Full official abstract

The FAA adopts a new airworthiness directive (AD) for certain BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Grob) Models G103 Twin ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103 C Twin III SL sailplanes. This AD requires you to replace the center of gravity (CG) release hook attachment brackets with brackets of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent abnormal or uncontrolled sailplane release due to cracked CG release hook attachment brackets. This condition could result in reduced or loss of sailplane control.
