E2.3 Excluding Structural Components – Pressurised Aircraft
for DASR B1.1
Delivered via
RPL and Gap Assessment Pathway Self-Directed for Experienced Engineers
This pathway is designed for experienced, self-motivated aircraft maintenance engineers.
Knowledge is assessed through an individualised combination of Recognition of Prior Learning (RPL) and targeted knowledge gap assessments, and Practical competency (performance evidence) is assessed via RPL using acceptable practical evidence, as approved and authorised by CASA, and documented in SAC's approved Maintenance Training Organisation Exposition (MTOE).
Equivalence of Standard
The RPL and Gap Training pathway does not reduce the competency standard required for the award of the qualification. All learners, regardless of delivery mode, must meet the full requirements of each unit of competency, including performance evidence, knowledge evidence and assessment conditions.
No unit of competency is granted solely on the basis of employment history or documentation without structured assessment and verification.
tuition Fees
$500 on application, balance less credit on commencement
Payment Plan: 50% upfront
with the remaining 50% payable upon completion or within 6 months of the first payment, whichever comes first.
The tuition fee displayed is the maximum total tuition fee for this pathway and assumes that no Credit Transfer is granted. It includes the $500 application payment. After Sigma verifies your prior qualifications and applies any valid Credit Transfer, the remaining balance is confirmed on your final enrolment invoice.
In practice, the vast majority of experienced engineers entering this pathway receive Credit Transfer and therefore pay less than the published maximum. As an indicative example, a holder of the relevant Certificate IV in Aeroskills progressing to a Part 66 licence pathway will typically have the published tuition fee reduced by around one-third, subject to the units accepted for Credit Transfer. The exact reduction depends on the units accepted and cannot be confirmed until Sigma completes its assessment.
Additional charges may apply only where expressly listed in Sigma's current Fees and Refunds Procedure.
Payment: $500 on application. The final balance, after approved Credit Transfer, is payable 50% upfront, with the remaining 50% payable on completion or within 6 months of the first payment, whichever comes first.
Course Duration
Study Load: 8 hours per week
- The RPL & Gap training pathway has a reduced volume of learning versus full-time delivery due to the recognition of experience. Duration is only a guide – students may complete in a shorter or longer timeframe.
- Duration will be shorter if any Credit Transfer is granted.
Before you Apply
- This course is designed for working aircraft maintenance engineers
- This delivery mode requires a minimum of two (2) years of aircraft maintenance experience
- Learners must be currently employed in an aircraft maintenance environment working on operating aircraft
- Learners must be able to provide acceptable evidence for the practical tasks specified in each Unit of Competency
Study Units
What you will learn:
Develop the capability to remove and install pressurised aircraft structural and non-structural components across hangar, workshop, and flight-line tasks, with disciplined control of hazards, tooling, and configuration. Key tasks span using relevant maintenance documentation and aircraft manuals and applying relevant WHS practices, with disciplined sequencing and verification of each step. Theory and application link crew and/or passenger seat restraints, faying surface treatment and fuel tank and pressure, and passenger escape systems to real maintenance decisions and troubleshooting logic. Emphasis is on defensible maintenance decisions—confirming serviceability, managing risk, and leaving a traceable maintenance trail.
- Interpret procedures and specifications for pressurised aircraft structural and non-structural components; confirm applicability, revision status, and any required precautions before work starts.
- Prepare the work area and carry out hands-on tasks on pressurised aircraft structural and non-structural components, using correct tools, test equipment, and contamination control.
- Assess defects and performance on pressurised aircraft structural and non-structural components using appropriate test methods, then confirm correct operation before release.
- Document work performed and test outcomes, and provide a clean technical handover for continuing airworthiness.
