Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2011-19- 04, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2011-19-04 currently requires repetitive inspections of the left- hand and right-hand inboard and outboard elevator servo-control rod eye-ends for cracking, and corrective actions if necessary. Since we issued AD 2011-19-04, we have determined that certain elevator servo- control parts that do not conform to the approved type design have been installed and may have the potential of cracks in the rod eye-end. This proposed AD would also require an inspection to determine if certain elevator servo-control parts are installed, and replacement if necessary. We are proposing this AD to detect and correct rod eye-end cracking, which could result in an uncontrolled elevator surface and consequent reduced control of the airplane.
