Unit of Competency MEA387 - Test gas turbine engines and engine modules after overhaul or repair
Description
Employability Skills
Learning Outcomes and Application This unit of competency requires application of hand skills, theory knowledge and maintenance publication procedures to test run aircraft gas turbine engines and engine modules in engine test stands following overhaul or repair in workshops during the performance of scheduled or unscheduled maintenance. Testing may be performed individually or as part of a team.Applications include turbo-jet, turbofan, turboshaft, turboprop engines and engine modules, or auxiliary power units.The unit is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency should be assessed in the work environment or simulated work environment in an applicable engine test stand. It is also expected that general-purpose tools and test equipment found in most routine situations would be used where appropriate.

The application of testing procedures should clearly indicate knowledge of system operation. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot engine or module 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.

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 a range of engine/module test runs that are representative of the testing performed within 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).

4.3

Unserviceable engines or modules are returned to workshop in accordance with standard enterprise procedures for rectification or rework

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

using relevant MSDS and items of PPE

using relevant maintenance manuals and standard enterprise procedures to:

prepare engines or modules for test running

install engines in test stands

test run and trim engines, where applicable

record engine operating parameters

remove engines from the test stand

complete documentation

configuring and inhibiting serviceable engines and modules for transport or storage.

The underlying skills inherent in this unit should be transferable across a range of repair and/or overhaul applications associated with gas turbine engines and/or modules. It is essential that the maintenance procedures (including the use of correct fuels and lubricants) are interpreted and applied to ensure quality and safety standards are achieved.

This shall be demonstrated through application across a number of gas turbine engine and/or module test runs. Capability to interpret test procedures and specifications (allowable limits) and apply them in practice is critical.

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

test stand operation

engine and module test requirements

engine operating parameters and adjustment methods.
