## Abstract

We are adopting a new airworthiness directive (AD) for all Hawker Beechcraft Corporation Models 95-C55, D55, E55, 58, and 58A airplanes equipped with a certain STC. This AD requires assuring the airspeed indicator(s) and/or airspeed limitations placard(s) have the correct minimum control speed (V<INF>MC</INF>) markings for the STCs installed. This AD was prompted by information that suggests the affected airplane models with a certain STC installed may not have the appropriate V<INF>MC</INF> markings on the airspeed indicator(s). We are issuing this AD to correct the unsafe condition on these products.
