LM6000 vs LM2500: inspection intervals and what a hot section inspection finds
Industry reporting in 2026 puts the LM2500 family above 2,700 units worldwide and the LM6000 above 1,200, with both being ordered by the gigawatt for data-center power. Both trace to GE's CF6 aircraft-engine family, and both are inspected with a borescope.

The two machines
The LM2500 is the smaller, long-established unit used in ships, oil and gas and power generation; the LM6000 is larger and derived from the CF6-80C2 core. Each has its own maintenance manual, port map and limits, set by the manufacturer for the industrial variant.
How intervals are set
In operating hours and starts, by the manufacturer's manual and the operator's program; indicative figures reported by the industry put a hot section inspection in the tens of thousands of hours and a major overhaul at roughly double that, but the manual for the specific unit and its operating profile is what counts. A base-load data-center unit reaches those hours far sooner than a peaking unit.
What a hot section inspection finds
Combustor liner cracking and deposits that vary with the fuel; turbine nozzle and blade coating loss, cracking and erosion; cooling-hole blockage; and, on the compressor side, fouling and erosion that track the package's air filtration. Findings are sized against the unit's limits and reported with video.
What to ask a provider
Which units they are qualified on; which manual they inspect to; what the report contains; how they fit into a planned outage window.
