What must be done if a visual inspection reveals cracks in the exhaust system?

When a visual inspection uncovers cracks in the exhaust system, it is essential to conduct immediate repairs. The exhaust system plays a critical role in safely directing exhaust gases away from the engine and the aircraft cabin. Cracks can lead to exhaust leaks, which pose serious safety risks, including the potential for carbon monoxide entering the cabin.

Immediate repairs are necessary to ensure the continued safe operation of the aircraft. Addressing the issue promptly mitigates the risk of further damage or failure during flights, which can have severe consequences. In this context, ensuring the integrity of the exhaust system is not just a matter of maintenance, but of airworthiness and passenger safety.

While documenting findings in maintenance logs, conducting carbon monoxide detection tests, or proceeding with flight operations may seem relevant, these actions do not address the root issue of the cracks and could compromise safety if repairs are delayed. For safe operation, making the necessary repairs should always take precedence after identifying such a critical fault.
