Selangor Aero Park 2027: Factory Guide for Aerospace and MRO Suppliers Near KLIA Sepang
Selangor Aero Park phase 1 is due in 2027 with GE Aerospace as anchor tenant. Here is where Tier 2 and Tier 3 aerospace suppliers can find factories near KLIA, and the specs they need.
Key Takeaways
- Selangor Aero Park at KLIA Aeropolis, Sepang, has a first phase of about 200 acres. GE Aerospace holds about 40 ha (100 acres) of it for an engine test cell and MRO facility.
- Phase 1 infrastructure was 48% complete on 20 July 2026 and is due in the first half of 2027. GE's own Sepang facility is expected to finish in 2028 or 2029.
- Park land is allocated directly by Malaysia Airports (MAHB) and the state's MBI, mainly to OEMs and Tier 1 players. For most suppliers, the real property decision is a factory just outside the park.
- The Tier 2 and Tier 3 ring needs precision CNC floors, temperature-controlled inspection rooms, clean assembly areas, surface treatment approvals and parts stores, not generic sheds.
- Look in Sepang, Banting, Dengkil, Nilai and Subang. Start the search 6 to 12 months before a customer contract, because aerospace qualification ties you to one address.
What Selangor Aero Park is, in plain numbers
Selangor Aero Park was launched in June 2025 by Malaysia Airports and Menteri Besar Selangor (Incorporated), or MBI. At launch, MAHB described a park of about 600 acres with a potential GDV of RM2.3b, built in phases: the first 200 acres available immediately, and the remaining 400 acres or so released progressively after 2028. MAHB's later MRO Southeast Asia 2026 release calls it a 445-acre hub for MRO, engine testing, advanced manufacturing and supply chain activities, so expect the total to be quoted at 445 to 600 acres depending on the source.
The most recent official update came from the Selangor State Assembly. In a written answer reported by Media Selangor on 13 August 2026, state executive councillor Ng Sze Han said:
- Phase 1 covers about 81 ha (about 200 acres), of which GE Aerospace has been allocated 40 ha for an aircraft engine MRO facility.
- Earthworks are complete, and infrastructure reached 48% on 20 July 2026, with phase 1 due by the second quarter of 2027. MAHB had earlier pointed to the first quarter.
- The state expects investment of up to RM1b to be realised in 2027.
- Aerospace investment agreements typically take two to three years to finalise. The rest of phase 1 is still under negotiation with MRO, manufacturing, logistics, air cargo and R&D players. Centralised labour quarters are planned.
GE Aerospace has already started building. The Edge reported in June 2026 that GE is building a 500,000 sq ft engine overhaul facility in Sepang, to be completed in 2028 or 2029. A dedicated engine test cell comes first, with the full MRO facility following 6 to 12 months later. GE's existing 300,000 sq ft Subang plant, operating since 1997, employs about 700 people; the Sepang site is expected to add about 300 more.
Why the policy push matters for suppliers
Aerospace is one of the five strategic sectors in Selangor's RS-2 plan for 2026 to 2030, alongside E&E, automotive, the digital economy and the creative economy. According to Bernama in June 2026, Selangor already hosts nearly 70% of Malaysia's aerospace companies and wants to move up the MRO value chain, from airframe maintenance into engines and components, while producing about 22,000 skilled aerospace workers by 2030.
The national numbers explain why engines and components are the focus. Malaysia's aerospace industry earned RM32.5b in 2025, with MRO about 40% of revenue, according to NAICO. Aviation Week, quoted in the same report, expects engines to take 53% of global MRO spending over the next decade and components 21%. An engine shop pulls in machined parts, repairs, tooling, consumables and logistics from nearby firms.

The property reality: the park is not the market, the ring around it is
MAHB's launch statement says the park offers built-to-suit and fully serviced facilities for OEMs and Tier 1 aerospace players, with investment facilitation handled by MAHB and MBI. In other words, plots inside the park are allocated directly by the airport operator and the state, not traded on the open market.
That leaves a much larger group of companies who want to be near KLIA without being inside the fence:
- Precision machining shops for engine, structural and interior parts.
- Composite and bonding workshops.
- Special process firms: plating, painting, heat treatment, NDT.
- Tooling, fixtures and ground support equipment makers.
- Spare parts stockists and aviation logistics firms.
- Avionics and electronics repair shops.
Our reading: most of this demand is for mid-sized detached or semi-detached factories with specific upgrades, not big land. It also comes later than the headlines suggest. GE finishes in 2028 or 2029 and other park deals take two to three years to sign, so supplier site searches will likely peak in 2027 to 2029.
What an aerospace supplier factory needs
| Supplier type | Building must-haves | Power | Approvals and quality checks |
|---|---|---|---|
| Precision CNC machining | Ground-floor slab rated for heavy 5-axis machines, possibly isolated machine foundations; enclosed, air-conditioned CMM room held near the 20°C reference temperature | Medium to high, depends on machine count | Customer usually asks for an AS9100 quality system; first article inspection on each part |
| Composites and bonding | Clean layup room with temperature and humidity control; freezer space for prepreg; clear height and floor load for an autoclave or curing oven | High if you run an autoclave | Material traceability; check fire and fume rules with Bomba and DOE |
| Surface treatment, heat treatment, NDT | Chemical store, fume extraction, effluent treatment, bunded areas | Medium to high (furnaces, rectifiers) | DOE and Bomba approvals; many customers ask for Nadcap on special processes |
| Tooling, fixtures, GSE | Workshop with overhead crane (often 5 to 10 tonnes), wide doors, yard space | Medium | Standard industrial approvals |
| Clean assembly and avionics repair | Sealed, air-conditioned room, ESD-safe flooring, controlled access | Low to medium | Customer and authority approvals for repair work |
| Spare parts and aviation logistics | Clean racked warehouse, security, fast access to KLIA cargo | Low | Check bonded or licensed warehouse options with Royal Malaysian Customs |
Two items sink most shortlists. The first is the floor: check the slab under your heaviest machine with our floor loading calculator and a structural engineer before you sign. The second is power: a machining or furnace line can outgrow an older factory's TNB supply, and upgrades take time. If you need a unit that already has the amps in place, including ones that are not publicly advertised, ask us for high-power factories in Selangor.
