Not performing compressor field cleaning can lead to which consequences?

• A. Increased fuel efficiency
• B. Slower accelerations, high EGT, and potential engine failures and corrosion
• C. Improved engine reliability
• D. No impact

Answer: (B)

Not cleaning the compressor field allows deposits and debris to build up on blades and in passages, disrupting smooth, high-velocity airflow into the compressor. That loss of clean flow reduces the compressor’s efficiency and the engine’s ability to deliver the required air mass, so the fuel control has to work harder to reach the desired power. The result is higher exhaust gas temperature as more fuel is burned to compensate for the reduced air, and slower accelerations because the engine cannot respond quickly with enough air. Over time, the combination of degraded airflow, higher temperatures, and mechanical stress raises the risk of compressor surge or stall and can propagate damage through the engine, including corrosion and other failures in exposed components. This is why neglecting compressor cleaning tends to produce slower performance, hotter exhaust, and potential reliability and durability problems. Other options imply benefits or no impact, which contradicts the effects of restricted airflow and increased heat.
