If the FUEL 1 BYPASS caution appears, what is wrong with the fuel system?

Explanation:
When the FUEL 1 BYPASS caution shows, it means the fuel filter for engine 1 has opened its bypass path. The UH-60S fuel system uses a bypass valve in the engine 1 filter that automatically opens to maintain fuel flow if the filter element is contaminated or severely clogged. In this situation, fuel still reaches the engine, but it bypasses the filtration, signaling a contamination issue that needs service. So the correct interpretation is that the #1 engine fuel filter has bypassed due to contamination. Other conditions would present different cautions or symptoms (like pump failure or a fuel leak), so they don’t match this alert as specifically.
