SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 42 M-NG
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 excessive voids in the adhesive
joint between the center wing spars and the
[[Page 54801]]
upper center wing skins. This condition could cause the wing to fail,
which could result in loss of control of the airplane. We are issuing
this AD to require actions to address the unsafe condition on these
products.
DATES: This AD is effective October 11, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 11,
2012.

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 June 15, 2012 (77 FR
35890). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
During conversion of a DA 42 to a DA 42 NG, voids were detected
in the adhesive joint between the centre wing spars and the upper
centre wing skins, between the fuselage wall and the engine nacelle.
The available information indicates that wings with voids continue
to meet the certification design limits, provided the voids are
within established criteria.
However, to detect any wings that may have voids exceeding these
criteria, Diamond has issued Mandatory Service Bulletin (MSB) 42-092
and MSB 42NG-022 (single document) that describes instructions for
inspection of the aeroplanes that had these wings installed during
manufacture. Aeroplanes that have voids within the inspection
criteria may continue to operate without restriction, pending the
outcome of ongoing investigations. Aeroplanes that have voids
exceeding the inspection criteria must be repaired.
For reasons described above, the EASA AD required the inspection
of the affected aeroplanes to measure the voids in the adhesive
joint between the centre wing spars and the upper centre wing skins,
the reporting of all findings to Diamond Aircraft Industries and the
repair of any voids exceeding the criteria as specified in the MSB.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 35890, June 15,
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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (77 FR 35890, June 15, 2012) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 35890, June 15, 2012).
Costs of Compliance
We estimate that this AD will affect 172 products of U.S. registry.
We also estimate that it will 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.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $29,240, or $170 per product.
In addition, we estimate that any necessary follow-on actions will
take about 10 work-hours, for a cost of $850 per product. We have no
way of determining the number of products that may need these actions.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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.
