AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for Diamond
Aircraft Industries GmbH
[[Page 14161]]
Model H-36, HK 36 R, HK 36 TS, and HK 36 TTS airplanes. 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 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 require actions
to address the unsafe condition on these products.
DATES: This AD is effective April 9, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of April 9, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on November 5, 2012 (77
FR 66409). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A HK 36 R aeroplane recently experienced an in-flight elevator
control failure after take-off which resulted in an uncontrolled
landing. The results of the subsequent investigation revealed that
the elevator control rod had disconnected from the elevator bell
crank in the tail section of the fuselage, as a result of
installation of a non-suitable self-locking nut.
The subsequent design review of the affected elevator bell crank
joint with elevator control rod identified that its current
configuration has a failure potential when components such as thin
self-securing nuts and bearings are aging and original clearance of
the control system cannot be maintained in service. Both the designs
of elevator bell crank and elevator control rod are installed in DV
20 aeroplanes.
This condition, if not corrected, could lead to further cases of
elevator control failure, likely resulting in reduced control of the
aeroplane, consequent damage to the aeroplane and injury to the
occupants.
To address this concern, Diamond Aircraft Industries (DAI)
published Mandatory Service Bulletin (MSB) 36-108 and MSB 20-061/1
to improve the affected elevator control joint by embodiment of new
design which prevents elevator bell crank and push rod
disconnection.
For reasons described above, this AD requires replacement of
aeroplane elevator bell cranks with improved parts and prohibits
installation of any previous design elevator bell crank.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 66409, November 5,
2012) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 66409, November 5, 2012) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 66409, November 5, 2012).
Costs of Compliance
We estimate that this AD will affect 25 products of U.S. registry.
We also estimate that it would take about 2 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts would cost about $352 per product.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $13,050, or $522 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
For the reasons discussed above, I certify this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.
