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.
Within 6 months after the effective date of this AD, do a general visual inspection of all Hydraflow fuel line clamps for worn and missing bonding wires; do a general visual inspection of the jet pump outlet, connection part, and fuel lines for chafing marks; and for parts with chafing marks, before further flight, measure the depth of the chafing marks; in accordance with the Accomplishment Instructions of the service information specified in paragraph (g)(1) or (g)(2) of this AD, as applicable. Repeat the inspections thereafter at intervals not to exceed 2,500 flight hours.
