Airworthiness Directives; Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Gliders


AGENCY:
 
Federal Aviation Administration (FAA), DOT.


ACTION:
 
Final rule; request for comments.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
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.


DATES:
 
This final rule is effective October 24, 2014.


The Director of the Federal Register approved the incorporation by reference of certain


publications listed in this AD as of August 27, 2014 (79 FR 42658, July 23, 2014).


We must receive comments on this AD by December 8, 2014.

SUPPLEMENTARY INFORMATION:


Discussion


On July 14, 2014, we issued AD 2014-15-02, Amendment 39-17904 (79 FR 42658, July 23,


2014), 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. That AD required inspection of the rudder control unit


for installation of plastic cable pulleys and replacement of plastic cable pulleys with aluminum cable


pulleys. That AD resulted from 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 issued that AD to require actions to address the unsafe


condition on these products.


Actions Since AD Was Issued


Since we issued AD 2014-15-02 (79 FR 42658, July 23, 2014), it was determined that to avoid


any confusion regarding applicability to a given glider, the AD should be revised to include


references to certain suffixes of S/Ns in paragraph (c) Applicability.


Relevant Service Information


We reviewed Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Service Bulletin SB-G05,


dated January 17, 2014; and Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Instructions A/I-


G05, dated January 17, 2014. The service information describes procedures for inspection of the


rudder control unit for installation of plastic cable pulleys and replacement of plastic cable pulleys


with aluminum cable pulleys.
