Summary
We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2016-12-09, which applies to certain Airbus Model A330- 200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. This action revises the notice of proposed rulemaking (NPRM) by revising the compliance time for the modification of the inside center wing box (CWB). We are proposing this AD to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes.
