Full official abstract
The FAA adopts a new airworthiness directive (AD) to supersede AD 2004-08-13, which applies to certain BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Burkhardt Grob) Models G103 TWIN ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103 C Twin III SL sailplanes. AD 2004-08-13 currently requires you to replace the center of gravity (CG) release hook attachment brackets with brackets of improved design. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. This AD retains all the actions required in AD 2004-08-13 and adds Model G103A TWIN II ACRO sailplanes to the applicability. 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.
