## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A320-214 and-232 airplanes. This proposed AD was prompted by reports that medium-head fasteners were installed in lieu of shear-head fasteners on a certain upper panel which manufacturer fatigue and damage tolerance analyses demonstrated could have an affect on panel fatigue life. This proposed AD would require repetitive inspections for cracking of certain fasteners, and repairs if necessary. We are proposing this AD to detect and correct cracking which could result in the loss of structural integrity of the airplane.
