Company brief
SIA Engineering Company (SIAEC) is a Singapore-based aircraft maintenance, repair, and overhaul organisation listed on the Singapore Exchange (SGX) and majority-owned by Singapore Airlines Group. Incorporated on 1 January 1992 (Singapore Co. Reg No.: 198201025C) and headquartered at 31 Airline Road, Singapore 819831 adjacent to Singapore Changi Airport, SIAEC is one of Asia-Pacific's largest and most respected MRO providers, serving a diverse portfolio of airline customers across its comprehensive suite of maintenance services.
SIAEC's service capabilities span base maintenance for heavy scheduled checks on commercial aircraft, line maintenance and technical handling for quick-turn and transit checks, fleet management programmes, cabin solutions including full turnkey cabin retrofit and reconfiguration, engine services encompassing a comprehensive portfolio of engine value-added work, and component maintenance and overhaul covering avionics, hydraulics, and structural components through in-house workshops. The company also provides aircraft transition services, technical training through its Training Academy, and radome inspection, testing, and repair. In March 2026, SIAEC signed agreements with Arport Aircraft Maintenance and Engineering (Fujian) to form an MRO joint venture in Fujian, China, and in March 2026 its Base Maintenance Malaysia operation celebrated its first cohort of homegrown technicians.
SIAEC has established an extensive joint venture and subsidiary network across Asia and beyond, enabling international service capability from strategic hub locations. The company holds regulatory approvals from multiple civil aviation authorities including the Civil Aviation Authority of Singapore (CAAS) and EASA, and its quality systems are underpinned by the relevant Aviation Authority-approved maintenance organisation certifications. SIAEC participates in major industry events including MRO Greater China 2026 (Beijing, May 2026), reflecting its active positioning in the Asian MRO market.