What you will learn:
Learn to inspect, repair and maintain aircraft structures under operational maintenance conditions, aligned to approved data and controlled risk management. Hands-on work covers ability to interpret inspection and repair procedures and specifications and a range of rivets using hand, using the right tools and controlled isolation practices. Knowledge areas include construction methods, basic constructional features, and procedures for the fabrication and fitment of metal to support faultfinding and defensible serviceability decisions. Emphasis is on defensible maintenance decisions—confirming serviceability, managing risk, and leaving a traceable maintenance trail.
- Use approved maintenance data (manuals, drawings, standards) for repair and maintain aircraft structures, and confirm configuration, limits, and safety controls.
- Prepare the work area and carry out hands-on tasks on repair and maintain aircraft structures, using correct tools, test equipment, and contamination control.
- Assess defects and performance on repair and maintain aircraft structures using appropriate test methods, then confirm correct operation before release.
- Record results, defects, and rectification actions, and communicate status to support certification-ready handover.
How We Train
How We Undertake Training (RPL & Gap)
Training for students in the RPL and Gap pathway is self-directed online for theory only.
Theory Training
Training for students taking the RPL & Gap training pathway is self-directed online, but supported with engaging learner resources, regular webinars and Q&A sessions, 1:1 tutoring on request, and support from our training team when required.
The following training and resources are provided for each Unit of Competency:
- Audio lecture (available as a podcast feed)^
- Sigma Digital Learner Guide / PDF Learning Materials
- Toolbox 60 webinars (students can attend fortnightly online)
- Live Q&A sessions (students can attend fortnightly online)
- Quarterly check-in
- Tutoring sessions (on request)
Note: Practical training is not offered for this delivery mode. This pathway is designed for engineers with existing experience and supporting aviation industry-standard documentation (e.g. Journal of Industrial Experience, task cards). Students are expected to provide evidence of practical competency, which is assessed via RPL in line with SAC’s Acceptable Practical Evidence Guidelines.
Where practical training is requested, this may be arranged on a fee-for-service basis for groups, either onsite at SAC facilities or offsite at an approved AMO/MRO facility.
^Audiobook rollout in-progress - not all units will include an audiobook at time of enrolment
How We Assess
How We Undertake Assessment (RPL & Gap)
Sigma Aerospace College operates a four-stage RPL & Gap assessment process following successful application and onboarding.
Assessment Phase 1 – Gap Analysis
Once the onboarding process is complete and initial documentation has been provided, SAC undertakes an assessment of prior learning, applicable credit transfer, and any identified knowledge gaps.
At this stage, an invoice is issued for tuition fees (the course fee listed on the website, less any approved credit transfer). Once payment is received:
- The customised learning environment is unlocked
- An initial RPL report (as required by CASA) is issued
This invoice covers all tuition fees, training materials, and any applicable CASA exams.
Assessment Phase 2 – Gap Assessment (Theory) and RPL Evidence Collection (Practical)
Once the customised learning environment is unlocked in the learning management system (aXcelerate), students are presented with:
- Knowledge gap assessments for Units of Competency not granted in full during Phase 1 via RPL or credit transfer
- Practical evidence upload assessments for outstanding Units of Competency
Submitted practical evidence is assessed via RPL against Unit of Competency performance evidence requirements.
Assessment Phase 3 – Competency Conversation
Following completion of gap assessments and submission of sufficient practical evidence (as defined in the Acceptable Practical Evidence Guide), students undertake a clustered competency conversation with an instructor.
- Format: one-on-one discussion
- Duration: approximately 30–60 minutes
- Purpose: final verification of competency
Assessment Phase 4 – CASA Exams
For training products with a CASA outcome, the final stage involves preparation for and completion of invigilated CASA examinations. An administrator will contact the student at the conclusion of Phase 3 to arrange suitable exam times.
Note: Students may apply for recognition of prior learning for any existing practical experience at any time, as long as at the time of Sigma's assessment of that evidence as prior learning (i.e. when uploaded to the relevant capture in the LMS) the evidence meets the terms in the acceptable practical evidence guide, is authentic, sufficient, and meets unit requirements.
