Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

MEA392A - Disassemble aircraft piston engines

What evidence can you provide to prove your understanding of each of the following citeria?

Determine requirements

  1. Engine defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
  2. Piston engine is inspected in accordance with maintenance publications to establish serviceability state and confirm defects, if necessary
  3. Piston engine build status is determined and quick engine change (QEC) components are recorded in accordance with standard enterprise procedures
  4. Modification status and engine operating hours are clearly established from the engine log book to assist in determining the repair or overhaul requirements for the engine
  5. Extent of overhaul or repair is identified and documented in accordance with standard enterprise procedures
Engine defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers

Instructions to Assessors

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 disassemble 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 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. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component 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.

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.

Method of assessment

Guidance information for assessment

Required Skills and Knowledge

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:

recognise state of serviceability and overhaul or repair requirements for piston engines

accurately and efficiently troubleshoot unserviceabilities and document the causes for piston engines and components

dismantle and inspect piston engine component parts for serviceability

identify and initiate procurement for piston engine component parts/hardware that are discarded

identify and process engine components that require detailed inspection, repair, overhaul or modification

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 cleaning and disassembly procedures and component inspection for serviceability, including identification of life expired components

enterprise documentation requirements

Range Statement

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

Piston engines may include the engine assembly and components that comprise a quick engine change unit. Engine types include all cylinder arrangements and fuel types (aviation gasoline, two stroke or diesel)

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team-related activities

Procedures and requirements

Procedures and requirements refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise
