obtain relevant MSDS

the use of applicable items of PPE

WHS procedures

fault diagnosis techniques

system and component operation

engine cleaning and disassembly procedures and component inspection for serviceability, including identification of life expired components

enterprise documentation requirements

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Piston engine

Piston engines may include the engine assembly and components that comprise a quick engine change unit. Engine types include all cylinder arrangements and fuel types (aviation gasoline, two stroke or diesel)

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team-related activities

Procedures and requirements

Procedures and requirements refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Engine defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers 
Piston engine is inspected in accordance with maintenance publications to establish serviceability state and confirm defects, if necessary 
Piston engine build status is determined and quick engine change (QEC) components are recorded in accordance with standard enterprise procedures 
Modification status and engine operating hours are clearly established from the engine log book to assist in determining the repair or overhaul requirements for the engine 
Extent of overhaul or repair is identified and documented in accordance with standard enterprise procedures 
Where applicable, QEC components are removed from the engine, maintenance requirements are determined, and necessary documentation is raised and packaged with the components 
Any removed QEC components not requiring maintenance are correctly labelled and stored for reinstallation 
Engine is installed in work stand and engine is cleaned 
Engine is disassembled in accordance with maintenance publication and/or enterprise procedures 
Removed components are cleaned, tagged and inspected for seviceability in accordance with enterprise procedures 
Components that are not to be reinstalled are disposed of in accordance with enterprise procedures and action is initiated to obtain replacement components 
Components to be re-fitted are processed for detailed inspection, repair/overhaul and/or modification, as required
