Aircraft structure major disassembly and reassembly

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.


Interpret specifications and organise materials


The procedure for assembly/disassembly of structure is determined in order to plan equipment use


Appropriate jigs, fixtures or bracing methods are selected to ensure maintenance of contour/structural integrity during disassembly/assembly operations


All components and equipment are organised


Prepare aircraft or sub-assembly for structural disassembly


Structure is supported with appropriate jigs, fixtures or bracing, as required


Structural components are removed, as required, to provide access


Disassemble aircraft structure or sub-assembly


Aircraft standard practices are applied in the removal of structural hardware and fasteners while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE)


Disassembled components are tagged, as required, to facilitate correct reassembly


Prepare components and tooling for assembly


Jigs and fixtures are set up to ensure accuracy of component assembly


Replacement component alignment is checked for conformance to specifications prior to fastener hole generation


Hole location/relocation is carried out in accordance with specification procedures and standard practices


Standard practices in hole generation sequencing are followed to ensure that assembly stress defects are not built in


Components are disassembled, cleaned, deburred and surface treatments applied prior to final assembly while observing all relevant WHS requirements, including the use of MSDS and items of PPE


Assemble aircraft structure or sub-assembly


Sealants and/or adhesives are selected and applied in accordance with assembly specifications or applicable documentation while observing all relevant WHS requirements, including the use of MSDS and items of PPE


Components are positioned and secured with appropriate temporary fastening devices for accurate assembly


Fasteners are selected and installed in accordance with assembly specifications or applicable manuals


Inspect completed assemblies


Assembled components are inspected to confirm dimensional accuracy and specifications are met


Checking or testing equipment is used, where appropriate, to ensure requirements are met


Aircraft mensuration is checked for compliance with applicable maintenance manuals, where necessary


Required documentation is completed and processed in accordance with standard enterprise procedures
