Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes, Model A330-200 Freighter series airplanes, and Airbus Model A340-541 and A340-642 airplanes. This proposed AD was prompted by a report of an under- torqued forward engine mount bolt. This proposed AD would require a one-time torque check of the forward and aft engine mount bolts, and corrective actions if necessary. We are proposing this AD to detect and correct improperly torqued engine mount bolts, which could lead to detachment of the engine from the airplane during flight; and consequent damage to the airplane and injury to persons on the ground.
