Unsafe Condition

The -27 bolt attaching the stabilator trim tab actuator to the bellcrank may lack a properly installed nut, leading to potential separation of the actuator from the linkage.

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

Required Actions

Inspect the -27 bolt for a properly installed nut. If the nut is loose or missing, replace the bolt assembly with an AN3-6 bolt, AN960-10 washer, AN310-3 nut, and MS24665-134 cotter pin. Record compliance details and notify the FAA within 48 hours if the nut was missing or loose.
