Key Takeaways:

Aircraft exhaust systems commonly experience failures such as cracks, holes (often due to failed welds), and deterioration or blockage of components like risers, mufflers, and ball joints.
These failures pose significant safety risks, frequently leading to carbon monoxide warnings in the cockpit and requiring immediate maintenance actions.
Exhaust system issues were observed across a broad spectrum of operating hours, from relatively low (e.g., 100-130 hours) to high, highlighting the need for continuous vigilance during inspections.