The metal fabrication factory requirements page is a useful baseline; aerospace adds the controlled inspection room, cleanliness and traceability.
Where to look: the supplier ring around KLIA and Subang
| Area | Why it fits | Watch out for |
|---|---|---|
| Sepang | Closest to KLIA Aeropolis and the park; mix of detached factories and land | Limited stock of high-spec units; check flood history on low-lying lots |
| Banting | Larger detached factories and land parcels; reachable from KLIA by road | Some estates are older, so check slab and power |
| Dengkil | Between Cyberjaya and KLIA, with good highway access | Competes with data centre buyers for land, such as Mah Sing's 78.8-acre Dengkil sale at about RM180 psf |
| Nilai (Negeri Sembilan) | Close to KLIA across the state border; established industrial estates | Different state and local authority approvals |
| Cyberjaya fringe | Fits light electronics and avionics work | Very few factories; most land is data centre or commercial |
| Subang | Malaysia's established MRO cluster at Subang Airport | Higher rents, older stock, tight supply |
Start with factories for sale in Sepang for the closest options, then widen to factories for rent in Banting and Nilai factories for rent if you need more space for the budget.
Do not ignore Subang, where most of today's MRO work sits. Collins Aerospace has a US$63m expanded MRO facility in Subang Aerotech Park, and Base Maintenance Malaysia, set up by SIA Engineering, has opened hangars at Subang Airport (The Edge). In July 2026, MAHB and Mitsui Fudosan broke ground on an RM80m MRO logistics complex at Subang Aerotech Park, with about 254,420 sq ft of ready-built space for aviation and logistics operators, due in the third quarter of 2027. Suppliers serving existing Subang customers may be better off in Subang factories for rent and moving south later. To filter by power, height and floor load across all these areas at once, use find a factory by specs.
Timeline to plan around
| Date | Milestone | What it means for supplier property |
|---|---|---|
| June 2025 | Park launched; GE Aerospace named launch tenant | Long-range planning starts |
| 20 July 2026 | Phase 1 infrastructure 48% complete | Park is real, but not yet open |
| Q1 to Q2 2027 | Phase 1 infrastructure complete | Second-round tenants can start building |
| 2027 | State target of up to RM1b realised investment | New supplier names start to appear |
| Q3 2027 | Subang MRO logistics complex complete | More ready-built aviation space in Subang |
| 2028 to 2029 | GE Sepang facility complete (test cell first) | Peak period for supplier site searches |
| After 2028 | Remaining park land (about 400 acres) released | Second wave of anchor tenants |
| 2030 | RS-2 period ends; Aerospace Blueprint target of RM55.2b revenue | State and national targets reviewed |
Checklist before you sign a supplier factory near KLIA
- Confirm your customer's quality and special process requirements first. Ask which certifications they need (AS9100, Nadcap, their own source approval) and how long their facility audit takes.
- Match the lease to the qualification timeline. Moving a qualified line often means repeating first article inspection and customer audits.
- Check the slab and foundations for your heaviest machine, and whether isolated foundations can be cut in.
- Check the TNB supply in amps and how much spare capacity remains, not just the number on the meter board.
- Plan the controlled rooms. Check that an enclosed CMM or clean assembly room fits without major structural work.
- Clear approvals early. For plating, painting, heat treatment or chemicals, check with DOE, Bomba and the local council whether the lot can be approved for that use.
- Test the commute. Skilled technicians are scarce; a site your engineers will not drive to is a hiring problem.
- Line up the timing. Start looking 6 to 12 months before the contract; good high-spec units near KLIA do not stay empty long.
FAQ
Can my company buy or rent land inside Selangor Aero Park?
Park land is allocated by Malaysia Airports and MBI, with built-to-suit facilities aimed at OEMs and Tier 1 players; at that level, talk to them directly. Most Tier 2 and Tier 3 suppliers will move faster with a factory in the surrounding areas.
When will Selangor Aero Park be ready?
Phase 1 infrastructure was 48% complete on 20 July 2026, with completion targeted for the first half of 2027. The state assembly answer in August 2026 gave the second quarter. GE Aerospace's own Sepang engine facility is expected to finish in 2028 or 2029.
What certifications do aerospace suppliers usually need?
Most aerospace customers expect an AS9100 quality management system, and many ask for Nadcap accreditation on special processes such as heat treatment, plating and non-destructive testing. Requirements differ by customer and part, so confirm them in writing before you choose a building.
Which areas are best for an aerospace supplier factory near KLIA?
Sepang is the closest. Banting, Dengkil and Nilai offer more space and choice within reach of KLIA. Subang remains the base of today's MRO cluster, so suppliers with Subang customers often stay or run two sites during the transition.
How much power does an aerospace machining shop need?
It depends on your machine list. Five-axis machines, compressors, air-conditioned inspection rooms and any furnaces or autoclaves add up quickly, so total the connected load, add room for growth, and compare it with each unit's TNB supply rating.
Is it better to move now or wait until the park opens?
With a customer award or firm pipeline, securing a unit now avoids competing for the few high-spec factories near KLIA in 2027 to 2029. If your work depends on unsigned deals, renting with an option to expand is lower risk, since aerospace agreements typically take two to three years.
