Abstract
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by a report that the trimmable horizontal stabilizer actuator (THSA) might not function as intended after failure of the primary load path. This AD requires repetitive detailed visual inspections for discrepancies of the THSA upper attachments and no-back housing. We are issuing this AD to address the unsafe condition on these products.
