The creation of what issue could lead to excessive chips in the engine of the TH-73A?

• A. Fuel contamination
• B. Internal wear and tear
• C. Faulty electronics
• D. Consistent maintenance

Answer: (B)

Internal wear and tear can lead to excessive chips in the engine of the TH-73A because it refers to the gradual deterioration of engine components due to friction, heat, and normal operational stresses over time. As parts wear down, small metal fragments or chips can be created as a byproduct of these processes. These chips can circulate in the lubrication system and lead to further damage, making it crucial to monitor wear rates and address any worn components promptly to maintain engine integrity.

While fuel contamination can certainly cause issues within the engine, it typically results in performance problems rather than the specific creation of metal chips. Faulty electronics could lead to operational malfunctions, but they would not directly cause the physical breakdown of engine components leading to chips. On the other hand, consistent maintenance is aimed at preventing wear and tear and ensuring that all systems function as intended, which counters the problem rather than creates it.
