Airworthiness Directive · Amendment 39-17136 · Flight controls
Glasflugel Gliders
Superseded. A later AD replaced this one: AD 2012-15-07 R1. Comply with the one in force.
This AD applies to the following Glasflugel models and serial number (S/N) gliders, certificated in any category:
(1) Club Libelle 205, all S/Ns
(2) Kestrel, all S/Ns, except S/N 85, 110, and 125
(3) Mosquito, all S/Ns
(4) Standard Libelle-201B, S/N 169
We are adopting a new airworthiness directive (AD) for Glasflugel Models Standard Libelle-201B, Club Libelle 205, Mosquito, and Kestrel 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 corrosion damage to the elevator control rod that could lead to failure of the elevator control rod, possibly resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) Within 30 days after September 11, 2012 (the effective date of this AD), inspect the elevator control rod in the vertical fin following Glasfaser Flugzeug-Service GmbH Technical Note TN 201-40, TN 205-27, TN 206-26, TN 303-25, TN 304-12, TN 401-30, TN 501-10, and TN 604-11, Revision 1, dated July 14, 2011 (EASA translation approval dated September 9, 2011), as applicable to glider model.
(2) If you find any discrepancy in the inspection required by paragraph (f)(1) of this AD, before further flight, replace the elevator control rod with an elevator control rod that does not have a control bore hole, following Glasfaser Flugzeug-Service GmbH Technical Note TN 201-40, TN 205-27, TN 206-26, TN 303-25, TN 304-12, TN 401-30, TN 501-10, and TN 604-11, Revision 1, dated July 14, 2011 (EASA translation approval dated September 9, 2011), as applicable to glider model.
(3) Within 9 months after September 11, 2012 (the effective date of this AD), unless already done as required by paragraph (f)(2) of this AD, replace the elevator control rod in the vertical fin with an elevator control rod that does not have a control bore hole, following Glasfaser Flugzeug-Service GmbH Technical Note TN 201-40, TN 205-27, TN 206-26, TN 303-25, TN 304-12, TN 401-30, TN 501-10, and TN 604-11, Revision 1, dated July 14, 2011 (EASA translation approval dated September 9, 2011), as applicable to glider model.
(4) As of September 11, 2012 (the effective date of this AD), do not install an elevator control rod with a control bore hole.
(5) The actions mandated by this AD may be accomplished by persons authorized to perform maintenance in accordance with 14 CFR 43.3 and by persons authorized to approve aircraft for return to service after maintenance in accordance with 14 CFR 43.7.
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.
