The Aircraft Engine Cylinder Report

Cracks in your aircraft's cylinders will lead to problems in-flight. Somewhat fortunately, your engine will alert you with roughness, and you will have time to land. But your cylinders are crucial - keep them clean and sturdy, or expect malfunction. Here are some recent FAA Service Difficulty Reports that highlight the issue.

Key Takeaways:

• Aircraft experienced various engine cylinder failures, including separations, cracks, and low compression, often detected during flight or routine inspections.
• Cylinder cracks commonly occurred at spark plug holes, injector ports, or near exhaust ports, with some attributed to thin metal around intake valve areas.
• Cylinder manufacturers ECI and Superior were frequently implicated, with Superior cylinders specifically noted for a history of over 250 failures and manufacturing defects.
