Key Takeaways:

Aircraft exhaust systems, especially in turbocharged models, are frequently experiencing various failures, including cracks, leaks, defective welds, disengagement, and severe pitting.
These failures commonly occur at high-stress points such as wastegate attachment flanges, collector tubes, and turbocharger transition pipes, likely due to extreme heat and pressure.
Problems are discovered during routine maintenance like annual inspections and oil changes, but can also manifest as in-flight incidents such as loss of pressurization or decreased manifold pressure.
