Borescope inspection for aeroderivative gas turbines powering data centers
Data centers waiting years for a grid connection have started generating their own power, and the fastest way to add tens of megawatts is an aeroderivative gas turbine — a jet engine core packaged for stationary power. Industry reporting in 2026 describes orders for these units from data-center developers rising by an order of magnitude, GE Vernova's LM2500 and LM6000 as the default choices, and FTAI Power converting retired CFM56 engines into 25 MW turbines with production starting in 2026. Every one of those cores needs the inspection discipline it had on an aircraft.

Why the inspection matters more at base load
An airline engine accumulates a few thousand hours a year. A turbine running base load behind a data center can run most of the hours in the year, so inspection intervals set in operating hours arrive in months, not years. The failure modes are familiar — thermal barrier coating spallation, combustor cracking, turbine blade erosion, cooling-hole blockage, compressor fouling — but they arrive faster, and an unplanned outage means a data hall on backup power.
What a borescope inspection of an aeroderivative unit covers
The compressor stages for fouling, erosion and foreign object damage; the combustor for cracks, burn-through and deposits; the high-pressure turbine nozzles and blades for coating loss, cracks and erosion; and the power turbine. The unit is shut down and cooled, the ports opened, and each stage recorded on video with findings sized against the manufacturer's limits.
What is different from an aircraft
Natural gas fuel changes the combustor deposits; the package environment changes compressor fouling; starts matter but flight cycles do not. The inspection method, the camera and the judgement are the same, which is why aviation borescope inspectors are the people being asked to do this work.
Why independent documentation matters
Financiers, insurers and the data-center operator all want to know the condition of a 25 MW asset between major overhauls, from someone who is not selling the overhaul. An independent inspection report with video, measurements and limits is that record.
What to ask an inspector
Which cores they are qualified on; whether they inspect to the OEM manual for the industrial variant; what the report contains; how quickly they can be on site when the unit has a planned outage window.
FAQ
- How often does an aeroderivative turbine need a borescope inspection?
- At the hours-based interval in the manufacturer's maintenance manual for the unit, and after any exceedance or abnormal trend. At base load those intervals come around quickly.
- Can the inspection be done without shutting down?
- No. The unit must be shut down and cooled, so inspections are planned into low-load or maintenance windows.
- Are aircraft engine borescope inspectors qualified for industrial units?
- The hardware and the method are the same; the qualification is per unit and per manual. Ask the provider which cores they cover before booking.
