Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-223F, -223, -321, -322, and -323 airplanes. This proposed AD was prompted by fatigue load analysis that determined that the inspection interval for certain pylon bolts must be reduced. This proposed AD would require a torque check of forward engine mount bolts, and replacement if necessary. We are proposing this AD to detect and correct loose or broken bolts, which could lead to engine detachment in-flight, and damage to the airplane.
