MAB Engineering Services (MAB Engineering) has doubled its maintenance capacity at Sultan Abdul Aziz Shah Airport (SZB) following the successful commissioning of its new Hangar 4 airframe maintenance facility.
The expansion follows a 15-year lease agreement with Impeccable Vintage Properties Sdn Bhd (IVP), a wholly owned subsidiary of Khazanah Nasional Bhd, and marks the next step in strengthening MAB Engineering’s position as a regional MRO provider.
More than a simple relocation from Hangar 1, the move to Hangar 4 forms part of Malaysia Aviation Group’s (MAG) Long-Term Business Plan 3.0, launched in December 2025 to create a more efficient, resilient and future-ready engineering operation.
Captain Nasaruddin A. Bakar, President and Group Chief Executive Officer of MAG, said: “The successful commissioning of Hangar 4 marks a significant milestone in strengthening our engineering and maintenance capabilities as part of MAG’s long-term growth strategy. 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 new facility significantly expands MAB Engineering’s ability to support both Malaysia Airlines and Firefly fleets, while also increasing capacity for third-party MRO customers. Around half of the hangar’s capacity has been allocated to Malaysia Airlines and Firefly maintenance requirements, with the remaining capacity dedicated to external commercial work as the company seeks to strengthen its position in the regional MRO market.
Previously, Hangar 1 was limited to just two maintenance lines due to structural constraints. Hangar 4 now enables four simultaneous maintenance lines, including one wide-body line for Airbus A330-200 and A330-300 aircraft, one narrow-body line for Boeing 737-800 and Boeing 737-8 aircraft and two turboprop lines for ATR72 aircraft.
