This Airworthiness Directive requires operators of specified Beechcraft 300-series aircraft (serial numbers listed in Raytheon MSB SB 27‑3187 Rev 1) to verify logbooks and, where elevators have been removed or records are incomplete, inspect and, if necessary, replace elevator balance weight attachment screws with drilled‑head NAS6703HU12–HU22 bolts secured by safety‑wire. Inspections must occur within 200 flight hours and any incorrect bolts must be corrected before further flight; the AD addresses an unsafe condition in elevator balance attachment hardware.
