SUPPLEMENTARY INFORMATION: Discussion TKELLEY on DSK3SPTVN1PROD with RULES 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. VerDate Mar<15>2010 16:13 Sep 05, 2012 Jkt 226001 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: • Are consistent with the intent that was proposed in the NPRM (77 FR 35890, June 15, 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 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 workhours 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: PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 54801 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.

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

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:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 35890, June 15, 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 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

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.

(d) Subject

    Air Transport Association of America (ATA) Code 57, Wings.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated 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 upper 
center wing skins. We are issuing this AD to prevent wing failure, 
which could result in loss of control of the airplane.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Within the next 100 hours time-in-service (TIS) after 
October 11, 2012 (the effective date of this AD) or within the next 
3 months after October 11, 2012 (the effective date of this AD), 
whichever occurs first, inspect the adhesive joint between the 
center wing spars and the upper center wing skin following Diamond 
Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-
42NG-22, dated May 20, 2011, as specified in Diamond Aircraft 
Industries GmbH Mandatory Service Bulletin No. MSB 42-092, MSB 42NG-
022, dated May 20, 2011.
    (2) Within 30 days after the inspection required in paragraph 
(f)(1) of this AD, using Appendix A of Diamond Aircraft Industries 
GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 
2011, report the results of the inspection to Diamond Aircraft 
Industries GmbH at the address in paragraph (i)(3) of this AD.
    (3) If, during the inspection required in paragraph (f)(1) of 
this AD, voids are detected that exceed the criteria specified in 
Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-
MSB-42NG-22, dated May 20, 2011, before further flight, repair the 
airplane following Diamond Aircraft Industries GmbH Work Instruction 
WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011, as specified in 
Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 
42-092, MSB 42NG-022, dated May 20, 2011.
    (4) For the purpose of compliance with paragraph (f)(3) of this 
AD, a single positioning flight is allowed to a location where the 
repair can be done following the provisions specified in Section 
III.1 of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-

mike.kiesov@faa.gov. Before using any approved AMOC on any airplane 
to which the AMOC applies, notify your appropriate principal 
inspector (PI) in the FAA Flight Standards District Office (FSDO), 
or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, a federal agency may not conduct or sponsor, and a person 
is not required to respond to, nor shall a person be subject to a 
penalty for failure to comply with a collection of information 
subject to the requirements of the Paperwork Reduction Act unless 
that collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing, and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the burden should be directed to
