Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2011– 0100, dated May 26, 2011 (referred to after this as ‘‘the MCAI’’), 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 E:\FR\FM\15JNP1.SGM 15JNP1 Federal Register / Vol. 77, No. 116 / Friday, June 15, 2012 / Proposed Rules 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. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin No. MSB 42–092 MSB 42NG–022, dated May 20, 2011, and Work Instruction WI–MSB–42–092 WI–MSB–42NG–22, dated May 20, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. srobinson on DSK4SPTVN1PROD with PROPOSALS FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD will affect 172 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 proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $29,240, or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 10 work-hours, for a cost of $850 per product. We have no way of VerDate Mar<15>2010 16:34 Jun 14, 2012 Jkt 226001 determining the number of products that may need these actions. According to the manufacturer, some of the costs of this proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: (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.

Airworthiness Directives; Diamond Aircraft Industries GmbH 
Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 
42 M-NG airplanes. This proposed AD results from 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. This condition could cause the wing to fail, which 
could result in loss of control of the airplane. We are issuing this 
proposed AD to require actions to address the unsafe condition on these 
products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2011-0100, dated May 26, 2011 (referred to after this as ``the 
MCAI''), 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

[[Page 35891]]

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.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Diamond Aircraft Industries GmbH has issued Mandatory Service 
Bulletin No. MSB 42-092 MSB 42NG-022, dated May 20, 2011, and Work 
Instruction WI-MSB-42-092 WI-MSB-42NG-22, dated May 20, 2011. The 
actions described in this service information are intended to correct 
the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 172 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 proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $29,240, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
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 proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.

42.AC030 through 42.AC052, certificated in any category.

(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 the 
effective date of this AD or within the next 3 months after 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
