What should you do if you find contaminants in the fuel?

When contaminants are found in the fuel, the most appropriate action is to inspect the fuel system with a mechanic. This choice emphasizes the importance of safety and thoroughness in addressing potential issues that could compromise the helicopter's performance and safety. Contaminants can affect engine operation and lead to serious mechanical failures, so it's crucial to have an experienced professional assess the situation.

Consulting a mechanic ensures that all aspects of the fuel system are examined, including the fuel lines, filters, and tanks, to identify the source and extent of the contamination. This approach helps prevent any hazardous conditions that might arise from inadequate action.

While filtering contaminants using a strainer may seem like a quick fix, it does not address the root cause or ensure comprehensive safety and cleanliness of the entire fuel system. Simply removing fuel and refilling the tank does not guarantee that the new fuel won't also be contaminated, nor does it inspect the system for underlying issues. Continuing to fly as planned is never advisable when there are concerns about fuel quality, as this could jeopardize flight safety.
