## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. The existing AD currently requires a revision of the airplane flight manual to include procedures for a pre-flight elevator check before each flight, repetitive inspections for cracks of the attachment lugs of the mode selector valve position transducers on the elevator servo controls, and corrective actions if necessary. This proposed AD would retain the existing requirements, reduce the applicability of the existing AD, and add terminating actions. For certain airplanes, this proposed AD would require upgrading the flight control primary computers. This proposed AD results from cracks of the transducer body at its attachment lugs. We are proposing this AD to ensure proper functioning of the elevator surfaces, and to prevent cracking of the attachment lugs, which could result in partial loss of elevator function and consequent reduced controllability of the airplane.
