E:\FR\FM\14APP1.SGM 14APP1 20828 Federal Register / Vol. 79, No. 71 / Monday, April 14, 2014 / Proposed Rules Discussion On November 22, 2013, we issued AD 2013–24–14, Amendment 39–17689 (78 FR 72568; December 3, 2013). That AD required actions intended to address an unsafe condition on Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The inspections required by AD 2013–24–13 are tied to calendar time and the Major Structural Inspection (MSI) identified in Chapter 5 of the airplane maintenance manual (AMM). This compliance time mirrors the mandatory continuing airworthiness information (MCAI) issued by the State of Design for these products. However, U.S. operators are not required to comply with the requirement to inspect before the next MSI since the Limitations in Chapter 4 of the AMM are mandatory and the MSI in Chapter 5 of the AMM is not mandatory. mstockstill on DSK4VPTVN1PROD with PROPOSALS Relevant Service Information Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin MSB 40–074, MSB D4–094, and MSB F4–028 (co-published as a single document), dated May 10, 2013; Diamond Aircraft Industries GmbH Work Instructions WI–MSB 40–074, WI–MSB D4–094, and WI–MSB F4–028, (co-published as a single document), dated May 10, 2013; and DA 40 Series AMM, Chapter Section 05–28–50, Section 2 (Cockpit), page 11, Item 31, sub-item ‘‘The rear main bulkhead,’’ Rev. 7, dated April 1, 2013. 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 747 products of U.S. registry. We also estimate that it would take about 6 work-hours per product to VerDate Mar<15>2010 16:59 Apr 11, 2014 Jkt 232001 comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $100 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $455,670, or $610 per product. the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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 proposed 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. § 39.13 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. (d) Subject Air Transport Association of America (ATA) Code 57: Wings. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 [Amended] 2. The FAA amends § 39.13 by removing Amendment 39–17689 (78 FR 72568; December 3, 2013), and adding the following new AD: ■ Diamond Aircraft Industries GmbH: Docket No. FAA–2014–0226; Directorate Identifier 2014–CE–009–AD. (a) Comments Due Date We must receive comments by May 29, 2014. (b) Affected ADs This AD supersedes AD 2013–24–14, Amendment 39–17689 (78 FR 72568; December 3, 2013).

(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. We are issuing this proposed AD to correct an incorrect compliance time and to modify the aft main spar in the cabin area to ensure the structural integrity of the airplane.

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 
Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes that 
would supersede AD 2013-24-14, which resulted 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 the 
fatigue strength found in the aft main spar not ensuring unlimited 
lifetime structural integrity. We are issuing this proposed AD to 
require actions to address the unsafe condition on these products and 
to change the compliance time to coincide with other regulatory 
requirements.

DATES: We must receive comments on this proposed AD by May 29, 2014.

Discussion

    On November 22, 2013, we issued AD 2013-24-14, Amendment 39-17689 
(78 FR 72568; December 3, 2013). That AD required actions intended to 
address an unsafe condition on Diamond Aircraft Industries GmbH Models 
DA40 and DA40F airplanes and was based on mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country.
    The inspections required by AD 2013-24-13 are tied to calendar time 
and the Major Structural Inspection (MSI) identified in Chapter 5 of 
the airplane maintenance manual (AMM). This compliance time mirrors the 
mandatory continuing airworthiness information (MCAI) issued by the 
State of Design for these products.
    However, U.S. operators are not required to comply with the 
requirement to inspect before the next MSI since the Limitations in 
Chapter 4 of the AMM are mandatory and the MSI in Chapter 5 of the AMM 
is not mandatory.

Relevant Service Information

    Diamond Aircraft Industries GmbH has issued Mandatory Service 
Bulletin MSB 40-074, MSB D4-094, and MSB F4-028 (co-published as a 
single document), dated May 10, 2013; Diamond Aircraft Industries GmbH 
Work Instructions WI-MSB 40-074, WI-MSB D4-094, and WI-MSB F4-028, (co-
published as a single document), dated May 10, 2013; and DA 40 Series 
AMM, Chapter Section 05-28-50, Section 2 (Cockpit), page 11, Item 31, 
sub-item ``The rear main bulkhead,'' Rev. 7, dated April 1, 2013. 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 747 products of U.S. 
registry. We also estimate that it would take about 6 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $100 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $455,670, or $610 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 proposed 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.
