Unsafe Condition

Insufficient clearance between the actuator support seal tube and spring capsule assembly in the rudder trim and load-feel actuator assembly, leading to moisture accumulation that could freeze and cause stiff operation, binding, or jamming of the rudder trim control system and consequent jamming of the rudder.
