Revenue model
- MRO Services (Maintenance, Repair & Overhaul): Provides commercial line maintenance, base maintenance, aircraft component overhaul, and parts supply. Revenue is earned through billable maintenance events, hourly labour, and parts sales. Targets large airlines, regional operators, and individual aircraft owners. Services include line maintenance at Adelaide and Tamworth, GA MRO in NSW, piston engine overhaul, propeller overhaul, turbine engine maintenance, avionics, instrument calibration, and engine/component exchange.
- Engine & Component Overhaul: Suncoast Aero Engines (now incorporated into Sigma MRO) overhauls Lycoming and Continental piston engines, propellers, fuel systems, magnetos, turbochargers, and governors. Revenue is generated through flat-rate or quote-based overhaul fees plus parts markup. Exchange engine and component inventory enables rapid turnaround, generating transactional revenue from swap/out/exchange arrangements.
- Aviation Workforce Solutions: Direct recruitment fees, contingent labour bill rates, managed HR/outsourced payroll services, and OHLA-sponsored international placement fees. Revenue scales with workforce volume and contract duration. Try Before You Hire creates a pathway from short-term contingent engagement to permanent placement fees.
- Aircraft Engineer Training & Licensing: Sigma Aerospace College charges fees for apprenticeship programs, Certificate IV and Diploma of Aeroskills, CASA Part 66 licensing pathways, exclusion removals, type training, RPL assessments, and requalification courses. Programs serve both new entrants and working engineers seeking career advancement.

Sigma Aerospace competitors and assessment
Company assessmentBroad incumbents
- Lufthansa Technik: World's largest independent MRO provider serving commercial airlines, business aviation, and defence. Represents the global incumbent benchmark against which Sigma's integrated Australian model must compete for multi-region and international fleet contracts.
- AAR Corp: US-listed global aviation services provider offering MRO, parts supply, and integrated solutions across commercial and defence markets. Comparable as a broad incumbent MRO platform competing for airline and defence sustainment contracts at larger scale than Sigma.
- Honeywell Aerospace: Engine OEM and authorised service centre network for TPE331 and other turbine platforms. Sigma is a Honeywell TPE331 Authorised Service Centre but Honeywell's broader global service network competes for higher-volume engine MRO work outside Sigma's Australian footprint.
- Pratt & Whitney Canada: Engine OEM with global authorised service network covering PT6A and PW100 series engines that Sigma services. Comparable on the turbine engine MRO axis but operates as an OEM-led global network rather than an independent regional specialist.
- BAE Systems Australia: Australian defence prime operating sustainment and MRO for Hawk, F-35, and other ADF platforms. Functions both as a Sigma customer (defence workforce) and a broad incumbent competing for in-house engineering capacity and large-scale sustainment contracts.
Direct peers
- Vector Aerospace: Engine MRO and component repair specialist (now part of StandardAero) with strong helicopter and regional turboprop engine services. Comparable to Sigma's Honeywell TPE331 authorised service centre and PT6A HSI/GBI/Overhaul capabilities.
- StandardAero: Global independent MRO provider with engine services, component repair, and avionics capabilities across business aviation, commercial, and helicopter platforms. Directly comparable to Sigma's engine and component overhaul operations, though at substantially larger scale.
- TAE Aerospace: Australian-headquartered engine MRO and aerospace services provider with similar scope across military and commercial platforms. Operates engine overhaul, component repair, and workforce solutions across the Asia-Pacific, overlapping directly with Sigma's engine MRO and defence recruitment footprint.
- Airflite: Western Australia-based aviation services group offering line maintenance, base maintenance, component overhaul, and FBO services. Comparable as an Australian MRO competitor serving regional airlines, charter operators, and general aviation, with similar CASA Part 145 certifications.
- Aviation Australia: CASA Part 147 approved Maintenance Training Organisation and aviation training provider offering Part 66 licensing, type training, and apprenticeship pathways. Direct peer to Sigma Aerospace College on the training and licensing side of Sigma's integrated model.
