What can prevent an aircraft engine from achieving its normal service life?

  1. Excessive flying hours

  2. Corrosion in and around the cylinders

  3. Poor fuel quality

  4. Neglecting routine maintenance

The correct answer is: Corrosion in and around the cylinders

Corrosion in and around the cylinders can lead to significant damage and reduce the service life of an aircraft engine. Corrosion occurs when moisture, salt, and other contaminants interact with the metal surfaces, causing deterioration over time. In the case of engine cylinders, this can affect the structural integrity and performance of the engine components, potentially leading to failure or the need for early replacement. While other factors, such as excessive flying hours, poor fuel quality, and neglecting routine maintenance, can also contribute to the overall health and longevity of an aircraft engine, corrosion specifically targets the critical components that directly influence engine reliability and efficiency. Addressing corrosion is essential in maintaining engine performance and extending its operational lifespan.
