## Summary

We are revising an earlier proposal for an airworthiness directive (AD) for certain 328 Support Services GmbH Model 328-100 and Model 328-300 airplanes. This action revises the notice of proposed rulemaking (NPRM) by expanding the applicability and making certain inspections repetitive. 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.
