Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A320-111, -211, -212, and -231 airplanes. This proposed AD was prompted by reports of broken struts of the center wing box (CWB). This proposed AD would require a detailed inspection of the CWB struts for cracking, and repair if necessary. We are proposing this AD to detect and correct cracked or broken struts, which could result in strut failure and consequent reduced structural integrity of the airplane.
