THAI Technical Department  is rapidly gaining recognition as one of Asia's experts in overhauling General Electric Engines. THAI relies on GE engines to power its fleet of more than 60 aircraft.

We were the first Asian airline to use high-thrust CF6-50 engines, and have developed the technical competence to carry out most repair. We were also the launch customer for the A300-600 with CF6-80C2 engines and can conduct repairs up to level  of overhaul

In our engine repair shop we strip an engine to its smallest components. We then utilise the latest Digital Electronic Automation three-dimensional measuring equipment to conduct diagnostic tests

THAI Technical Department  also employ the more traditional non-destructive testing methods including ultrasonic, eddy current, dyepenetrant (THAI Technical Department  was the first facility in Southeast Asia to install an automatic carousel), X-ray, and magnetic particle equipment.

In our workshops,we chemicall and mechanically clean, repair, and/or create all parts, or replace them from our inventory of 200,000  line items. We can plasma coat metals using an advanced model molten spray robot. We use a Macromet II to test hardness of metal component surfaces. Among our precision equipment is the biggest Vertical Turret Lathe ever made. The one-storey tall lathe can cut and trim metal pieces to a maximum diameter of 2.6 metres.

On site is a test cell capable of generating a maximum thrust of 150,000 pounds. This modern facility enables us to run General Electric and Pratt & Whitney and RR ( Rolls-Royce) engines to full power while executing computer control checks using programmes developed by engine manufacturers. In it, we test FADEC engines and replace their components.

There is also a small shaft cell to test gas turbine engines using computerised test equipment.
