Key Takeaways:

Aircraft exhaust systems are prone to various failures including cracks, holes (often due to failed welds), and deterioration of ball joints, affecting components like mufflers, risers, and tailpipes.
These failures can occur across a wide range of operating hours, from very low times (e.g., 100 hours) to thousands of hours.
Exhaust issues are frequently detected during routine inspections, through carbon monoxide warnings in the cockpit, or via symptoms like engine roughness, necessitating immediate component replacement.
