MAB Engineering doubles MRO capacity at Subang with new hangar launch

MAB Engineering has doubled its maintenance capacity at Kuala Lumpur’s Sultan Abdul Aziz Shah Airport (SZB) following the commissioning of its new Hangar 4 airframe maintenance facility.

The MRO provider, a subsidiary of Malaysia Aviation Group (MAG), said the expansion forms part of a 15-year lease agreement with Impeccable Vintage Properties Sdn Bhd (IVP), a wholly-owned subsidiary of Khazanah Nasional Bhd.

According to the company, the new facility marks a strategic expansion under MAG’s Long-Term Business Plan 3.0, launched in December 2025, aimed at creating a more efficient and resilient maintenance operation while strengthening Malaysia’s position as a regional aviation hub.

Captain Nasaruddin A. Bakar, president and group chief executive of MAG, said: “This expansion not only doubles our maintenance capacity at Subang, but also enhances our ability to serve both MAG airlines and international customers more effectively.

“As demand for high-quality MRO services continues to grow across the region, Hangar 4 positions us to compete more strongly, support Malaysia’s ambition as a regional aviation hub, and deliver greater long-term value to the Group and our customers.”

The additional capacity will support both Malaysia Airlines and Firefly fleets, while also expanding third-party MRO opportunities. MAB Engineering said approximately half of the facility’s capacity is allocated to internal fleet requirements, with the remaining 50% dedicated to external customers.

Previously limited by Hangar 1, which could support only two maintenance lines, the new Hangar 4 facility enables simultaneous operation of four lines. This includes one widebody line for Airbus A330-200 and A330-300 aircraft, one narrowbody line for Boeing 737-800 and Boeing 737-8 aircraft, and two ATR72 turboprop lines.

MAB Engineering added that the move to Hangar 4 improves operational efficiency through a more structured maintenance environment, supporting better workflow planning, greater flexibility across mixed fleet types, and improved resource utilisation.

The company also said the expansion reflects its continued focus on workforce development and creating a stronger operational environment for employees.
