AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the throttle control cable by removing engine cowling, disconnecting the cable from the carburetor throttle arm, and removing the carburetor. Check for binding or roughness, apply 50 lbs. pressure and mark the cable, then apply 50 lbs. pulling force and mark again. If the cable gives under loading, shows binding, or marks are 0.25 inch apart, replace the throttle control assembly. Replace carburetor throttle shaft and stop arm assembly with specified parts based on carburetor model. Reinstall carburetor, rig the cable with a 1/16 inch cushion, torque the nut to 25/60 in. lbs., and safety with a cotter pin. Equivalent methods require FAA approval.
