Airworthiness Directives; Airbus Airplanes

We are revising an earlier notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2015-05-02, which applies to all Airbus Model A318, A319, A320-211, -212, -214, -231, - 232, and -233, and A321 series airplanes. This action revises the NPRM by proposing to require revising the maintenance or inspection program to incorporate new or revised structural inspection requirements and adding airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
