AD 2005-26-14 70 FR 76676

The FAA adopts a new airworthiness directive (AD) for all BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Burkhardt Grob) Model G103 TWIN ASTIR sailplanes. This AD requires you to replace the elevator lever, part number (P/N) 103-3521, with an improved design part, P/N 103-3523. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent cracks in the elevator lever, which could cause the elevator lever to fail. This failure could result in loss of control of the sailplane.
