A propeller malfunction led to a 2020 runway excursion of an ATR 42 in Canada, according to a newly released investigation report. The propeller entered a pitch-lock condition, causing an asymmetric thrust state when reverse thrust was selected after touchdown. Directional control was lost and the aircraft veered off the runway.
