You are conducting a borescope inspection of the compressor section of a LM2500 gas turbine. In stage four, you see a slight tilt to one blade and the blade platform is raised higher than the other blades. What could be a cause of this condition and what would be your course of action?

Correct Answer: Option A — Condition could be the result of blade root failure. Engine should be taken out of service until condition can be evaluated.

A tilted blade with a raised platform indicates a failure of the blade root or its retention mechanism. This is a critical structural integrity issue. Per manufacturer technical manuals and USCG safety guidelines, the engine must be secured immediately to prevent catastrophic blade liberation and severe internal engine damage.
