ACTION:
 
Final rule; request for comments.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are revising an airworthiness directive (AD) for certain Diamond Aircraft


Industries GmbH Models HK 36 R, HK 36 TS, and HK 36 TTS powered gliders. AD 2013-04-08


required replacement of each elevator bell crank assembly and elevator bell crank mount. This AD


retains the actions of AD 2013-04-08 but decreases gliders in the Applicability by removing the


Model H-36 from the Applicability. This AD was prompted by reports of installation of an unsuitable


self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator,


resulting in loss of control. We are issuing this AD to correct the unsafe condition on these products.


DATES:
 
This final rule is effective May 6, 2013.


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


publications listed in this AD as of April 9, 2013 (78 FR 14160, March 5, 2013).


We must receive any comments on this AD by June 20, 2013.

SUPPLEMENTARY INFORMATION:


Discussion


On February 14, 2013, we issued AD 2013-04-08, amendment 39-17365 (78 FR 14160, March


5, 2013), for all Diamond Aircraft Industries GmbH Models HK 36 R, HK 36 TS, and HK 36 TTS


powered gliders. That AD requires replacement of the elevator bell crank assembly and elevator bell


crank mount. That AD resulted from installation of an unsuitable self-locking nut on the bell crank of


the elevator push rod that can cause failure of the elevator, 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 2013-04-08 (78 FR 14160, March 5, 2013), it was determined that Model


H-36 airplanes do not have the elevator control and bellcrank assembly part numbers associated with


the unsafe condition of this AD. Since Model H-36 airplanes do not have the unsafe condition, it is


not necessary or possible for those airplanes to comply with this AD, so we are removing the Model


H-36 from the Applicability section.


Relevant Service Information


We reviewed Diamond Aircraft Industries GmbH Mandatory Service Bulletin MSB 36-108,


dated February 28, 2012; and Diamond Aircraft Industries GmbH Work Instruction WI-MSB 36-108,


dated February 28, 2012. The service information describes procedures for replacement of the


elevator bell crank assembly and elevator bell crank mount.


FAA's Determination


We are issuing this AD because we evaluated all the relevant information and determined it is


not necessary or possible for Diamond Aircraft Industries GmbH Model H-36 airplanes to comply


with the previous AD.
