Summary
We are revising an earlier proposal for certain Airbus Model A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, and Model A300 F4-600R series airplanes. This action revises the notice of proposed rulemaking (NPRM) by extending the area to be inspected for cracking. This SNPRM also proposes to require an additional inspection for previously inspected airplanes. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
