## Abstract

We are adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Models A36TC, B36TC, S35, V35, V35A, and V35B airplanes. This AD was prompted by a fatal accident where the exhaust tailpipe fell off during takeoff. This AD adds a life limit to the exhaust tailpipe v-band coupling (clamp) that attaches the exhaust tailpipe to the turbocharger and requires an annual visual inspection of the exhaust tailpipe v-band coupling (clamp). We are issuing this AD to address the unsafe condition on these products.
