## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318-112, and -121; A319-111, -112, -115, -132, and -133; A320-214, -232, and -233; and A321-211, -212, -213, and -231 airplanes. This proposed AD was prompted by reports that some nuts installed on the wing, including on primary structural elements, were found cracked. This proposed AD would require inspecting to determine if certain nuts are installed or cracked, and replacing the affected nuts if necessary. We are proposing this AD to detect and correct missing and cracked nuts, which could result in the structural integrity of the airplane wings being impaired.
