Pilot narrative
Verbatim, de-identified by NASA. Placeholders: ZZZ,
X, Y.
During cruise at FL250 en route from ZZZ to ZZZ1, with visible ice on the airframe, a rough propeller vibration occurred with no associated CAS messages. All de ice and anti ice systems in the aircraft were working perfectly and keeping up with the ice accretion. Different power settings did not minimize the vibration and it lasted for approximately 2 minutes. Power and performance was degraded and the crew worked together on the issue and decided to descend and divert to ZZZ2 where we safely landed the aircraft.
