Airworthiness Directives; HB Aircraft Industries AG HB-23 2400 Hobbyliner/Scanliner Sailplanes

摘要

This amendment adopts a new airworthiness directive (AD) that applies to certain HB Aircraft Industries AG HB-23 2400 Hobbyliner/ Scanliner sailplanes. This action requires inspecting the rudder bearing support bracket for cracks, replacing the bracket if cracked, and modifying the bracket with a third bolt, if no cracks are found. Cracks found in the rudder bearing support brackets prompted this action. The actions specified by this AD are intended to prevent cracks in the rudder bearing support bracket, which could cause loss of control of the rudder and possible loss of the sailplane.
