AD FAA-2014-0292

We are adopting a new airworthiness directive (AD) for Fiberglas-Technik Rudolf Lindner GmbH & Co. KG (type certificates formerly held by GROB-WERKE GMBH & CO KG and BURKHART GROB LUFT- UND RAUMFAHRT GmbH & CO KG) Models G102 STANDARD ASTIR III, G102 CLUB ASTIR III, G102 CLUB ASTIR IIIb, G103 TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G 103 C Twin III SL gliders. This AD revises AD 2014-15- 02, which required inspection of the rudder control unit for installation of plastic cable pulleys and replacement of plastic cable pulleys with aluminum cable pulleys. This AD retains the actions of AD 2014-15-02 but clarifies the suffixes of serial numbers (S/Ns) in paragraph (c) Applicability. This AD was prompted by reports of plastic control cable pulleys developing cracks due to aging, which could lead to breaking of the pulley and potentially jamming the rudder control unit, possibly resulting in loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.
