Several Bearhawk owners have reported wear observed on the inside of the exterior fuselage flap pulleys, generally at around 400 flight (landing) cycles. This appears to be caused by the flap cables changing direction in two planes at this point, and is more accentuated on the left pulley.
The pulley wears on the inside. It can be removed and flipped 180° to double the pulley life. It is easily observed on a routine inspection and easy to change.
