🔍 Key Concepts

• Borescope inspection limitations when viewing rotating machinery like compressor blades • Typical characteristics of airfoil and tip cracks on compressor blades • Effect of operator technique vs. defect geometry on detectability

💭 Think About

• Think about what makes a crack visually hard to see, even with good equipment and proper technique. • Ask yourself which options describe conditions that are inherently common to airfoil and tip cracks themselves, not just possible procedural errors. • Consider whether all the listed factors must be true at the same time, or whether one of them is the fundamental, built‑in reason these cracks are hard to spot.

✅ Before You Answer

• Check which choice best matches the physical nature of compressor blade cracks (how they look and how deep they are). • Verify whether borescope deterioration is a normal, expected reason for poor detection, or a separate maintenance issue. • Confirm whether rotor speed during inspection is actually a typical limiting factor, given that inspections are usually done with the rotor slowly indexed or stationary.

Question 1 of 20

When conducting a borescope inspection of the compressor, why can airfoil and tip cracks be difficult to detect?

Borescope optics have deteriorated.

Rotating the rotor too fast.

The cracks are generally tight and shallow in depth.

All of the above.
