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).
Notes
Elements and Performance Criteria
1 Prepare to assemble piston engine
- 1.1 Engine build requirements are correctly interpreted and matched by part and serial numbers
- 1.2 Correct engine sub-assemblies and components are gathered for engine assembly and their serviceability state and modification status is confirmed in accordance with the relevant maintenance documentation and quality procedures
- 1.3 Required hardware and plumbing is obtained and confirmed as approved items
2 Reassemble piston engine
- 2.1 Piston engine sub-assemblies and components are prepared for reassembly in accordance with maintenance manual and/or enterprise procedures
- 2.2 Components are assembled and adjusted in accordance with the maintenance manual and/or enterprise procedures
- 2.3 Engine is assembled and components and linkages are adjusted in accordance with maintenance data requirements
- 2.4 Reassembled engine is prepared for testing
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
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

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.
