Summary
We are revising an earlier proposal for all Textron Aviation Inc. Models A36TC and B36TC airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding all Textron Aviation Inc. Models S35, V35, V35A, and V35B airplanes that have the optional turbocharger engine installed to the applicability and adding an annual visual inspection of the exhaust tailpipe v-band coupling (clamp). We are proposing this airworthiness directive (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.
