Pilot narrative
Verbatim, de-identified by NASA. Placeholders: ZZZ,
X, Y.
Flying from ZZZ to ZZZ1 the Propeller Heat System Failed. I was still climbing through a layer which appeared to top at about 24000 feet. I was assessing the warning and CAWS (Central Advisory and Warning System) indicating that the Prop Heat failed and following the QRH, when the autopilot began banking the aircraft to the right and nose down. I disconnected the autopilot and hit the trim interrupt switch to ensure to have full control over the aircraft. Once I was back straight and level, ATC inquired why we had descended and if we were okay. I was able to climb out of icing and proceeded back on course.
