I’m sure your manual has something similar to this:
§121.557 Emergencies: Domestic and flag operations.
(a) In an emergency situation that requires immediate decision and action the pilot in command may take any action that he considers necessary under the circumstances. In such a case he may deviate from prescribed operations procedures and methods, weather minimums, and this chapter, to the extent required in the interests of safety.
If you’re sure you’ve isolated the leak, nod, smile and go about your day.
