Unsafe Condition
Clogging of the preference injector, if not detected and corrected, and if combined with a sharp reduction in the fuel flow during the flight after a pilot command, could lead to a flameout in the combustion chamber, which could result in an uncommanded in-flight shutdown of the engine and reduced control of the helicopter.
