We are adopting a new airworthiness directive (AD) for GROB- WERKE GMBH & CO KG Models G102 STANDARD ASTIR III, G102 CLUB ASTIR III, and G102 CLUB ASTIR IIIb gliders and BURKHART GROB LUFT--UND RAUMFAHRT GmbH & CO KG Models G103 TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G 103 C Twin III SL gliders. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as plastic control cable pulleys developing cracks due to aging. We are issuing this AD to require actions to address the unsafe condition on these products.
(1) For all Models G103C TWIN III ACRO and G 103 C Twin III SL gliders: Within 3 months after August 27, 2014 (the effective date of this AD), inspect the rudder control unit for installation of plastic cable pulleys. If plastic cable pulleys are installed, before further flight, replace the plastic cable pulleys with aluminum cable pulleys following the actions and instructions of Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Service Bulletin SB-G05 and Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Instructions A/I-G05, both dated January 17, 2014.
(2) For all Models G102 STANDARD ASTIR III, G102 CLUB ASTIR III, G102 CLUB ASTIR IIIb, G103 TWIN II, and G103A TWIN II ACRO gliders: Within 1 month after August 27, 2014 (the effective date of this AD), inspect the rudder control unit for installation of plastic cable pulleys. If plastic cable pulleys are installed, before further flight, replace the plastic cable pulleys with aluminum cable pulleys following the actions and instructions of Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Service Bulletin SB-G05 and Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Instructions A/I-G05, both dated January 17, 2014.
(3) As of August 27, 2014 (the effective date of this AD), do not install any plastic control cable pulley in the rudder control unit of any glider identified in paragraphs (c)(1) through (c)(7) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
