What should be done if cooling fin damage is discovered?

When cooling fin damage is discovered, the appropriate action is to refer to the manufacturer's repair limitations. This is crucial because manufacturers provide specific guidelines regarding acceptable damage levels, repair methods, and any necessary inspections to ensure the integrity and functionality of the engine components.

Cooling fins play an essential role in dissipating heat from the engine, and even minor damage can affect performance and reliability. Following the manufacturer's recommendations ensures that repairs are made correctly and that the engine operates safely and efficiently.

Ignoring minor damage can lead to more significant issues over time, such as overheating or engine failure, which compromises safety. Replacing the entire cylinder is a drastic measure that may not be necessary if the damage is within allowable limits. Continuing operations without further inspection introduces unnecessary risk to both the engine and aircraft operation. Thus, consulting the manufacturer's guidelines is the best course of action to maintain airworthiness.
