Issue Date: May 2024


Qualification -
Unit of Competency MEA395A - Reassemble aircraft piston engines
Description This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It covers the competencies required to reassemble aircraft piston engines during repair and/or overhaul. Note that this relates to the bare engine and does not include the assembly of a quick engine change (QEC) unit. For QEC build-up refer to unit MEA396A Assemble aircraft piston engine quick engine change unit.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).
Employability Skills This unit contains employability skills
Learning Outcomes and Application This unit requires application of hand skills, theory knowledge and maintenance publication procedures to reassemble aircraft piston engines during workshop repair and/or overhaul.Applications include fixed and rotary wing aircraft piston engines and components.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 reassemble 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/sub-assembly 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. The application of adjustment procedures should also clearly indicate knowledge of system operation. 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:

identify the required engine build level and configuration

recognise state of serviceability of the required sub-assemblies, components, hardware and plumbing

reassemble the engine and adjust components and linkages

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 reassembly and component adjustment 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 sub-assemblies and components

Sub-assemblies and components may include:

crankcase assembly

cylinder assemblies

external lubrication system components

propeller governor (where applicable)

fuel system components

ignition system components

exhaust system components

turbocharger and waste gate (where applicable)

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team-related activities

complex testing and adjusting of components, and where this is undertaken, may be carried out under supervision at the appropriate level

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.
