Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain 328 Support Services GmbH Model 328-100 airplanes and 328 Support Services GmbH Model 328-300 airplanes. This proposed AD was prompted by reports of broken bonding wires of certain fuel line clamps. This proposed AD would require a one-time inspection of certain fuel line clamps for discrepancies, and replacement of any discrepant clamps. We are proposing this AD to address the unsafe condition on these products.
