MAB Engineering Services, a subsidiary of Malaysia Aviation Group, has doubled its aircraft maintenance capacity at Sultan Abdul Aziz Shah Airport in Subang following the commissioning of Hangar 4.
The facility became operational on May 7, 2026, under a 15-year lease agreement with Impeccable Vintage Properties, a subsidiary of Khazanah Nasional Bhd. Previously based in Hangar 1, which supported only two maintenance lines, MAB Engineering has relocated to the larger Hangar 4.
Hangar 4 accommodates four simultaneous maintenance lines: one for widebody A330-200 and A330-300 aircraft, one for narrowbody Boeing 737-800 and 737-8 jets, and two for ATR72 turboprops. About 50 percent of the capacity serves Malaysia Airlines and Firefly fleets, with the remainder available for third-party customers.
The expansion supports MAG’s long-term business plan and improves operational efficiency through better workflow and resource utilization across mixed fleet types, according to company statements.
