## Summary

We are revising an earlier proposal, which would have applied to certain Airbus SAS Model A350-941 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding airplanes to the applicability and proposing to require revised maintenance requirements and airworthiness limitations. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these changes would impose an additional burden over the proposed requirements in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
