FAA 2022-23-08

Requires a visual inspection of the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, as well as any applicable corrective actions and application of a torque seal. This AD also requires sending the inspection results to the FAA. Prompted by a recent investigation of a DHC-3 airplane where the lock ring of the stabilizer actuator was found missing.
