Aerospace Component Engineering Services Pte Ltd (ACE Services) is a Singapore-based aerospace MRO provider specializing in the maintenance, repair, and overhaul of hydromechanical components for commercial aircraft. The company operates as a joint venture between Parker Aerospace, a global leader in hydraulic flight control actuation systems, and SIA Engineering Company, one of Asia's largest MRO organizations. ACE Services focuses on flight control actuators, power control units, thrust reverser and landing gear actuators, valves, and pumps across commercial aircraft platforms including Boeing 737/747/777/787, Airbus A320/A330/A350, De Havilland Q400, and Embraer E-Jet 170/190. It is designated as a Parker Centre of Excellence, an authorized warranty repair centre for Parker products, and a Boeing-approved repair facility, with additional repair capabilities covering components from Shimadzu, Collins, Woodward, Eaton, Crane, and Safran.

The company's facility at 45 Changi North Crescent is equipped with automated and dedicated test stands, non-destructive testing capability (FPI and MPI), data acquisition systems, and a digitalized documentation system. ACE Services holds certifications from major global aviation authorities and is regularly CASE-audited. It serves as the designated hydraulic repair centre for the Singapore Airlines Group and supports over 80 international airlines and MRO customers across the Asia-Pacific region.

ACE Services generates revenue through three streams: transaction-based MRO services billed per component or repair event, Cost-Per-Hour (CPH) programs priced on usage, and Repair Management services offering outsourced maintenance oversight. Pricing is custom-quoted per engagement. The company employs between 11 and 50 staff and operates as a strategic subsidiary within SIA Engineering Company's supporting network, with go-to-market executed through direct enterprise engagement with airline procurement and maintenance departments, leveraging account managers and field service engineers from both Parker Aerospace and SIAEC.
