Key Takeaways:

Aircraft exhaust systems are prone to various integrity failures, including cracks, breaks, disengagement, separation, and manufacturing/installation defects.
These failures frequently lead to significant operational issues such as loss of engine boost or manifold pressure, severe heat damage to adjacent components, and exhaust gases entering the cabin.
Exhaust system malfunctions are reported across diverse aircraft models, affecting components like wastegates, exhaust pipes, and crossover tubes, sometimes at relatively low operating hours.
