## Summary

We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2011-24-06. AD 2011-24-06 applies to all BAE Systems (Operations) Limited Model Bae 146-100A, -200A, and -300A airplanes; and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes. This action revises the NPRM by 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 those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
