AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform an eddy current inspection of the actuator cylinder head lugs for cracking or corrosion, as specified in Raytheon Service Bulletin 32-3391. If no cracking or corrosion is found, accomplish follow-on actions (e.g., vibro-etching the MLG actuator data plate, painting a blue stripe, replacing bushings, and applying corrosion protection). If any cracking or corrosion is found, replace the actuator or the actuator cylinder head with a new one.
