Unit of competency

Modification History

Release 2. Equivalent to MEA396 Assemble aircraft piston engine quick engine change unit with amended prerequisite codes.

Application

This unit of competency requires application of hand skills, theory knowledge and maintenance publication procedures to assemble aircraft piston engine quick engine change (QEC) units following engine repair and/or overhaul.

Applications include fixed and rotary wing aircraft piston engines and components. Work can be performed individually or as a member of a team.

This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. 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).

Assessment requirements

Modification History

Release 2. Equivalent to MEA396 Assemble aircraft piston engine quick engine change unit with amended prerequisite codes.

Performance Evidence

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 relevant WHS procedures, including the use of MSDS and PPE
  • using relevant maintenance documentation, enterprise procedures, specifications and aircraft/component manuals to:
  • identify the required QEC build level and configuration
  • recognise state of serviceability of the QEC components, hardware and plumbing
  • assemble the QEC and adjust components and linkages.

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 engine QECs. 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. The application of adjustment procedures should also clearly indicate knowledge of system operation.

Knowledge Evidence

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:

  • how to obtain relevant MSDS
  • the use of applicable items of PPE
  • WHS procedures
  • fault diagnosis techniques
  • system and component operation
  • QEC assembly and component adjustment requirements.

Assessment Conditions

  • 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.
  • 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) 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 (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).
