## Abstract

We are superseding Airworthiness Directive (AD) 2016-02-01, which applied to certain Airbus Model A320-211, -212, and -231 airplanes. AD 2016-02-01 required repetitive inspections to detect cracks of the pressurized floor fittings at a certain frame, and renewal of the zone protective finish or replacement of fittings with new fittings if necessary. AD 2016-02-01 also provided an optional modification that was terminating action for the repetitive inspections. This new AD retains the requirements of AD 2016-02-01, and requires accomplishment of the modification that was optional in AD 2016-02-01. This AD was prompted by the results of an additional fatigue analysis of cracking of the pressurized floor fittings and a determination that the optional modification should become a required action. We are issuing this AD to address the unsafe condition on these products.
