Singapore-based SIA Engineering Company Limited (SIAEC) is expanding its Philippine footprint through local subsidiary SIA Engineering (Philippines) Corporation (SIAEP), with operations at Ninoy Aquino International Airport (NAIA) set to begin by September 2025.
A trusted provider of aircraft maintenance, repair, and overhaul (MRO) services, SIAEP is already operating out of Clark and is majority-owned by the Singapore Airlines Group. The move to NAIA underscores growing investor confidence in the airport’s ongoing upgrades and its potential to become a regional aviation hub.

“This is a big boost for NAIA and Philippine aviation. We welcome SIAEP and look forward to working closely with them to enhance support for airlines operating here,” said Ramon S. Ang, President and CEO of New NAIA Infra Corp. (NNIC).
SIAEP’s presence at NAIA is expected to improve aircraft turnaround times, provide faster technical support, and enhance service reliability for both local and international carriers. It also creates opportunities for job generation, skills development, and knowledge transfer in the country’s aviation sector.
Other major MRO players are reportedly exploring expansion at NAIA as well—an encouraging sign for the country’s aviation ecosystem. Increased competition is likely to lead to better service options and greater operational efficiency for airlines.
“This is part of our broader effort to raise NAIA’s standards—not just as a gateway for travelers, but as a vital hub for the aviation industry,” Ang added.
