Maintenance, repair and overhaul of aircraft, engines and components.
Scope covers line and base maintenance, engine and module overhaul, component repair, and composite structure repair, performed under regulator approval. Buyers select providers by airframe or engine-type authorisation, regulatory approval, and turnaround time. The companies on the record holding this capability are collected on the Singapore Industry Index’s list of Leading aerospace companies in Singapore.
A buyer or engine OEM evaluating an aircraft-engine MRO partner starts with engine platform coverage — which families a shop is tooled and licensed to touch: Rolls-Royce Trent (500/700/800/900/1000/7000/XWB) and RB211; CFM56 and the new-generation CFM LEAP; GE90/GEnx/GE9X/CF6; IAE V2500; Pratt & Whitney PW4000/PW2000 and the geared GTF (PW1100G); plus regional turboprop and turboshaft lines such as PT6 and PW100/127. The next questions are depth of work — full engine overhaul and module repair versus piece-part and component repair (combustors, fuel nozzles, HPC drums, turbine blades and vanes) — and whether the shop runs its own engine test cells, the gating asset that lets an overhauled engine be certified and returned to service. Credibility rests on certifications and OEM authorisations: EASA/FAA Part 145 approval plus OEM-licensed status. Finally buyers weigh turnaround time, coatings and blade-repair depth (EB-PVD, HVOF thermal spray, cathodic-arc and cubic-boron-nitride processes that extend hot-section life), and commercial models such as maintenance-by-the-hour and quick-turn shop visits.
Singapore is one of the world's pre-eminent engine-MRO hubs, anchored by Seletar Aerospace Park, the Loyang engine cluster and Changi North. Its defining feature is a dense web of OEM-owned MRO joint ventures sitting beside strong independents. Rolls-Royce runs its Seletar campus and, with SIA Engineering, the Trent overhaul giant SAESL. Pratt & Whitney operates its Singapore Engine Center through Eagle Services Asia and a family of component and coating joint ventures. GE Aerospace concentrates a majority of its global component-repair volume across three Singapore plants. The independents — SIA Engineering Company and ST Engineering — provide engine services, LEAP overhaul and component MRO at scale, and Safran has agreed a Singapore LEAP-overhaul JV with SIAEC. Together these make Singapore a full-stack engine-MRO ecosystem: overhaul, module and component repair, test, and specialist coatings.

Listed alphabetically. Order does not indicate ranking.
A combustor, fuel-nozzle and tube repair-and-overhaul specialist covering PW4000, PW2000, V2500 and CFM56 engines: complete overhaul, repair and modification of combustion chambers, fuel nozzles, turbine-stage assemblies, ducting and manifolds. A Pratt & Whitney / SIA Engineering joint venture, based at Seletar Aerospace View.
Pratt & Whitney's Singapore Engine Center, a joint venture owned 51% by Pratt & Whitney and 49% by SIA Engineering. It overhauls PW4000 and GE90 engines and has inducted the new-generation geared turbofan (PW1100G), with deep in-house repair including full PW4000 high-pressure-compressor drum and sync-ring repair. The site has passed a 7,600-engine overhaul milestone.
Handles more than 60% of GE Aerospace's global repair volume from three Singapore plants employing over 2,400 people: Plant 23 and Plant 62 at Loyang repair turbine blades, nozzles, combustors, compressor blades and vanes; Plant 46 at Seletar produces high-pressure compressor components and is expanding into module repair. Covers GE90, GE9X, GEnx, CF6, CFM56, CF34 and CFM LEAP and industrial LM2500/LM6000, and pioneered additive repair of jet-engine components.
Beyond its Eagle Services Asia engine centre and component and coating joint ventures, Pratt & Whitney has ramped geared-turbofan component aftermarket repair in Singapore, and Pratt & Whitney Canada has launched full overhaul for the PT6C-67C turboshaft (Leonardo AW139) with a new modular test cell and extended PW100/PW127XT turboprop overhaul (ATR 42/72) — a cornerstone of its Asia-Pacific network. Its Seletar advanced-manufacturing plant also produces critical GTF engine components — hybrid metallic fan blades and high-pressure turbine discs.
Rolls-Royce's Asia-Pacific manufacturing and support hub, a 154,000 sqm campus at Seletar Aerospace Park. Home of Fan Blade Singapore, the global lead facility for the patented hollow titanium wide-chord fan blade, plus an engine test facility, a regional training centre and the Civil Aerospace Asia-Pacific customer-service team. The OEM half of the SAESL Trent-overhaul joint venture.
A forthcoming joint venture, Safran Aircraft Engines 51% and SIA Engineering 49%, building a state-of-the-art LEAP-1A/1B overhaul facility on SIAEC's existing engine-services site at Changi North, expanding shop-visit capacity beyond today's quick-turn work.
Singapore's largest home-grown MRO group and the anchor shareholder across the engine-joint-venture network (SAESL, Eagle Services Asia, Turbine Coating Services, Component Aerospace Singapore). Its own Engine Services line covers change, test, preservation, defect rectification, boroscope work and Quick Turn shop visits across GE (GE90/GEnx/CF6), CFMI (CFM56/LEAP), IAE V2500, Rolls-Royce Trent/RB211 and P&W PW2000/4000, with test cells for Trent, GP7200, LEAP-1A, PW4000 and GE90 at Changi.
The world's largest Rolls-Royce Trent engine-overhaul operation, a 50/50 joint venture of Rolls-Royce and SIA Engineering. It uniquely supports all Trent variants (500, 700, 800, 900, 1000, XWB), overhauls over 300 Trent engines a year with a workforce above 1,000, runs a dedicated engine test facility, and performs component repair on over 80% of the engine through five accredited Centres of Excellence. The flagship engine-MRO name in Singapore.
A major independent MRO and Singapore's largest home-grown aerospace group. The first independent provider in Asia to join CFM's authorised LEAP network as a Premier MRO; it services CFM LEAP-1A/1B, CFM56-5B/7B and military and turboshaft lines. In-house capabilities include automated fan-abradable repair, HVOF thermal-spray coating, high-pressure water-jet cleaning and precision grinding, alongside broad component MRO for more than twenty OEMs. Its Aerostructures & Systems arm also designs and builds nacelle systems, thrust reversers, cowls and specialised aerostructures.
