🔍 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.
