Airworthiness Directives; BURKHART GROB LUFT-UND-RAUMFAHRT GmbH & Co. KG, Model G 103 C Twin III SL Sailplanes
The FAA adopts a new airworthiness directive (AD) that supersedes AD 97-24-09, which applies to certain BURKHART GROB LUFT- UND-RAUMFAHRT GmbH & Co. KG (Grob) Model G 103 C Twin III SL sailplanes. AD 97-24-09 currently requires repetitively inspecting the propeller bearing and upper pulley wheel for increased play and, if increased play is found, modifying the propeller bearing and pulley wheel. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. Consequently, this AD requires you to modify the propeller bearing and upper pulley wheel by installing a new securing plate and tightening the grooved nut to the new torque values. We are issuing this AD to prevent loss of the sailplane propeller caused by increased play in the current design propeller bearing and upper pulley wheel. This could result in loss of control of the sailplane.
