## Abstract

We are adopting a new airworthiness directive (AD) for certain 328 Support Services GmbH Model 328-300 airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by a determination that incomplete inspection instructions exist for the skin under outer and inner doublers left installed after the removal of a certain data link system. We are issuing this AD to address the unsafe condition on these products.
