Release 1

MEA395A Reassemble aircraft piston engines

Modification History

Release 1 - New unit of competency. Covers components of MEA388A - Not equivalent

Unit Descriptor

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).

Application of the Unit

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.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Assessment of performance is to be consistent with the evidence guide.

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

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.
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

Evidence Guide

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.
