ST Aerospace Systems

Through our avionics and mechanical centres in Singapore, we provide aircraft component repair and overhaul services for a wide range of commercial and military aircraft.

Leading Edge Facilities for Aircraft Component Repair and Overhaul

From our humble beginnings in 1969, ST Aerospace Systems has grown to the point where today, we provide repair and overhaul services for over 8,000 mechanical and avionics component types. We service global commercial and military customers from our avionics and mechanical centres which together occupy some 18,000 m2 of space in Singapore.

Our avionics centre comprises five modern workshops with air-conditioning, including a Class 10K clean room. The centre provides services for flight management and display system, radar, radio communication and navigation equipment, electromechanical and electronic instruments, autopilot and navigation systems and more.

Our mechanical centre has five modern workshops, supporting systems that include hydraulics, landing gear, propeller, helidynamic and transmission, piston engine and more.

A comprehensive range of in-house capabilities support our avionics and mechanical centres, which includes a computerised metrology centre, non-destructive inspection, rework and machining, static and dynamic balancing and hydrostatic testing for bottles and cylinders.

Focused on Quality and Reliability
Our management systems are developed in compliance with international standards and requirements and we emphasise quality workmanship, which is evident in the approvals we have attained. We are a Part 145 repair station approved by many airworthiness authorities worldwide, including those from Singapore, the United States, Europe, China and Japan.
