Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede airworthiness directive (AD) 2011-14- 06 that applies to all Airbus Model A318, A319, A320, and A321 series airplanes. That AD currently requires revising the maintenance program. Since we issued that AD, we have determined that more restrictive limitations are necessary. This proposed AD would require revising the maintenance program to incorporate new limitations. We are proposing this AD to prevent fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
