Unsafe Condition

Loose bolts common to the flange of the rudder front spar and main thrust hinge and actuator assembly, as well as the auxiliary actuator support fitting, could cause the rudder actuator to separate from the rudder during certain flight conditions, resulting in loss of rudder control and consequent loss of control of the airplane.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Perform a one-time general visual inspection to identify the material of the rudder assembly. For airplanes with a graphite assembly, perform repetitive general visual inspections of the flange bolts of the rudder front spar for any loose bolts. Retorque or replace the flange bolts as necessary, and contact Boeing or a designated engineering representative for certain conditions.
