Unsafe Condition
Fatigue cracking found on the rudder horn spar could lead to detachment of the mass balance weight of the rudder, which could jam or restrict the movement of the rudder, resulting in reduced controllability of the airplane. Loss of a mass balance weight could also damage other parts of the airplane, leading to reduced controllability or injury to a person or damage to property on the ground.
