## Abstract

We are adopting a new airworthiness directive (AD) for certain 328 Support Services GmbH Model 328-100 and Model 328-300 airplanes. This AD was prompted by reports of broken bonding wires of certain fuel line clamps. This AD requires repetitive inspections of certain fuel line clamps for discrepancies; repetitive inspections of certain parts for chafing marks; and replacement of any discrepant parts. This AD also includes an optional modification, which is a terminating action for the inspections. We are issuing this AD to address the unsafe condition on these products.
